Microskopic Observation

CHAPTER I
INTRODUCTION
A.    Background
Each of living thing has different shape and charecter. Human are different with animal and plant. Plant has stem, root and leaves, but human and animal haven’t it. Human and animal have feet, hand, and the other organs that plant hasn’t it. Human and nimal have some commonality but human and animal are not same. One of different is, human is thinking creatur but animal are not.
Progressing of science can answer the question,
is structure of living thing are different? To learn the different, scientists observe to know about the structure of living thing. Invention that make easer to know the sturture of living thing is invention to microscope. Then, microscope used by scientists in their observation.
Based observation by scientists, cell is smallest part of living thing. Cell was finding by Robert Hook. Observation by other scientists, found that cell has part and organels. Cells that it shape and it function are same called tissue. Tissues make up organs and organs make up the body of living thing. Research about structure of living thing more progress so aplently process in body of living thing known.
The result of experiment by sientists prove that the sturcture of living thing are different. Animal and human have much similarity, but plant is very different with animal and human so if learn about living thing, we have to know the structure that they have.
Students of biologi departement will learn many things about living things and should know the basic structure of living things before learning specific things that happen in living organisms. This is base the experiment "Microscope Observation" is done.

CHAPTER II
PREVIEW OF LITERATURE
Tissue is a collection os cells that are closely linked to each other has the same function sturture. The study of the tissue is called histology. Various tissue composed and organized in the form of the organ (Hamka, 2012).
A mature vascular plant (any plant other than mosses and liverworts), contains several types of differentiated cells. These are grouped together in tissues. Some tissues contain only one type of cell.

Xylem conducts water and dissolved minerals from the roots to all the other parts of the plant.In angiosperms, most of the water travels in the xylem vessels. These are thick-walled tubes that can extend vertically through several feet of xylem tissue. Their diameter may be as large as 0.7 mm. Their walls are thickened with secondary deposits of cellulose and are usually further strengthened by impregnation with lignin. The secondary walls of the xylem vessels are deposited in spirals and rings and are usually perforated by pits. Xylem vessels arise from individual cylindrical cells oriented end to end. At maturity the end walls of these cells dissolve away, and the cytoplasmic contents die. The result is the xylem vessel, a continuous nonliving duct (Anonymousa,2012).
The main components of phloem are sieve elements and companion cells, roots, growing tips of stems and leaves,flowers ,fruits, tubers, corms, etc.Sieve elements have no nucleus and only a sparse collection of other organelles. They depend on the adjacent companion cells for many functions. Companion cells move sugars, amino acids and a variety of macromolecules into and out of the sieve elements. In "source" tissue, such as a leaf, the companion cells use transmembrane proteins to take up — by active transport — sugars and other organic molecules from the cells manufacturing them. Water follows by osmosis. These materials then move into adjacent sieve elements through plasmodesmata. The pressure created by osmosis drives the flow of materials through the sieve tubes. In "sink" tissue, the sugars and other organic molecules leave the sieve elements through plasmodesmata connecting the sieve elements to their companion cells and then pass on to the cells of their destination (Anonymousa,2012).
Tissue is a collection os cells that are closely linked to each other has the same function sturture. The study of the tissue is called histology. Various tissue composed and organized in the form of the organ (Hamka, 2012).
All plant parts consist of the same three types of tissues. The ground tissue system, which makes up the bulk of the plant, has many functions such as photosynthesis and food storage. Pipelines of the vascular tissue system thread through ground tissue. They distribute water and nutrients to all parts of the plant body. The dermal tissue system covers and protects the plant’s exposed surfaces. These three plant tissue systems are made up of cells organized as simple and complex tissues. Simple tissues consist primarily of one type of cell; examples include parenchyma, collenchyma, and sclerenchyma. Complex tissues have two or more cell types. Xylem, phloem, and epidermis are examples. You will learn more about all of these tissues in the next section.The same tissues form in all flowering plants, but they do so in different patterns. Monocots and eudicots are named after their cotyledons, which are leaflike structures that contain food for a plant embryo. These “seed leaves” wither after the seed germinates and the developing plant begins to make its own food by photosynthesis. Cotyledons consist of the same types of tissues in all plants that have them, but the seeds of eudicots have two cotyledons and those of monocots have only one (Starr, 2011).
Meristematic tissue Throughout their lives, plants can continue to produce new cells in their meristematic tissues. Meristematic tissues make up meristems regions of rapidly dividing cells. Cells in meristems have large nuclei and small vacuoles or, in some cases, no vacuoles at all. As these cells mature, they can develop into many different kinds of plant cells. Meristematic tissues are located in different regions of a plant (Biggs, 2008).
Dermal tissue, the epidermis The layer of cells that makes up the outer covering on a plant is dermal tissue, also called the epidermis. Cells of the epidermis resemble pieces of a jigsaw puzzle with interlocking ridges and dips.  Most epidermal cells can secrete a fatty substance that forms the cuticle (Biggs,2008).
Vascular tissues Food, water, and other substances are carried throughout your body in your blood vessels. In a plant, the transportation of water, food, and dissolved substances is the main function of two types of vascular tissue xylem and phloem (Biggs,2008).
Ground tissue The category for plant tissues that are not meristematic tissues, dermal tissues, or vascular tissues is ground tissue. Ground tissues consist of parenchyma, collenchyma, and sclerenchyma cells and have diverse functions, including photosynthesis, storage, and support. Most of a plant consists of ground tissue. The ground tissue of leaves and green stems contains cells with numerous chloroplasts that produce glucose for the plant. In some stems, roots, and seeds, cells of ground tissue have large vacuoles that store sugars, starch, oils, or other substances. Ground tissues also provide support when they grow between other types of tissue (Biggs, 2008).
Traditionally, botanists classified anthophytes as monocots or dicots. The names refer to the number of cotyledons in their seeds: monocot one cotyledon, dicot two cotyledons. However, botanists now classify dicots as eudicots or dicots, based on the structure of their pollen. About 75 percent of anthophytes are eudicots and include many trees, shrubs, and garden plants. There are few dicots and examples include maples, oaks, and sycamores. Monocots are the second largest group and include palms, lilies, onions, and grasses (Starr, 2011).
The same tissues form in all flowering plants, but they do so in different patterns. Monocots and eudicots are named after their cotyledons, which are leaflike structures that contain food for a plant embryo. These “seed leaves” wither after the seed germinates and the developing plant begins to make its own food by photosynthesis. Cotyledons consist of the same types of tissues in all plants that have them, but the seeds of eudicots have two cotyledons and those of monocots have only one.  Most shrubs and trees, such as rose bushes and maple trees, are eudicots. Lilies, orchids, and grasses are examples of typical monocots (Biggs, 2008)
Animal tissues can be grouped into four basic types: connective, muscle, nervous, and epithelial. Multiple tissue types comprise organs and body structures. While all animals can generally be considered to contain the four tissue types, the manifestation of these tissues can differ depending on the type of organism. For example, the origin of the cells comprising a particular tissue type may differ developmentally for different classifications of animals (Anonymousb,2012).
Occurring as sheets of cells, epithelial tissue covers the outside of the body and lines organs and cavities within the body. The dose packing of epithelial cells, often involving tight junctions, enables epithelial tissue to function as a barrier against mechanical injury, pathogens, and fluid loss. The cells ofan epithelial tissue, or epithelium, also form active interfaces with the environment. For example, the epithelium that lines the nasal passages has a critical function in olfaction, the sense of smell. Epithelial cell shape may be cuboidal (like dice), columnar (like bricks standing on end), or squamous (like floor tiles). In addition, cells may be arranged in a simple epithelium (single cell layer), a stratified epithelium (multiple tiers of cells), or a pseudostratified epithelium (a single layer of cells varying in height)    (Campbell, 2009).
The most common functions of connective tissues are to bind and support other tissues in the body. Connective tissue consists of a sparse population of cells scattered through an extracellular matrix. The matrix generally consists of a web of fibers embedded in a uniform foundation that may be liquid, jellylike, or solid. This variation in matrix structure is reflected in the six major types of connective tissue in vertebrates: loose connective tissue, cartilage, fibrous connective tissue, adipose tissue, blood, and bone (Campbell, 2009).
The tissue responsible for nearly all types of body movement is muscle tissue. All muscle cells consist of filaments containing the proteins actin and myosin, which together enable musc1es to contract. Muscle is the most abundant tissue in many animals, and muscle activity accounts for much of the energyconsuming cellular work in an active animal. Three types of muscle tissue in the vertebrate body: skeletal, cardiac, and smooth muscle (Campbell, 2009).
The function of nervous tissue is to sense stimuli and transmit signals in the form of nerve impulses from one part ofthe animal to another. Nervous tissue contains neurons, or nerve cells, which have extensions called axons that are uniquely specialized to transmit nerve impulses.  It also indudes different forms ofglial cells, or g1ia, which help nourish, insulate, and replenish neurons. In many animals, a concentration of nervous tissue forms a brain, an information-processing center. As we will discuss next, neurons have a critical role in managing many of the animal's physiological functions (Campbell, 2009).

f.       Its leaf consist of cuticle, epidermis, chloroplast, palisade parenchya,spongy parenchyma, stomata, air space, bundle sheath,xylem and floem. Based on the experiment that has been done,epidermis on dicotyl leaf is divided up two, which is epidermis on and bottom epidermis. It also consist of xylem and phloem.
g.      Epithelial tissue in this case Epithelial cylinder as undercoated as, its cell is made manifest one rather set and get fundamental one be intermediated, available on Epithelial, digestive gland, tuft is intestine, bile and on stomach and in function on absorption and secretion. Based on experiment, we could find tubulus colurgens, epicubord, tubulus proksimal,and sirius capsolaris.
h.      In compact bone, there is a system called Haverst system. It consisted of Haverst duct, lamella, lacunae, and canaliculi. Based on experiment, compact bone has haverst system. Haverst system consist of lamella that arranged round the channel, in the middle of it there are artery and nerve.
i.        In nerve tissue,we have observed cerebellum. Nervous tissue composed of nucleus in the middle of cell body, cell body contained of nucleus and nucleolus, dendrite to forwarded nerves impulse to cell body, axon to continued the nerves impulse from cell body to the other side, neuron cell that has myelin sheath as protector.
j.        In blood tissue, blood diide into erythrocyte and leukocyte. Erythrocyte is a major part of the blood cell,contained hemoglobin and formed in back bone marroow. While leukocyte divide into lymphocyte, monocyte, basophile, and neutrhophile. Based on experiment with 10x10 magnification, we can find the erithrocytes in the blood tissue. Based on experiment, heart muscle is woolly its bounds, its form is elongated and available branch, on cytoplhasma exists brightness region and no moon so impressed striated, in essentials a lot of intermediated by cell, it activity was regarded by nerve autonomous, work rapid fire, contraction isstrength and is not easily tire and its rhythmic ways of working. 
k.      Streated muscle consisted of many fibers, and each of it has nucleus in the edge. Based on experiment,streated muscle has many nucleus and located in edge of the cells. Streated muscle has log form and it one of its characteristic.
l.        Non striated muscle consisted of many muscle fibers that have a shape like a spindle, long, slim, and has nucleus in the middle. Based on experiment, we could see the nucleus and fibers clearly.









CHAPTER V
CONCLUSION AND SUGGESTION
A.    Conclussion
Based on experiment, tissue plants divedied in younger tissues (meristem), it always split to add the size of plants. Adult tissue are, epidermis, parenchymal, transport, and cork. Epidermis is protect tissue of plant, parenchymal is base tissue of plant, transport tissue can devided into ploem and xylem. The funtion of phloem is transport product of photochyntesis, and xylem is transport mineral and important substance from root to the other parts.
Animal tissue devided be,  epithelial as protect tissue, nerve tissue as impuls conduct, blood tissue that important for circulation system, muscle tissue that consist streated muscle, cardica muscle, and smooth muscle.
B.     Suggestion
1.      Laboratory should prepare well the tools which will be used in experiment.
2.      In doing an experiment we must be careful when use the tools to avoid the accident which probably will happen. We must observe the object carefully and seriously so that we can find a good result.
3.      The assistant should give command so we can miss the mistake while doing the experiment.
