STRUCTURE AND FUNCTION BODY PLANT.

STRUCTURE AND FUNCTION BODY PLANT.

Organs had by high level plant is root, bar, and leaf. Despitefully there is other important organ which owned by plants that is flower. Flower can round into seed and fruit. However, do not all high level plants have flower, for example nail;axis plant. Flower organ only owned by plant which including bloomy plant group ( Anthophyta).
Root
Root is part of functioning plant permeate mineral and water from within land. Most plants have root staying in ground. At high level plant group there is two root system, that is root system ride and fiber root system. See picture below. Crop root at the picture have king sized shares is so-called especial root. And around him, grow small root as root branch or referred as root beside. this Root system is referred as root ride. Root ride is primary root and especial root able to grow to continue and can long and big. Especial root share to take care of the straighten of plant.
See picture below, do not especial root there are part of big root. this Root system is referred as fiber root. Root grow in bar jetty area. This root of measure of smaller than especial root and many branchs like fiber. Fiber root grow to disseminate around crop and function to collect water of enough area wide. Fiber root generally there are at plant of monokotil, for example at plant of of grass. While root system ride the him of there are at plant of dikotil, legume the example, mango, carrot.

Fiber root generally there are at plant of monokotil, for example at plant of of grass. While root system ride the him of there are at plant of dikotil, the example, mango, carrot.




Root Structure
Root structure consist of out structure (morfologi) and in structure (anatomy).

External of structure
External of Structure root for example consisting of hair grow on and root veil (kaliptra).
Hair Grow
Hair grow on is gibbosities is elongation of epidermis cells. Hair grow on is generally formed in area of near by back part grow on and only short-lived.
Kaliptra
At the end of root there are network of meristem. This network cells of always split lah. Tip of network of meristem this under the aegis of root veil ( kaliptra). Functioning Kaliptra protect cells grow on from damage of effect growth of root penetrate land.
Dot Grow and Precise elongation area
Rear veil grow on there are dot grow. Cells dot area grow active split . Rear dot area grow there are long cells and have big vakuola. This is elongation area.

In Structure
In Structure successive root from outside into according to athwart slice is epidermis, cortex, endodermis, and center cylinder.
Epidermis
Cells surface of root form epidermis coat which the was cell formation is equal to bar cell. Cortex side in epidermis formed by ring which consist of cells of parenkim, that is cortex. Functioning cortex as food reserve.
Endodermis
In side in cortex there are network of endodermis consist of to endue thick cell which limit cortex coat. cell of Endodermis have part of like ribbon of so-called ribbon of Kaspari . Ribbon of Kaspari this function to hinder the passing of dilution from within land through cell wall, so that dilution emit a stream of passed sitoplasma. Besides endodermis also function to arrange in and out materials him from and to root network.
Cylinder center
In side in endodermis there are center cylinder. pregnant Center cylinder of small channel bundles and perisikel, that is xilem and floem.Perisikel there are in around center cylinder. At this perisikel of young root there are network of xylem network and of floem. At plant of monokotil, situation of xilem at intervals with floem. situation of Xilem in side in from floem. While at plant of dikotil, binding small channel of and xilem of floem beastly, situation of xilem in side in situation of floem. At older root there are cambium among and xilem of floem.


Root of function
To enter into mineral salt and water.
Putting down plant to the ground, or function as " yoke" for plant.
Assisting respiration.
To make keep frood.

Bar
Bar is shares which contributing plant body. Functioning bar transport food-stuff.
Structure Bar
Structure bar consist of external structure and structure in. External structure at differentiated high level plant to become plant structure have wood to and plant structure do not have wood ( herba). While depth structure consist of part of epidermis, cortex, endodermis, and center cylinder.

External of structure
Bar Plant have wood to have hard characteristic, thick, and long lived. Surface of hard bar and in selected shares there are lentisel. Lentisel relate to bar interior and function as place transfer of gas in bar. At plant bar have wood to which still young there are chlorophyll, so that can do photosynthesis.
Plant of Herba, for example water girlfriend, bar of softening. This matter is caused by wood network inexistence at plant of herba.
In structure
Interior bar consist of epidermis, cortex, endodermis, and center cylinder.
Epidermis
Wall epidermis cell at rather thick bar and arranged in layers by cuticle. functioning Epidermis bar coat protect coats in it.
Cortex
In coat side in epidermis there are cortex coat which the was cell of globular and have flimsy wall . Functioning cortex as place supply of food for bar.
Endodermis
Coat of endodermis located in side in cortex coat. coat of Endodermis at bar do not clear so and hamper one with cortex coat.
Cylinder center
Cylinder center is the inner end of bar. In cylinder center there are small channel of wood ( xilem), small channel filter ( floem), and cyperus microiria. Xilem consist of tubes which is have functioning thick wall to transport mineral salt and water of root to leaf.
Floem in form of tube owning small pore in his base, so that like filtering ( filter) the functioningness transport result of photosynthesis of leaf to entire plant shares.
Bundle small channel bar of dikotil
bar of dikotil, binding the small channel of situation of beraturan form circle. There are small channel of wood of xilem and of floem. Among and xilem of floem there are cambium.

Bundle small channel of bar of monokotil
At plant bar of monokotil, binding small channel disseminate irregular and do not have cambium.

Function Bar
Bar is trajectory place organ irrigate and mineral salt of root to leaf, and also trajectory place result of photosynthesis ( food gist) of leaf to other shares of plant.
Leaf
Leaf located in plant tabletop and stick at bar. Leaf is place the happening of photosynthesis process, that is process of food at greenery.
Structure Leaf
Leaf in form of wide pipih and green chromatic. Leaf sustained by leaf handle. Leaf handle relate to leaf bone. Leaf bone of granch small channel of forming nets transport.
External of Structure
Leaf in general in form of wide and green chromatic. Green colour because of chlorophyll which there are in kloroplas. Kloroplas is small structure of green chromatic which there are in leaf cell sitoplasma. multifarious Leaf form of manner. Some plant types, like, pine, having leaf in form of needle. Cactus plant have leaf in form of thorn or shell. At sheet surface of leaf there are leaf blood-vessel or bone. Bone leaf form there is which is fin, for example mango leaf. There is which is finger, for example papaw leaf, there is bony of parallel tortous leaf, for example maize leaf. leaf have Type to finger and fin generally there are at plant of dikotil. On the contrary, parallel tortous leaf bone habit found at plant of monokotil.

Besides, immeasurable leaf edge also, there is which in form of flattening for example jackfruit leaf and there is also which do not flat(serrated), for example rose leaf.
Leaf formation differentiated of single leaf and leaf of compound. Leaf referred as single leaf if one leaf handle only there are a piece of leaf. If one leaf handle there are some piece of leaves, the leaf named leaf of compound.
In Structure
In structure or anatomy in leaf consist of epidermis, pillar network ( palisade), and rock flower network ( spons).

Epidermis
Epidermis leaf is single cell coat on the surface of upper and lower leaf. Epidermis arranged in layers by flimsy coat of candle is so-called cuticle. Cuticle cause waterproof epidermis so that lessen the loss of water. At epidermis under generally there are stomata.
Pillar network ( palisade)
Below epidermis to the there are network of palisade. cells of Palisade generally length and lapped over meeting like pillar line. At network cells of palisade many there are kloroplas concidering chlorophylls and here lah process photosynthesis take place.
Flower rock network ( spons)
At flower network compose there are small channel transport which in the form of leaf bone. Conveyor network consist of and xilem of floem.
Function Leaf
Place photosynthesis of place transfer of photosynthesis gassaat, respirasi, and transpirasi.

Flower
Flower come from result modify leaf. Do not all plants have flower. For high level plant which have flower, flower are important organ because the plant regenerasi started from flower.

Structure Flower
Flower have multifarious colour and form manner depend on species or his type. However, flower at plant have is same Elementary structure. Flower structure consist of calyx, crown, stamen, and pistil.

Flower calyx
External Shares kalik of flower is calyx. Calyx in general green chromatic, despite of gorgeous also. Functioning calyx protect flower interior.
Corolla
Corolla located in side in calyx. Corolla in general have multifarious colour and form of manner and function to draw insect of powder.

Stamen
Stamen at flower share as masculine genitals. Stamen consist of gist head and gist handle.

Pistillum
Pistillum consist of the parts of pistil head, pistillum handle, will seed ( ovul), ovary ( ovari), and egg cell ( ovum). Pistil share as female genitals.

Flower Function
Function of flower is as a means of propagation generatively at plant. Function of differ from flower is as a means of ornament. Appliance ornament of flower consist of crown and calyx.
Fruit
At the him of fruit expand from pistillu. Pistillum consist of pistil head, pistil handle, and ovary.

Real fruit and sham fruit
Ovary will round into fruit and seed will will become seed if happened impregnation. If fruit formed by all network at just ovary, hence the fruit of referred as real fruit. Mango the example, papaya, fruit, tomato, rice. There is fruit the formed is not from just ovary, but also come from parts of the differ from flower. That fruit is referred as sham fruit. Pineapple the example, formed of flower leaves and ovary ( calyx), monkey guava or guava mede, formed of big flower handle, apple, coming from puffy flower base.
Parts of flower
Fruit lapped over of seed, kernel, and fruit skin. At fruit which not yet cooked, fruit skin do not experience of dissociation of network. But fruit which have cooked, husk there is which differentiated become 3 coat, that is
1. External coat ( epikarp) the hardness for example
coconut.

2. Middle coat ( mesokarp) the thickness and fleshly, or stringy, for example papaya and mango.

3. Coat in ( endokarp) there is which in the form of hard cell coat, there is also which in the form of hard or flimsy
Seed
Seed is especial propagation appliance for seed plant ( Spermatophyta) because containing new plant candidate which have 3 bodywork that is seed husk, endosperma, and embryo. Seed is part of plant which in form of from impregnation result that happened in ovary. In ovary there are seed will and in seed will there are new individual candidate or embryo which ready for germinating. Embryo or new individual candidate have shares as follows.
1) Root institute or radicle ( radikula)
2) Leaf institute or cotyledon, first leaf at plant, having
Appliance photosynthesis function before leaf was truthfully formed.
Place pile up food
3) Institute bar, there is which the was bar internode of above institute leaf, there is which the was bar internode of below institute leaf.
Individual candidate just wrapped by 2 coat, that is interior and exterior.
Exterior referred as seed husk.
Referred as Inner also endosperma.

Seed owning endosperma, for example mango. There is also seed which do not have endosperma, for example peanut, haricot bean. Seed will there is 2 kinds of :
Seed will prepacked by fruit leaf for example mango.
Seed will which do not prepacked by fruit leaf, for example graceful tree Pakistan, tusa.
