The root is a cylindrical plant organ, typical of higher plants, equipped with positive geotropism and whose principal functions are the absorption of water and nutrients and setting the plant to the substrate. No buds and leaves, allowing differentiation of the stem. Although it provides several characters for the identification, is essential to define the annual or perennial habit of a plant (a task which still has roots involves some difficulty). In all roots can be distinguished parts:

1. Neck or junction of the stem.

2. Branching zone, where secondary roots originate.

3. Root hair zone.

4. Growth zone.

5. Apical area protected by the cap or tip cap

There are different types of roots, which can be defined based on their origin

1.
embryonic roots
2. Real caulogenic

3. Real Adventice

For morphology and function, they differ:

1. Swinging: the main root is more developed than the secondary. (Medicago, Plantago)

2. Napiforme: thickened taproots by the storage of reserve materials (Daucus).

3. Fasciculate: there is no main root, the secondary form a hair (Poaceae).

4. Tuberous: all those booklets are thickened by the storage of reserve materials (Dalia).

The stem is among the flowering plants, shaft, usually air, extending the root and have the buds and leaves. Usually branches in various fields.

root is distinguished by the presence of knots that are inserted in the auxiliary buds and leaves, by the absence of terminal cap and its structure. The transition between root and shoot is done in the "neck." There may be underground stems and aerial roots there.

On the mode of growth and branching, the stem determines the size of the plant also has a supporting role in the plant and transport of nutrients between roots and leaves.

A stalk is composed two main areas:

comprises a lining of primary origin: the epidermis. The latter is composed of a single layer of cells lined up next to each other, you can see the occasional stomata to allow gas exchange between the external environment and the stem.

Under the epidermis is the cortical parenchyma, a tissue composed of cells thicker and less organized. It is where photosynthesis takes place and can serve as backup to the plant. Often lignified parenchyma below that serves as support to the plant, is the sclerenchyma.

central cylinder
The boundary between the cortex and central cylinder is bounded by the conductor axes. The latter are found in other parenchymal called medullary parenchyma. The beams are composed of two types of vessels, the xylem and phloem sap xylem conducts water and made crude minerals from the roots to the photosynthetic organs where the sap is sugar load. Then becomes elaborated sap which is driven by the phloem to the bodies energy demand, such as buds, roots, tubers, flowers, fruits ...

In the center of the stem is the pith or medulla containing parenchymal reserve. Among the Poaceae (grasses), this area is replaced by a central vacuum. This explains why the wheat stem is hollow when cut

sheet is one of the most important parts of the plant since it is part of the plant that is mandated to perform the function photosynthesis, respiration and and plant transpiration.

SHEET: PARTS

There are many types of leaves that distinguish some other plants, but essentially, every leaf is formed by the parts:
The limbus is the wide portion of the sheet. Is its most colorful and most people understand and identify as a sheet when you mention its name. In the limbo

we talk about:

- beam: The top of the page. Usually bright green.

-The back: It is the opposite to the beam. Its color is usually darker hair and features many times.

-Losnervios: they are a kind of wrinkles or channels that run along the leaf blade. In fact, drivers are the vessels that run along its surface.


-The outline: This is the margin or edge of the blade. Can be of different shapes that used to distinguish from other leaves.

The petiole is the leaf that joins the blade to the branch. It is shaped tail, and through it, run the conducting vessels. There are some pages that have no petiole. These leaves without petiole are called sessile.
