ANATOMY OF THE PLANT ROOT

The root morphology is divided into four regions: root top, apical meristem, elongation zone and hair. The new root cap helps the root to penetrate the soil. As the roots get deeper, these roots fall out, creating a sticky surface that provides lubrication. Behind the root cap, the apical meristem produces new elongated root cells.

Next, hairs form on the roots, which absorb water and mineral nutrients from the soil. The first root of a seed-producing plant is the root, which After the seed germinates, it develops from the plant's embryo. During dissection, the root cell system consists of hairs from the root, epidermis, epidermis, cortex, endothelium, peripheral chakra and finally the vascular tissue in the center of the root, which carries the absorbed water. from the root to other part of the plant.

Buttercup root cross section Perhaps the most important feature that distinguishes roots from other parts of the plant (such as stems, twigs, and leaves) is that the roots are endogenous, that is, they are native. of the inner layer of the L axis, such as the circumflex .

In contrast, the stem and leaves are exogenous, meaning they develop from the outer layer of the cortex. In response to nutrient concentrations, roots also synthesize cytokinin, which serves as a signal for the rate of branch growth. The root's function is generally to store food and nutrients. The roots of most species of vascular plants form mycorrhiza symbiotically with some fungi and bacteria, including A large number of other organisms are also closely related to the roots.
