NEET BIOLOGY

Detailed explanation-1: -apical meristem, region of cells capable of division and growth in the root and shoot tips in plants. Apical meristems give rise to the primary plant body and are responsible for the extension of the roots and shoots.

Detailed explanation-2: -There are two main meristems in plants, the shoot apical meristem (SAM) generating above-ground tissues and organs and the root apical meristem (RAM) giving rise to the primary root of the plant.

Detailed explanation-3: -Root and shoot apical meristems are found at the tips or growing apex of roots and shoots in plants, respectively. They are primary tissues. The cells of the shoot and root apical meristems divide rapidly. Moreover, they are indeterminate or undifferentiated cells.

Detailed explanation-4: -There are three primary meristems: the protoderm, which will become the epidermis; the ground meristem, which will form the ground tissues comprising parenchyma, collenchyma, and sclerenchyma cells; and the procambium, which will become the vascular tissues (xylem and phloem).

Detailed explanation-5: -Apical meristem is present at the growing tips of stems and roots. Its main function is to trigger the growth of new cells in young seedlings at the tips of roots and shoots and forming buds.
