NEET BIOLOGY

Detailed explanation-1: -Most plant growth occurs in two types of meristems. Primary growth occurs in apical meristems, located at the tips of roots and shoots. Secondary growth occurs in lateral meristems, which run along the lengths of roots and shoots.

Detailed explanation-2: -Meristems make unspecialised cells that have the potential to become any type of specialised cell. They are only found is certain parts of the plant such as the tip of roots and shoots and in between the xylem and phloem.

Detailed explanation-3: -They grow through a combination of cell growth and cell division (mitosis). The key to plant growth is meristem, a type of plant tissue consisting of undifferentiated cells that can continue to divide and differentiate. Meristem allows plant stems and roots to grow longer (primary growth) and wider (secondary growth).

Detailed explanation-4: -Plant growth occurs in areas called meristems, which are the site of repeated cell division of unspecialized cells. These cells differentiate and become specialized in relation to the function they will perform. There are two types of meristems: lateral and apical.

Detailed explanation-5: -Most primary growth occurs at the apices, or tips, of stems and roots. Primary growth is a result of rapidly-dividing cells in the apical meristems at the shoot tip and root tip. Subsequent cell elongation also contributes to primary growth.
