BIOMOLECULES AND ENZYMES

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: -You’ll recall that the apical meristem is the site of cell division and new cell production at the tips of the plant stems and roots. The cells that make up the meristem are undergoing mitotic cell division to produce more cells. These new cells result in growth and development of plant tissues.

Detailed explanation-3: -The Root Apical Meristem (RAM, for short) Just below the tip of the root, there is a region of small, densely packed cells that are actively dividing. These cells make up the RAM. To the outside (below, in your slide) of the root tip, the RAM cells produce an ephemeral tissue called the root cap.

Detailed explanation-4: -Meristems form anew from other cells in injured tissues and are responsible for wound healing. Unlike most animals, plants continue to grow throughout their entire life span because of the unlimited division of meristematic regions.

Detailed explanation-5: -Meristematic cells are also responsible for keeping the plant growing. The Shoot Apical Meristem (SAM) gives rise to organs like the leaves and flowers, while the Root Apical Meristem (RAM) provides the meristematic cells for the future root growth.
