LIFE SCIENCE

Detailed explanation-1: -Apical meristems occur at the growing shoot and root tips (Figure 20.21). Root apical meristems produce the root cap, which consists of lubricated cells that are sloughed off as the meristem is pushed through the soil by cell division and elongation in more proximal cells.

Detailed explanation-2: -Cell division in plants occurs in regions called meristems . Cells of the meristem can differentiate to produce all types of plant cells at any time during the life of the plant. The main meristems are close to the tip of the shoot, and the tip of the root.

Detailed explanation-3: -The zone of elongation is where the newly formed cells increase in length, thereby lengthening the root. Beginning at the first root hair is the zone of cell maturation where the root cells begin to differentiate into special cell types.
