Question

Root hair develop from:
A. Zone of cell maturation
B. Zone of cell elongation
C. Zone of mature cells
D. Zone of cell maturation

Answer 1

Hint: A root hair is a tubular outgrowth of a trichoblast, a hair-forming tissue on a plant root's epidermis. The area at the top of the root is closest to the plant.

Complete step by step answer:
Root hairs are structures that play a key role in the absorption of water and minerals. Root hair develops from the zone of cell maturation in root cells. These cells will divide and elongate till they form protruding processes and then differentiate by developing guard cells that cover the entire surface. Root hair development starts when the second mitotic division occurs and it is completed by the third mitotic division when they form out of elongated cells. The root hairs absorb a lot of water. They are long and can penetrate between soil particles, preventing dangerous germs from entering the plant via the xylem arteries.
The maturation zone is near the top of the root or closest to the plant. The root cap is the cap at the end of the root. A plant cell will begin in the cell division region and then migrate to the elongation region. A cell will elongate in this zone before moving on to the zone of maturation. Root hair cells are outgrowths at the root tips of plants.
As a result, the right answer is 'A.'

Note: Cell division occurs during the maturation zone. It is the zone in which cells determine their role in the plant's root system. Cells transform into parenchyma cells to store and transmit nutrients. Alternatively, they generate sclerenchyma cells, which contribute to the cell wall. Cells differ depending on their level of differentiation and maturation within the cell wall.
