Question

Root hair develop from

• A. Zone of cell maturation
• B. Zone of cell elongation
• C. Zone of mature cells
• D. Zone of cell formation

Answer 1

The correct option is A Zone of cell maturation

The region of maturation is located at the top of the root, or closest to the plant. The end of the root is known as the root cap. A plant cell will begin in the region of cell division, and then travel to the region of elongation. In this zone, a cell will elongate and then travel to the zone of maturation. Root hair cells are outgrowths at a tip of the plant's roots. They are found only in the zone of maturation, and not the zone of elongation, possibly because any root hairs that arise are sheared off as the root elongates and moves through the soil.

So, the correct answer is 'A'.
