Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
As the number of ____ increases, the surface area also increases, and the plant absorbs more water and minerals.
A
Root cap
B
Root hair
C
Root tip
D
Root cells
Explanation: 

Detailed explanation-1: -Root hairs are the small tubular extensions of the root surface which help in the absorption of water and minerals from the soil. It increases the surface area for absorption. More number of root hairs will increase the surface area and increase water absorption also.

Detailed explanation-2: -Root hairs collect water and minerals that are present in the soil. They also increase the surface area for absorption.

Detailed explanation-3: -Because they vastly increase the root surface area and effectively increase the root diameter, root hairs are generally thought to aid plants in nutrient acquisition, anchorage, and microbe interactions (Cutter, 1978; Hofer, 1991).

Detailed explanation-4: -Root hairs are the structures which increase the surface area of absorption of water and minerals. They are delicate and very fine, thread-like structures, which arise from the region of maturation of the root.

Detailed explanation-5: -Root hairs greatly increase the root surface area and therefore increase the ability of a plant to absorb water and nutrients.
