Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What is the main purpose of a root cap?
A
to make sugars for the plant
B
to obtain carbon dioxide for photosynthesis for the plant
C
to increase the surface area available for water and mineral absorption
D
to protect the end of the growing root as it burrows through soil during growth
Explanation: 

Detailed explanation-1: -The root cap, a small tissue at the tip of the root, protects the root from environmental stress and functions in gravity perception.

Detailed explanation-2: -Roots grow in length only from their ends. The very tip of the root is covered by a thimble-shaped root cap, which serves to protect the growing tip as it makes its way through the soil. Just behind the root cap lies the apical meristem, a tissue of actively dividing cells.

Detailed explanation-3: -Complete answer: Root cap protects the growing root tip of plants and control of geotropic movement. The purpose of the root cap is to enable the downward growth of the root cap. The root cap is covering the sensitive tissue within the root cap. It also plays an important role in communication with the soil microbiota.

Detailed explanation-4: -It protects meristem against injury and provides lubrication for the growing root to dig through soil.

Detailed explanation-5: -The main function of the root cap is to protect the apical meristem and the structures of the root tip. This protective function is important for the primary growth of a plant.
