Concept explainers
Introduction:
The roots are mostly the first structure to arise from a seed. It is involved in the absorption of minerals and water from the soil for transportation to the other parts of plants. The structure of the root is composed of a root cap that has parenchyma cells for the protection of root tissue during its growth.
Answer to Problem 7STP
Correct answer:
The correct answer is option (C) protect root tissue as the root grows.
Explanation of Solution
Explanation/justification for the correct answer:
Option (C)protect root tissue as the root grows. The root cap forms a slimy compound that is found in the outside layer of the cell. This protects the root tissue from wear and tear in the ground asthe root grows. So, the correct answer is option (C).
Explanation for incorrect answer:
Option (A) generate new cells for root growth.The root cap has cells that divide to produce new roots. So, this is an incorrect option.
Option (B)help the root tissues absorb water. The water absorption is carried out by the root hairs.So, this is an incorrect answer.
Option (D) provides support for the root tissue. The mesophyll and the epidermal cells found in the roots are involved in the support of root tissue. So, this is an incorrect answer.
