The question is incomplete as it does not have the options which are:
A. Phloem
B. Xylem
C. Apical meristem
D. Root cap
Answer:
The correct answer will be option- Root cap
Explanation:
The plant growth takes place not only above the surface but below the surface also in the roots. Roots continually grow to absorb more water and nutrients to support the growth of the plant.
The roots are protected by a layer of protective cells forming a structure called root cap below the root. The root cap protects the roots, secretes a substance which helps the growth of the root and the sense gravity.
In the given question since the roots are not able to grow therefore the damaged part will be the root cap.
Thus, the root cap is the correct answer.
