Question

What is the advantage of a root cap covering the apical meristem of a root?

a) Protection from mechanical damage
b) Facilitating water absorption
c) Enhancing photosynthesis
d) Aiding in gas exchange

Answer 1

The root cap provides protection, facilitates water absorption, and aids in the smooth growth of the root.

Step-by-step explanation:

The root cap, which is a layer of protective cells covering the apical meristem of a root, provides a number of advantages:

1. Protection from mechanical damage: The root cap helps to protect the delicate apical meristem from being damaged as the root tip pushes through the soil.
2. Facilitating water absorption: The root cap increases the surface area of the root for better absorption of water and minerals from the soil.
3. Providing lubrication for the growing root: The root cap secretes a slimy substance that helps the root to move smoothly through the soil as it grows.
