What will happen if the root tip is injured?

If the root tip is injured, the plant will not grow with the rate with which it was growing.

Explanation:

i. If the root tip is injured the root will not be able to penetrate in the soil easily. If the penetration of the root in the soil is not done properly, the root will not be able to absorb the required nutrients from the soil and provide them to the plant for healthy growth.

ii. If the plants do not get the required nutrients, its growth will be affected.
