Question

2. Roots grow downward because
a. They have vascular bundles.
b. they grow opposite to the force of gravity.
c. they grow away from water sources. d. there are gravity-sensing cells in the root cap.

Answer 1

Answer:

It is essential for roots to grow down so they can explore the soil and maximise their water uptake. Scientists have long speculated that plants bend in response to gravity due to the redistribution of the plant hormone auxin in the tip of the root.
