Question

In plants, active absorption usually does NOT occur when ______.

विकल्प

• Stomata are open.

• Stomata are closed.

• Transpiration stops.

• It is night time.

Answer 1

In plants, active absorption usually does NOT occur when Stomata are open.

Explanation:

Active absorption in plants, which requires energy (ATP), typically occurs when transpiration is low, such as at night or when stomata are closed. When stomata are open (usually during the day), transpiration is high, and passive absorption via transpiration pull dominates.
