Question

What happens when the stomata on a plant's leaves are open?
I think it is A or B, verify?

A - Oxygen and water escape the leaves and carbon dioxide enters it.
B - Water enters the leaves and carbon dioxide escapes from the leaves.
C - Sunlight is able to enter the leaves and photosynthesis takes place.
D - Sugars and nutrients are transported up to the leaves from the roots.

Answer 1

The answer is A, water enters threw the roots not the leaves

Answer 2

The correct answer is A. Oxygen and water escape the leaves and carbon dioxide enters it.

Explanation:

In plants, stomata are small structures that are essential for the process of photosynthesis as well as other functions. Indeed, stomata open to absorb carbon dioxide that is used for photosynthesis; also, these open to release oxygen, which is one of the products of photosynthesis. Besides this, stomata regulate the amount of water in the plant as they open to release water or close if the water is scarce. This implies when stomata open carbon dioxide enters, while oxygen and water are released (option A).
