Answer:

TRUE

Explanation:

Answer 2

Guard cells control the opening and closing of stomata

Explanation:

• This is a TRUE statement.

• Gas exchange takes occur through stomata, which are tiny pores on the leaves.
• For photosynthesis, a large amount of gas enters and leaves the cell.
• When photosynthesis is not taking place, the stomata are closed, preventing water loss from the leaves.
• The guard cells that surround the stomata control the opening and closing of the stomata.

• When water enters the guard cells and the pore opens, the guard cells enlarge. When the guard cell shrinks, the pore closes as well.
