Question

How does carbon dioxide enter the leaf?

Answer 1

Answer:

The carbon dioxide enter a leaf through stomata

Answer 2

Only the open stomata allow oxygen created during photosynthesis to leave the leaf.

Explanation:

• Green plants use CO2 from the atmosphere to perform photosynthesis. The stomata on the plant's surface allow carbon dioxide to enter the leaves.
• A pair of guard cells encircles each stomatal pore. Only the guard cells have control over the opening and closing of stomata pores.
