Answer:
- Carbon dioxide enters stomata
- Oxygen is released through stomata.
Step-by-step explanation:
The following statements describe interactions between substances and stomata during photosynthesis:
- Carbon dioxide enters stomata.
- Oxygen is released through stomata.
Carbon dioxide is needed for photosynthesis, while oxygen is a byproduct of photosynthesis.
The other statements are not correct:
- Hydrogen does not enter or leave stomata. Hydrogen is used in photosynthesis, but it is produced within the plant cell, not absorbed from the air.
- Oxygen does not enter stomata. Oxygen is a byproduct of photosynthesis, so it is released through stomata, not absorbed from the air.
Therefore, the correct answers are Carbon dioxide enters stomata. and Oxygen is released through stomata.
