- By producing oxygen and sequestering carbon dioxide
- By breaking down glucose into carbon dioxide
- By storing carbon in the vacuole
A: By producing oxygen and sequestering carbon dioxide

Q: Why is understanding plant hormones important for studying plant growth?
- They are the only factors affecting plant size.
- They regulate growth and development in response to environmental stimuli.
- They are not relevant to plant biology.
- They only affect flowering plants.
A: They regulate growth and development in response to environmental stimuli.

- In the cytoplasm
- In the thylakoid membranes
- In the nucleus
A: In the thylakoid membranes

Q: How does human activity impact plant biodiversity?
- It has no effect on plant communities.
- It can lead to habitat destruction and decreased resilience.
- It solely benefits plant growth.
- It increases the number of plant species.
A: It can lead to habitat destruction and decreased resilience.

Q: Which of the following is an advantage of asexual reproduction in plants?
- Increased genetic diversity
- Ability to produce genetically identical offspring quickly
