Options:
A. Stomata
B. Chloroplast
C. Mesophyll
D. Vascular bundle

Correct Answer: B. Chloroplast

What is the byproduct of the light-dependent reaction of photosynthesis?

Options:
A. Water (H₂O)
B. Carbon dioxide (CO₂)
C. Oxygen (O₂)
D. ATP

Correct Answer: C. Oxygen

Oxygen is released during the light-dependent stage of photosynthesis when water is split.

Question:
What is the internal change that a seed undergoes before germination?

Options:
A. After-ripening
B. Dormancy
C. Sprouting
D. Fertilization

Correct Answer: B. Dormancy

Dormancy is a temporary inactive period where seeds remain inactive before the conditions become favorable for germination.

Question 7: Bryophytes vs. Pteridophytes

Question:
Which statement is correct regarding bryophytes and pteridophytes?
