Question

what is the main function of cellulose in plants?
a. capture water and sunlight
b. provide physical support
c. convert sunlight into carbohydrates
d. provide water and oxygen

Explanation:

Cellulose is a major component of the plant - cell wall. It gives rigidity and strength to plant cells, providing physical support to the plant structure. It is not involved in capturing water and sunlight (which is more related to structures like leaves), converting sunlight into carbohydrates (photosynthesis in chloroplasts), or providing water and oxygen directly.

Answer:

B. Provide physical support
