The correct answer is:
C. Carbon(IV) oxide
Explanation:
In plants, the main excretory product of respiration (a metabolic process) is carbon(IV) oxide (COâ‚‚).
It is produced during aerobic respiration, especially in the absence of light, and is released through stomata.
What about the other options?
A. Oxygen:
It's actually a by-product of photosynthesis, not metabolism/excretion from respiration.
B. Alkaloids:
These are secondary metabolites, not main excretory products.
D. Mucilage:
It's used for storage, protection, or water retention, not excretion.
Final Answer:
C. Carbon(IV) oxide
