Which cells absorb carbon dioxide in the leaf?
Correct answer: C. Mesophyll cells
- A. Neutrophil cells
- B. Basophil cells
- C. Mesophyll cells
- D. All of these
Explanation
Option C is correct. Mesophyll cells are found in the spongy and palisade layers of the leaf, where they are responsible for photosynthesis and gas exchange. They absorb carbon dioxide from the intercellular spaces, facilitating its diffusion into the cells for use in photosynthesis.Option A is incorrect because neutrophil cells are part of the human immune system, not plants. Option B is incorrect because basophil cells are also part of the immune system. Option D is incorrect because it incorrectly suggests that all listed cells are involved in carbon dioxide absorption, which is not the case; only mesophyll cells fulfill this function in leaves.

About Bioenergetics
Cellular respiration explains how cells release energy from glucose through glycolysis, the link reaction, Krebs cycle and electron transport chain. It includes ATP production, substrate-level and oxidative phosphorylation, aerobic versus anaerobic respiration, and the roles of mitochondria, oxygen and fermentation in energy transfer.
