Which of the following cell type is most appropriate to study mitochondria?
Correct answer: B. Muscle cell
- A. RBC (Red Blood Cell)
- B. Muscle cell
- C. Mesophyll cell
- D. E.coli
Explanation
Muscle cells are highly active and require substantial amounts of ATP for contraction, which necessitates a high number of mitochondria. RBCs (red blood cells) in mammals do not contain mitochondria, as their primary function is to transport oxygen. Mesophyll cells, while involved in photosynthesis, do not have energy demands as high as muscle cells and therefore have fewer mitochondria. E.coli, being a prokaryote, lacks any membrane-bound organelles, including mitochondria.

About Cell Structure and Function
Animal, plant, prokaryotic and eukaryotic cells are compared through their membranes, cell walls, nuclei and cytoplasmic organelles. The work includes the structures and functions of mitochondria, chloroplasts, ribosomes, endoplasmic reticulum, Golgi apparatus and lysosomes, as well as chromosome organization and the distinction between chromatin and chromosomes.
