The number, shape and internal structure of mitochondria:
Correct answer: C. Vary widely
- A. Vary slightly
- B. Do not change
- C. Vary widely
- D. Are identical
Explanation
The correct answer is that the number, shape, and internal structure of mitochondria vary widely. This variability allows mitochondria to fulfill the specific energy requirements of different cell types and adapt to changing metabolic conditions. The incorrect options suggest either minimal variation or uniformity, which does not reflect the dynamic nature of mitochondria. Their ability to change is crucial for efficient energy production and cellular adaptation.

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.
