Question

which process is common to all cells? a. all cells allow organisms to move b. all cells perform photosynthesis c. all cells need and use energy d. all cells make their own food.

Explanation:

• Option A: Not all cells enable organism movement (e.g., plant root cells).
• Option B: Only photosynthetic cells (e.g., plant chloroplast - containing cells) perform photosynthesis; animal cells do not.
• Option C: All cells (prokaryotic, eukaryotic) need energy for functions like metabolism, and use processes like cellular respiration (or photosynthesis in autotrophs) to obtain/use energy.
• Option D: Heterotrophic cells (e.g., animal cells) do not make their own food; they obtain it from external sources.

Answer:

C. All cells need and use energy
