How do plant cells differ from animal cells in terms of energy production?
Plant cells use mitochondria only
Plant cells use chloroplasts for photosynthesis
Animal cells use chloroplasts for photosynthesis
Animal cells do not produce energy
Answer explanation
Plant cells differ from animal cells in energy production as they contain chloroplasts, which enable photosynthesis, converting sunlight into energy. Animal cells lack chloroplasts and rely solely on mitochondria for energy.

Which organelle is known as the "control center" of the cell?
Nucleus
Lysosome
Golgi apparatus
Vacuole
Answer explanation
The nucleus is known as the "control center" of the cell because it houses the cell's genetic material and regulates gene expression, thereby controlling cellular activities and functions.
