Sample practice questions
Easy
1. Which structure is present in plant cells but absent in animal cells, providing rigidity and shape?
Cell wall
Cell membrane
Nucleus
Mitochondria
Answer: Cell wall — Plant cells have a rigid cell wall (made mainly of cellulose) surrounding the cell membrane, which animal cells lack entirely.
Easy
2. Which organelle is described as the "powerhouse" of the cell, producing energy through cellular respiration?
Answer: mitochondria — Mitochondria are the site of cellular respiration, producing the energy (ATP) the cell needs to function, and are often called the "powerhouse" of the cell.
Medium
3. Which organelle, found in plant cells but not animal cells, is responsible for photosynthesis?
Chloroplast
Mitochondrion
Nucleus
Cell membrane
Answer: Chloroplast — Chloroplasts are the organelles responsible for photosynthesis, converting light energy into chemical energy, and give plants their green colour; animal cells lack chloroplasts entirely.
