Instructions
Study each question carefully, then select the best answer. Answers with explanations are provided at the end.
1. Which of the following is the basic unit of all living organisms?
A. Tissue B. Organ C. Cell D. Organism
Answer: C. The cell is the basic structural and functional unit of life.
2. Which organelle is known as the “powerhouse of the cell”?
A. Nucleus B. Ribosome C. Chloroplast D. Mitochondrion
Answer: D. Mitochondria produce energy (ATP) through cellular respiration.
3. A student examines two cells under a microscope. Cell A has a cell wall and chloroplasts. Cell B has no cell wall. Which of the following is correct?
A. Cell A is an animal cell and Cell B is a plant cell B. Cell A is a plant cell and Cell B is an animal cell C. Both cells are plant cells D. Both cells are animal cells
Answer: B. Plant cells have cell walls and chloroplasts; animal cells do not.
4. Which of the following is NOT found in an animal cell?
A. Nucleus B. Mitochondria C. Cell wall D. Cell membrane
Answer: C. Cell walls are found in plant cells, not animal cells. Animal cells have only a cell membrane.
5. What is the function of the nucleus in a cell?
A. To produce energy for the cell B. To control all cell activities and contain the genetic material C. To carry out photosynthesis D. To transport materials within the cell
Answer: B. The nucleus is the control centre of the cell and contains DNA.
6. A plant cell is placed in a very salty solution. What will most likely happen?
A. Water enters the cell and it becomes turgid B. Water leaves the cell and it becomes flaccid or plasmolysed C. The cell wall dissolves D. The cell undergoes mitosis
Answer: B. Water moves out of the cell by osmosis (from low to high solute concentration), causing the cell to lose its turgidity.
7. Which of the following best describes diffusion?
A. Movement of water through a semi-permeable membrane B. Movement of molecules from high concentration to low concentration without using energy C. Movement of molecules using energy from ATP D. Movement of molecules from low concentration to high concentration
Answer: B. Diffusion is passive movement of molecules from high to low concentration.
8. What does the chloroplast contain that makes it appear green?
A. Haemoglobin B. Melanin C. Chlorophyll D. Cellulose
Answer: C. Chloroplasts contain the green pigment chlorophyll, which captures light energy for photosynthesis.
9. Which of the following is the correct order of organisation from simplest to most complex?
A. Organ → Cell → Tissue → Organism → Organ system B. Cell → Organ → Tissue → Organ system → Organism C. Cell → Tissue → Organ → Organ system → Organism D. Organism → Organ system → Organ → Tissue → Cell
Answer: C. The correct order from simplest to most complex is: Cell → Tissue → Organ → Organ system → Organism
10. What is the role of the cell membrane?
A. To produce energy for the cell B. To control the movement of substances into and out of the cell C. To store food and water D. To carry out photosynthesis
Answer: B. The cell membrane is selectively permeable and controls what enters and leaves the cell.
11. Which of the following correctly distinguishes a prokaryotic cell from a eukaryotic cell?
A. Prokaryotes have a nucleus; eukaryotes do not B. Prokaryotes do not have a nucleus; eukaryotes do C. Prokaryotes are larger than eukaryotes D. Prokaryotes have chloroplasts; eukaryotes do not
Answer: B. Prokaryotic cells lack a distinct nucleus; their DNA floats freely in the cytoplasm. Eukaryotic cells have a nucleus enclosed by a membrane.
12. A student soaks a raisin in water overnight. In the morning, the raisin has swollen up. Which process explains this?
A. Diffusion B. Active transport C. Osmosis D. Evaporation
Answer: C. Water moved by osmosis into the raisin from the surrounding water (from low solute concentration outside to high solute concentration inside the raisin).
13. Which organelle is responsible for making proteins in the cell?
A. Golgi apparatus B. Ribosome C. Vacuole D. Endoplasmic reticulum
Answer: B. Ribosomes are the site of protein synthesis in the cell.
14. What is the main function of chloroplasts in plant cells?
A. To produce energy through respiration B. To manufacture proteins C. To carry out photosynthesis using light energy D. To control cell division
Answer: C. Chloroplasts use light energy, water, and carbon dioxide to produce glucose through photosynthesis.
15. A cell has the following features: no cell wall, no chloroplasts, has a large irregular shape, and contains mitochondria. What type of cell is it most likely to be?
A. A leaf cell from a mango tree B. A human muscle cell C. A root hair cell of a bean plant D. A bacterial cell
Answer: B. A human muscle cell is an animal cell with no cell wall or chloroplasts. It would be irregular in shape and contain many mitochondria to provide energy for muscle contraction.
