Free Animal and Plant Cell MCQs with Answers
275 Animal and Plant Cell MCQs from Biology, each with the correct answer and a written explanation of why it is correct. Free and unlimited, with no account needed.
Animal and plant cells share a plasma membrane, cytoplasm, nucleus, ribosomes, mitochondria and endoplasmic reticulum, but plant cells also have a cellulose cell wall, chloroplasts and a large permanent vacuole. Questions cover organelle structure and function, differences between the two cell types, and how membranes control movement of substances.

- A. Psilopsida
- B. Lycopsida
- C. Sphenopsida
- D. Pteropsida
Explanation: Lycopsida were the first vascular plant group to develop true leaves, called microphylls, which have a single unbranched vein.
Correct answer: Lycopsida- A. Mesophyll cells
- B. Xylem Cells
- C. Phloem Cells
- D. Guard Cells
Explanation: Guard cells are specialized bean-shaped cells that surround each stomatal pore and regulate gas exchange and water loss.
Correct answer: Guard Cells- A. Cell wall
- B. Cytoplasm
- C. Vacuoles
- D. Mitochondria
Explanation: A plant cell has a cellulose cell wall outside its plasma membrane, while an animal cell lacks a cell wall.
Correct answer: Cell wall- A. Cell Membrane
- B. Cell wall
- C. Cytoplasm
- D. Chromatin
Explanation: A cell wall is a rigid outer layer made mainly of cellulose and is characteristic of plant cells, whereas the cell membrane, cytoplasm and…
Correct answer: Cell wall- A. Parenchymatous
- B. Sclerenchymatous
- C. Chloroplast
- D. None of the above
Explanation: Interpreting “Febries” as “fibres,” plant fibres are sclerenchymatous cells with thick, lignified walls that provide strength.
Correct answer: Sclerenchymatous- A. Phloem
- B. Parenchyma
- C. Xylem
- D. None of the above
Explanation: Phloem transports organic food, mainly sucrose made during photosynthesis, from source tissues to growing or storage regions of the plant.
Correct answer: Phloem- A. Phloem
- B. Xylem
- C. Parenchyma
- D. Collenchyma
Explanation: Phloem is the living vascular tissue that transports sugars and other organic nutrients from sources such as leaves to consuming or…
Correct answer: Phloem- A. Necrosis
- B. Apoptosis
- C. Blood cancer
- D. All of these
Explanation: Apoptosis is programmed cell death, in which a cell is removed through a controlled sequence that usually avoids inflammation.
Correct answer: Apoptosis- A. herb
- B. tree
- C. grass
- D. None of these
Explanation: Banana is a giant herb because its apparent trunk is a pseudostem formed from tightly packed leaf bases, not a true woody stem.
Correct answer: herb- A. Shape
- B. Size
- C. Structure
- D. Fundamental organization
Explanation: Cells in an organism differ greatly in shape, size and specialized structures, but they share a basic cellular organization such as a…
Correct answer: Fundamental organization- A. Hydra
- B. Crabs
- C. Squids
- D. Earthworm
Explanation: Hydra is diploblastic because its embryo develops two germ layers, ectoderm and endoderm, separated by mesoglea.
Correct answer: Hydra- A. Rana tigrina
- B. Allium cepa
- C. Aspergillus
- D. None of these
Explanation: The scientific name of onion is Allium cepa, with Allium as the genus and cepa as the species name.
Correct answer: Allium cepa- A. Passive Transport
- B. Osmosis
- C. Active Transport
- D. Diffusion
Explanation: Active transport moves substances against their concentration gradient and requires energy, usually from ATP, through membrane transport…
Correct answer: Active Transport- A. Cell wall
- B. Cell membrane
- C. Boundary
- D. Nuclear envelop
Explanation: The nuclear envelope is a double membrane surrounding the nucleus and separating its contents from the cytoplasm.
Correct answer: Nuclear envelop- A. Suckers
- B. corms
- C. corals
- D. None
Explanation: Chrysanthemum can be propagated vegetatively by suckers, which are shoots arising from the base of the plant and capable of forming…
Correct answer: Suckers- A. Apoptotic bodies
- B. Necrosis bodies
- C. Tuberculosis bodies
- D. Cytokinetic bodies
Explanation: During apoptosis, the cell breaks into membrane-bound fragments called apoptotic bodies, which are then removed by phagocytic cells.
Correct answer: Apoptotic bodies- A. 20 to 35 billion cells
- B. 50 to 70 billion cells
- C. 10 to 20 billion cells
- D. 15 to 25 billion cells
Explanation: Apoptosis continuously removes approximately 50 to 70 billion cells per day in an adult, balancing the production of new cells and…
Correct answer: 50 to 70 billion cells- A. lysosomes
- B. Vacuoles
- C. Cytoplasm
- D. Golgi bodies
Explanation: During necrosis, damaged cells lose membrane integrity and lysosomal enzymes are released, digesting cellular components and surrounding…
Correct answer: lysosomes- A. Irregular in shape
- B. Convex in shape
- C. Long and cylindrical in shape
- D. Kidney-shaped
Explanation: In most dicot plants, guard cells are kidney-shaped and change their turgor to open or close the stomatal pore.
Correct answer: Kidney-shaped- A. Wind
- B. Insects
- C. Water
- D. Rain
Explanation: Wind-pollinated flowers commonly have long, flexible filaments with pendulous anthers so pollen can be shaken into the air.
Correct answer: Insects
