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. Active transport
- B. Passive transport
- C. Osmosis
- D. Diffusion
Explanation: Active transport is a mode of cellular transport that requires energy to move molecules or ions against their concentration gradient, from…
Correct answer: Active transport- A. Vacuole, Chloroplast, and ribosomes
- B. Chloroplasts, Microtubules, and peroxisomes
- C. Chloroplast, Cell Wall, and vacuole
- D. Chloroplast, Cell Wall, Mitochondria
Explanation: All mentioned organelles are absent in animal cells and are only present in plant cells hence this option is correct.
Correct answer: Chloroplast, Cell Wall, and vacuole- A. Proteins
- B. Cholesterols
- C. Cytoskeleton
- D. Phospholipids
Explanation: The fundamental structure of the membrane is the phospholipid bilayer, which forms a stable barrier between two aqueous compartments.
Correct answer: Phospholipids- A. Centrioles
- B. Rough Endoplasmic Reticulum
- C. Microtubules
- D. Ribosomes
Explanation: Centrioles are present in (1) animal cells and (2) the basal region of cilia and flagella in animals and lower plants (e.g.
Correct answer: Centrioles- A. Passive transport
- B. Active transport
- C. Facilitated diffusion
- D. Filtration
Explanation: Active transport requires the expenditure of energy in the form of ATP to move molecules against their concentration gradient, from an…
Correct answer: Active transport- A. Phospholipids
- B. Globular proteins
- C. Glycolipids and glycoproteins
- D. Cholesterol
Explanation: Glycolipids and glycoproteins presence are the basic factors for differentiating cells
Correct answer: Glycolipids and glycoproteins- A. Primary wall _ secondary wall _ middle lamella
- B. Secondary wall _ primary wall _ middle lamella
- C. Primary wall _ middle lamella _ secondary wall
- D. Secondary wall _ middle lamella _ primary wall
Explanation: The correct arrangement of cell wall layers in a plant cell is Secondary wall _ Primary wall _ Middle lamella.
Correct answer: Secondary wall _ primary wall _ middle lamella- A. Proteins
- B. Lipids
- C. Lipo protein
- D. Cellulose
Explanation: Lipids → mainly phospholipids, form the bilayer (structural framework).Proteins → embedded or attached, responsible for transport…
Correct answer: Lipo protein- A. Cellulose
- B. pectin
- C. Lignin

Explanation: Keratinized epithelium is a stratified squamous epithelium (consisting of flattened squamous cells arranged in layers upon the basal…
Correct answer: Skin- A. Primary cell wall
- B. Secondary cell wall
- C. Middle lamella
- D. Plasma membrane
Explanation: Cellulose is a crucial polysaccharide that forms the structural component of the primary cell wall in plants.
Correct answer: Primary cell wall- A. Waldyne
- B. T.H. Margan
- C. Robert Brown
- D. Kohler
Explanation: The correct answer is Robert Brown, who discovered the cell nucleus in 1831 while examining plant cells under a microscope.
Correct answer: Robert Brown- A. Catalase
- B. Lipase
- C. Permease
- D. Arginase
Explanation: The correct answer is Permease, which is a protein carrier in the plasma membrane.
Correct answer: Permease- A. Membrane proteins
- B. Membrane carbohydrates
- C. Membrane glycolipids
- D. Membrane cholesterol
Explanation: Membrane proteins regulate the selective permeability of the plasma membrane, allowing the movement of molecules according to the needs of…
Correct answer: Membrane proteins
