Prokaryotic, Eukaryotic, Plant and Animal Cells MCQs

Q1. Which is found only in plant cells?

• A.chloroplast and cell wall
• B.nucleus
• C.ribosome
• D.mitochondria

Answer: A. chloroplast and cell wall

Textbook fact: Chloroplast and cell wall are plant-specific. Mapping the concept onto the options: Correct. The other choices: option B) 'nucleus' is wrong because In both; option C) 'ribosome' misses the point - In both; option D) 'mitochondria' fails since In both. Thus the correct option is A) chloroplast and cell wall.

Q2. Which cell/organism is described: 'prokaryotic - no membrane-bound nucleus'?

• A.bacterial cell
• B.plant cell
• C.animal cell
• D.cyanobacterium

Answer: A. bacterial cell

Asked for the unknown; data is laid out in the stem. By hence the result = bacterial cell. write the electron configuration 2, 8, 8. Hence option A) bacterial cell. Others fail: option B) 'plant cell' fails since plant cell: has a cellulose cell wall and plastids; option C) 'animal cell' misses the point - animal cell: no cell wall; small or no vacuole.

Q3. Which cell/organism is described: 'unicellular eukaryote with a true nucleus'?

• A.Amoeba
• B.animal cell
• C.cyanobacterium
• D.Paramecium

Answer: A. Amoeba

Asked for the unknown; data is laid out in the stem. By hence the result = Amoeba. write the electron configuration 2, 8, 8. Putting it together option A) Amoeba. Others fail: option B) 'animal cell' misses the point - animal cell: no cell wall; small or no vacuole; option C) 'cyanobacterium' fails since cyanobacterium: prokaryote that can photosynthesise.
