Plant Tissues MCQs

Q1. Which tissue is dead and provides rigidity?

• A.sclerenchyma
• B.parenchyma
• C.collenchyma
• D.meristem

Answer: A. sclerenchyma

NCERT fact (biology, chapter 'Tissues in Action'): Sclerenchyma is dead and rigid. Why option A fits - Correct. Distractor analysis: option B) 'parenchyma' misses the point - Living, thin-walled; option C) 'collenchyma' doesn't hold - Living, flexible. Final answer - A) sclerenchyma.

Q2. Which plant tissue is described: 'located at root/shoot tips; increases length'?

• A.Apical meristem
• B.Intercalary meristem
• C.Parenchyma
• D.Chlorenchyma

Answer: A. Apical meristem

The idea this question leans on: Identify the defining feature of the structure/tissue named in the question; match that feature against the four options => only one option is consistent with the textbook description; therefore the correct identification = Apical meristem. That fits the listed correct option directly - Correct. As for the rest: option B) 'Intercalary meristem' doesn't hold - Intercalary meristem: present at internodes/leaf bases; option C) 'Parenchyma' fails since Parenchyma: thin-walled living cells that store food. Hence the answer is A) Apical meristem.

Q3. Which plant tissue is described: 'increases girth/thickness of stem'?

• A.Lateral meristem (cambium)
• B.Parenchyma
• C.Chlorenchyma
• D.Aerenchyma

Answer: A. Lateral meristem (cambium)

NCERT fact (biology, chapter 'Tissues in Action'): Identify the defining feature of the structure/tissue named in the question; match that feature against the four options => only one option is consistent with the textbook description; therefore the correct identification = Lateral meristem (cambium). Why option A fits - Correct. Distractor analysis: option B) 'Parenchyma' is wrong because Parenchyma: thin-walled living cells that store food; option C) 'Chlorenchyma' misses the point - Chlorenchyma: parenchyma with chloroplasts; photosynthesis. Final answer - A) Lateral meristem (cambium).
