Question

Given below are two statements:
Statement I: In a dicotyledonous leaf, the adaxial epidermis generally bears more stomata than the abaxial epidermis.
Statement II: In a dicotyledonous leaf, the adaxially placed palisade parenchyma is made up of elongated cells, which are arranged vertically and parallel to each other.
In the light of the above statements, choose the correct answer from the options given below:

• A. Statement I is true but Statement II is false
• B. Statement I is false but Statement II is true
• C. Both Statement I and Statement II are true
• D. Both Statement I and Statement II are false

Answer 1

Answer: (B)

Statement I is false but Statement II is true

Answer 2

Statement I is false. In most dicotyledonous leaves, the abaxial epidermis (lower surface) has more stomata than the adaxial epidermis (upper surface). This is an adaptation to reduce water loss.
Statement II is true. Palisade parenchyma cells are elongated, vertically arranged, and parallel to each other, maximizing light absorption for photosynthesis.
