JENPAS UG 2025 Plant Physiology & Anatomy Questions and Solutions PDF

Check out the most expected JENPAS UG 2025 Plant Physiology and Anatomy Questions based on the difficulty and style of the exam below:

Q1: Which pigment is primarily responsible for capturing light energy during the light-dependent reactions of photosynthesis?

a) Chlorophyll a

b) Chlorophyll b

c) Carotenoids

d) Xanthophyll

Answer: a) Chlorophyll a

Step-by-Step Explanation:

Step 1: Photosynthesis has light-dependent and light-independent phases.

Step 2: Chlorophyll a is the primary pigment in photosystems I and II, directly absorbing light for electron excitation.

Step 3: Chlorophyll b and carotenoids are accessory pigments; xanthophyll is a carotenoid type. Thus, option a) is correct.

Q2: In the Calvin cycle, which enzyme catalyses CO2 fixation with RuBP?

a) Rubisco

b) PEP carboxylase

c) ATP synthase

d) Cytochrome oxidase

Answer: a) Rubisco

Step-by-Step Explanation:

Step 1: The Calvin cycle fixes CO2 into organic molecules.

Step 2: Rubisco catalyses the reaction between CO2 and RuBP to form 3-PGA.

Step 3: PEP carboxylase (C4 plants), ATP synthase (photophosphorylation), and cytochrome oxidase (respiration) are unrelated. Hence, a is correct

Q3: What is the primary function of stomata in transpiration?

a) Facilitate gas exchange and water vapour loss

b) Absorb soil minerals

c) Store carbohydrates

d) Provide structural support

Answer: a) Facilitate gas exchange and water vapour loss

Step-by-Step Explanation:

Step 1: Transpiration is water vapour loss from leaves.

Step 2: Stomata allow CO2 entry and O2 exit for photosynthesis, enabling water vapour escape.

Step 3: Options b, c, and d relate to roots, parenchyma, and collenchyma/sclerenchyma. Thus, a is correct.
