Question

In the absence of which of the following will photosynthesis not occur in leaves?

• A. Guard cells
• B. Chlorophyll
• C. Vacuole
• D. Space between cells

Answer 1

The correct option is B

Chlorophyll

The correct option is B.

Explanation of the correct option: -

1. Chlorophyll is the green pigment found in plant leaves.
2. Chlorophyll in the leaves absorbs solar energy and performs photosynthesis.

Explanation of the incorrect options: -

Option A: -

1. Another type of plant single-cell model for studying early signal transduction and stress tolerance processes in plants is guard cells.
2. Guard cells are found in the leaf epidermis, surrounded by stomatal holes.
3. CO₂ and water input and outflow from leaves are controlled by guard cells.

Option C: -

1. A vacuole is a membrane-bound cell organelle.
2. Vacuoles are tiny structures found in animal cells that assist trap waste materials. Vacuoles in plant cells aid in water balance.
3. A single vacuole can sometimes take up the majority of the plant cell's inner volume.

Option D: - Photosynthesis has no aspect on this segment of the plant cell.

Final Answer: - In absence of chlorophyll photosynthesis will not occur.
