Question

SO${}_2$ pollution affects which part of the plant?

• A. Chloroplast
• B. Mitochondria
• C. Endoplasmic reticulum
• D. Lysosome

Answer 1

Answer: (A)

Chloroplast

A. Chloroplast are the green coloured plastids that take part in photosynthesis.

B. Mitochondria are called the power house of the cell because these are associated with cellular respiration and energy generation of the cell.

C. Endoplasmic reticulum are membrane bound channels, seen in the form of a network of delicate strands and vesicles in the cytoplasm.

D. Lysosomes are single membrane bound structures which contain hydrolytic enzymes in them.

SO${}_2$ pollution inhibits photosynthesis and thus, affects chloroplasts because chloroplasts take part in photosynthesis.

So, the correct answer is 'Chloroplast'
