Answer to Problem 5A

Correct answer :

The correct answer is option (B) composition of cell walls.

Explanation of Solution

Explanation/justification for the correct answer :

Option (B) composition of cell walls. The fungi and plants both are eukaryotes but the cell wall composition is different, plants have cell wall composed of cellulose while fungi have cell wall that are composed of chitin. So, the correct answer is option (B).

Explanation for incorrect answer :

Option (A) composition of cytoplasm. As both plants and fungi are eukaryotic in nature there is no such difference in the composition of cytoplasm. So, this is an incorrect option.

Option (C) exoskeleton. The exoskeleton is absent in plants and present in fungi due to the cell wall composition. So, this is an incorrect answer.

Option (D) cellulose. Cellulose is cell wall composition of plants not found in fungi, the cell wall of fungi is composed of chitin. So, this is an incorrect answer.
