Question

What do fungi and arthropods have in common?

a.both groups are commonly coenocytic.
b.the haploid state is dominant in both groups.
c.both groups are predominantly saprobic in nutrition.
d.the protective coats of both groups are made of chitin.
e.both groups have cell walls?

Answer 1

Fungi and arthropods both share the characteristic of having chitin in their protective layers; fungi in their cell walls, and arthropods in their exoskeletons.

Step-by-step explanation:

The commonality between fungi and arthropods is chitin in their protective layers. While both fungi and arthropods are diverse groups with characteristics unique to each, they share the trait of having structures composed of chitin. Fungi have chitin in their cell walls, which provides rigidity and structural support. This is analogous to arthropods, which have an exoskeleton also made of chitin, a tough carbohydrate that lends them their characteristic rigidity and protection.

Therefore, the correct answer to the question is 'd. the protective coats of both groups are made of chitin.' This is a distinctive feature they share, compared to other characteristics where they differ, such as their predominant nutrition form or the dominance of the haploid state in their life cycles.

Answer 2

The correct answer is d: 'the protective coats of both groups are made of chitin'
Chitin is a long-chain polymer derivative of glucose, with a structural function in various groups of animals and plants, such as of cell walls of fungi, exoskeletons of arthropods and the scales of fish. It can be compared in function to keratin found in our hair and nails.
