Question

Question 7 2 pts What do fungi and arthropods have in common? Both groups have cell walls. The haploid state is dominant in both groups. O Both groups are commonly coenocytic. Both groups are predominantly heterotrophs that ingest their food. The protective coats of both groups are made of chitin.

Answer 1

7. The correct option is:

The protective coats of both groups are made of chitin.

The cell wall of fungi is made up of chitin which is also present in the exoskeletons of arthropods. Chitin provide strenght and protection to both the organisms.

- The correct option is:

Haustoria and arbuscules.

Haustoria is a modified stem or root that originate from the hypha of a fungus. It penetrates the tissue of a host and absorb nutrients. While an arbuscules is an unique structure that is considered as a major site of exchange of nutrients between the fungus and the host.

We can say that arbuscules are intrically branched haustoria in cortex cells.

So haustoria and arbuscules are structurally and functionally more alike.
