Question

What trait is shared by animals and fungi?

1) extracellular digestion
2) circulatory systems
3) multiple germ layers
4) cell walls made of chitin
5) no traits are shared between animals and fungi

Answer 1

Animals and fungi share the trait of having a component made of chitin. In animals, it's found in the exoskeletons of arthropods, whereas in fungi, it composes the cell wall. Both groups are also heterotrophic and store glycogen.

Step-by-step explanation:

The shared trait between animals and fungi that is being asked about is their cell walls containing chitin. Unlike plants that have cell walls made of cellulose, both animals and fungi contain chitin, but it is found in different structural components. In animals, chitin is present in the exoskeletons of arthropods, while in fungi, it makes up the cell wall.

Additionally, fungi and animals are both heterotrophic and store carbohydrates as glycogen. However, despite these similarities, there are several distinct differences between the two groups, such as their modes of nutrition and reproduction. While animals ingest and then digest food internally, fungi secrete enzymes to digest food externally before absorbing it.
