Compare homologous and analogous structures

In the field of comparative anatomy, homologous structures can be described as structures which are present in different organisms which are similar and show that the organisms had a common ancestor in the past. On the other hand, analogous structures can be described as structures which are similar in function but might not possess a common origin.

Example of the homologous structure is the forelimb of dogs, humans and birds. All these structures might not perform the same function but are structurally similar.

Example of analogous structure includes the wings of a bat and bird. Although similar in function, they do not show a common origin.

some fungi obtain their nutrients from a living host (plant or animal) and are called most biotrophic fungi have fairly narrow host ranges—they are specialized on a limited called rhizomorphs that allow the fungus to grow from one tree to another. ascospores are formed inside a sac-like structure called an ascus. so your answer is a
