Both are the best similar structures between plants and fungi as these parts serves as the channels which transports all the nutrients from the soil/host to the plant/fungi.
Bio-geographic isolation is the separation of part/a whole species due to either biological or geographical reasons.
Biological could be lack of food, or a more preferable source of food somewhere else, etc. Geographical could be rivers, oceans, mountains, etc.
The name given to the original cell before it divides is called the parent cell.
Some of the evidence comes from fossils, and some comes from studies that show how similar living things are to one another. By the 1930s, scientists had also learned about genes. As a result, they could finally explain how characteristics of organisms could pass from one generation to the next and change over time
