Answer 1

The piece of evidence that supports the argument that land plants evolved due to the presence of microbes is:

The chloroplasts of land plants, which allow them to carry out photosynthesis, is a structure similar to cyanobacteria.

This is because the endosymbiotic theory suggests that chloroplasts in land plants evolved from cyanobacteria, which are a type of microbe. This connection indicates that land plants may have evolved in part due to their association with such microbes.
