Both land plants and land animals have tube-shaped vascular tissue to transport materials throughout their bodies.

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 suggests an evolutionary link, as chloroplasts are believed to have evolved from endosymbiotic cyanobacteria, which played a crucial role in the development of photosynthetic capabilities in land plants.
