Compare algae and mosses. What complications have occurred in the structure of mosses in comparison with algae?

The differences between algae and mosses are enormous. First, in mosses, the body is already divided into sections, the functions of which cannot be performed by other parts (in algae, such a division does not exist). Due to life on land and the influence of gravity, the structure of mosses is stronger, they can stand (the stem holds the weight of the plant). Moss has root-like formations that can absorb moisture and nutrients from the soil. Also, in mosses, plants of two sexes differ both functionally and in appearance.
