However for ease of communication, we often refer to this paraphyletic grade as the bryophytes. The bryophytes are the earliest diverging groups of plants and in many ways are similar to the very first land plants. Bryophytes typically grow in wet environments.

Each gamma cup gives rise to numerous gametes that are released when water droplets splash into the cup thus transported the gametes to favourable sites to grow into new plants. 2.)

A gemma (plural gemmae) is a single cell, or a mass of cells, or a modified bud of tissue, that detaches from the parent and develops into a new individual. This type of asexual reproduction is referred to as fragmentation. It is a means of asexual propagation in plants. These structures are commonly found in fungi, algae, liverworts and mosses, but also in some flowering plants such as pygmy
