Non-vascular plant

[citation needed] Mosses and leafy liverworts have structures called phyllids that resemble leaves, but only consist of single sheets of cells with no internal air spaces, no cuticle or stomata, and no xylem or phloem.

In these plants, the sporophytes grow from and are dependent on gametophytes for supply of water and mineral nutrients and photosynthate, the products of photosynthesis.

They often dominate certain biomes such as mires, bogs and lichen tundra where these plants perform primary ecosystem functions.

Additionally, in bogs mosses host microbial communities which help support the functioning of peatlands.

[4] Non-vascular plants can also play important roles in other biomes such as deserts, tundra and alpine regions.
