Diversity of Non-Vascular Plants
Division Bryophyta
Since they do not have true vascular tissue, water and dissolved minerals can diffuse into a moss’s rhizoids.
Do no have true leaves, they have leave like structure that can perform photosynthesis and consists of a layer of cells that is only one cell thick.
Produce rootlike multicellular rhizoids that hold them to the soil.
The most familiar bryophytes are the mosses.
Grow in damp shady areas
Water and substances move through diffusion and osmosis.
Need presence of water for reproduction.
They can survive in extreme temperatures.
Division Hepaticophyta
Some can even survive in dry areas. Like other nonvascular plants, water and nutrients are exchanged by osmosis and diffusion.
They have unicellular rhizoids.
Referred to as liverworts
Leafy liverworts have stems with flat, thin leaflike structure.
They tend to grow close to the ground and in areas where moisture is rich, such as in damp soil, near water, or on damp, decaying logs.
Thallose: has a body that resembles a fleshy, lobed structure.
They are found in a variety of habitats. From the tropics to the arctic.
They lack DNA sequences
Are the most primitive of land plants.
Division Anthocerophyta
Grow in damp shady areas
presence of one large chloroplast in each cell of the gametophyte and sporophyte.
Need presence of water for reproduction
Water and substances move through diffusion and osmosis.
spaces around cells are filled with mucilage, or slime instead of air.
are called hornworts because of their hornlike sporophytes.
Its sporophyte produces much of the food used by its sporophyte and gametophyte generations.
Sporophyte supports the gametophyte.
