Non-vascular plants

Non-vascular plants, commonly known as bryophytes, are a group of simple, land-dwelling plants that lack specialized tissues for transporting water and nutrients, which limits their size and habitat to moist environments. This group includes mosses, liverworts, and hornworts, and they reproduce via spores rather than seeds.

Overview

Non-vascular plants, or bryophytes, are a unique group of plants that lack vascular tissues, which are essential for transporting water and nutrients in higher plants. They include mosses, liverworts, and hornworts, and are typically found in moist environments. Bryophytes play a vital role in ecosy...

Key Terms

Bryophyte
A non-vascular plant that includes mosses, liverworts, and hornworts.

Example: Mosses are a common type of bryophyte found in damp areas.

Thallus
The body of a bryophyte that is not differentiated into leaves, stems, or roots.

Example: The thallus of liverworts can be flat and leafy.

Rhizoid
A root-like structure that anchors bryophytes to the substrate.

Example: Mosses use rhizoids to attach to soil or rocks.

Gametophyte
The dominant stage in the life cycle of bryophytes that produces gametes.

Example: In mosses, the green leafy part is the gametophyte.

Sporophyte
The stage in the life cycle of bryophytes that produces spores.

Example: The stalk and capsule of a moss represent the sporophyte.

Spore
A reproductive cell that can develop into a new organism.

Example: Mosses release spores to reproduce and spread.
