Study Notes
Bryophytes Overview
- Non-vascular plants lack vascular tissue and true roots, stems, and leaves.
- Transport water and minerals through osmosis and diffusion.
Major Phyla of Bryophytes
- Mosses: Belong to Phylum Bryophyta.
- Liverworts: Represented by Phylum Hepatophyta.
- Hornworts: Part of Phylum Anthocerotophyta.
Key Structures and Adaptations
- Rhizoid: Thin, root-like structures that anchor mosses and absorb water and nutrients.
- Cuticle: Waxy covering that prevents desiccation in terrestrial environments.
Reproductive Structures
- Protanema: The first filament from a germinating spore; grows horizontally and generates buds to form new gametophytes.
- Antheridium: Male reproductive structure found in some algae and plants.
- Archegonium: Female reproductive structure in certain algae and plants.
Ecological Roles
- Pioneer Plants: First species to colonize harsh environments, well-adapted for survival.
Size and Habitat
- Bryophytes generally measure around 1-2 cm tall.
- Absorb water from surrounding air or nearby sources.
Characteristics of Bryophyte Phyla
- Phylum Bryophyta: Features a short central stem with wiry branches and root-like rhizoids; most diverse bryophytes.
- Phylum Hepatophyta: Identified by flattened, drooping leaves; some have umbrella-shaped reproductive structures; reproduce through fragmentation and sexually.
- Phylum Anthocerophyta: Characterized by slimy texture, growth in moist, shaded areas, and narrow, horn-like sporophytes; can reproduce through fragmentation.
