Study Notes

Bryophytes (Non-vascular Plants)

Small and simple, lacking xylem and phloem
Have rhizoids instead of roots
Grow close to the ground in clumps or sheets
Leaves are flat and often one cell in width
Must absorb water directly from their environment
Live in moist environments due to their need for water
Gametophyte phase is predominant, sporophyte is dependent on gametophyte
Antheridia produce male gametes, archegonia produce female gametes
Water is essential for reproduction, as sperm swims to reach the egg

Characteristics of Mosses

Flat leaves, often one cell in width
Grow close to the ground in clumps or sheets
Live in moist environments
Have a waxy overcoat called a cuticle to protect from dehydration
Have flagella, a tail of sperm

Ferns (Tracheophytes)

Have vascular tissue, including xylem and phloem
Produce spores, not seeds
Grow in damp environments
Sporophyte is the dominant stage in the life cycle
Gametophytes are smaller and simpler than sporophytes
Have thick cell walls, vascular tissue, and strong roots
Have underground stems called rhizomes
Have large leaves divided into smaller leaves called fronds
Have a waxy overcoat called a cuticle to protect from dehydration
Sporangia produce tiny spores cases found in sori

Life Cycle of Ferns

Spores grow into a thin gametophyte
Sperm and egg are produced
Fertilization occurs
Diploid zygote forms, making a new sporophyte plant
Sporophyte matures, producing haploid spores in sporangia

Seed Plants

Have vascular tissue and use seeds to reproduce
A seed is a plant embryo and food reserve enclosed in a protective outer covering called a seed coat (testa)
Main parts of a seed: embryo, endosperm, and seed coat

Green Algae

Are autotrophs, mostly aquatic, and photosynthetic eukaryotes
Share characteristics with land plants, including:
- Photosynthetic pigment chlorophyll
- Cellulose cell walls
- Starch storage
- Alternation of generations
- Similar genetic material

Classification of Land Plants

Two main categories: non-vascular (bryophytes) and vascular (tracheophytes)
Bryophytes lack vascular tissue and have rhizoids instead of roots
Tracheophytes have vascular tissue, including xylem and phloem
