Study Notes
Sporopollenin
- Functions to prevent dehydration of zygotes
- Aids in spore dispersal
Challenges for Land Plants
- Finding water sources
- Transfer of sperm
- Resisting dehydration
- Lack of structural support
Adaptations to Land
- Rings of cellulose-synthesizing complexes
- Cuticle layer to prevent water loss
- Tracheids for water transport
- Reduced gametophyte generation
- Multicellular, dependent embryos
Apical Meristem
- Mitotic activity increases mineral absorption in roots
Algae vs. Plants
- Algae benefitted from abundant water, less solar damage, and plentiful dissolved carbon dioxide
Closest Relatives of Land Plants
- Charophytes
Adapting to Land
- The development of sporopollenin to prevent zygote desiccation
Plant Generations
- The diploid generation is the sporophyte
- The sporophyte produces haploid spores
- The sporophyte is typically larger than the haploid generation
Life Cycles
- The sporophyte may be dependent on the gametophyte
- Plant life cycles evolved so the sporophyte stage is more prominent than the gametophyte
- Meiosis produces haploid spores, not gametes
Fungi Evolution
- Early fungal fossils date back to the first land plants
- Fungi and plants both lost flagellated cells during evolution
- Both colonised land in a similar fashion
Hyphate Fungi
- Exhibit rapid growth to new food sources
