A
verdiplante (green plants)
2
Q
What types of chlorophyll
A
CH A,B, accessory pigments but not phycobilins
3
Q
synapomorphies of land plants
A
multicellular
-> extreme cell division
->but could be a large single-celled plant
has a sheathed egg, the archegonium with single embryo
some need vasculature to transport water and nutrence
4
Q
whats coenocytic?
A
Cell divisions where it divides many times, but never completely splits
5
Q
bryophyte characteristics
A
- > includes mosses, liverworts and horn warts
- > Oldest land plants } Lack leaves and vasculature
- > Uses air to disperse spores
- > gametophyte dominant, sporophyte not free-living
6
Q
vascular plants
A
- > ones with rooms phloem(sugars and nutrence) and xylem (water)
- > reproductive organs on shoots, roots pick up water and nurturance
- > Sporophyte dominant, gametophyte can be quite small
7
Q
vascular fertilization
A
female: Archegonium, egg in a flask like sheet
male: Antheridium, a pigmented ball
Pollen makes sperm
-> Fertilize through air
