domain eukarya
- kingdom protista
- -most diverse of the eukarya kingdoms
- -no cell walls to cell walls to silica cell walls
- -pseudopodia to cilia to flagella
- -mostly asexual
- --binary fission to budding to schizogony to intermediary meiosis
15 major phyla...we need to know 5
- 1. rhizopoda (amoebas)
- 2. euglenophyta (euglenoids)
- 3. chrysophyta (diatoms)
- 4. chlorphyta (green algae)
- 5. ciliophora (ciliates)
sexual reproduction in chlorophyta
- zygotic life cycle
- zygote is the only haploid
kingdom plantae
- cell wall of cellulose
- very diverse life cycles
- chloroplasts
- sexual and asexual reproduction
- source of most chemical energy on earth
seed plants produce seeds

embryonic sporophyte, nutritive tissue, and a protective coat
advantages of seeds
- development is further advanced than in spores
- contains abundant food supply
- protective seed coat
two groups of seed plants
- gymnosperms
- angiosperms
gymnosperms (naked seed)

ovule is on the surface of the cone scale
angiosperms (vessel seed)

ovule is within an ovary
phylum coniferophyta or pinophyta
- gymnosperm
- pines and spruces
- monoecious- separate male and female parts on the same plant wind fertilized
phylum cycadophyta
- gymnosperm
- cycads
- dioecious- separate male and female plants
phylum gingkophyta
- gymnosperm
- ginkgo
- dioecious- separate male and female plants
phylum gnetophyta
- gymnosperm
- gnetophytes
- most similar to flowering plants
phylum anthophyta or magnoliophyta (2 classes)
- angiosperm
- 2 classes: class monocotyledinae or liliopsida- monocots
- class dicotyledinae or magnoliopsida- dicots
angiosperms (flowering plants)
- ovule- becomes the seed
- ovary- becomes the fruit, usually
the plant body

meristematic tissue- zone of cell division
