3 Domains of Life

Eukaryotes and have membrane-bound organelles with complex structures.

Prokaryotes: Oldest domain, an ancient type of bacteria.No nucleus-not complex-similar to eukarya

Prokaryotes: Any and all bacteria that are not Archaea BacteriaSingle celled-No nucleus-asexual reproduction

Prokaryotes: Simple organisms with no nucleus. No membrane-bound organelles.Morphology: Coccus: (Round) ~StaphylococcusBacillus: (Rod) ~ Hay BacillusSpirillum: (Spiral) ~Campylobacter jejuni

Archaea with the ability to survive some of the most extreme environments in the world (Extreme cold, hot, dry, acidic). Prokaryotic.Crenarchaeota

Heterotrophic or autotrophicMostly unicellular.All are aquatic.Motile by flagella, pseudopods, or cilia.NOT animals, plants, or fungi.

Heterotrophic. Hunt other micro-organisms for nutrition.

Autotrophic. Can internally nourish themselves by photosynthesis.

Saprophytic Heterotrophs:Digest the food externally and absorb the nutrients.

ChemoheterotrophicCell walls composed of chitinBoth sexual and asexual reproduction

(Yeast)Asexual reproductionReproduce through budding

(Bread Mould) Gametangial fusion developing into a zygospore

MushroomsReproduction takes place in the "fruiting body"

(Disease-causing)Asexually reproduction only has been observed.Produce asexual spores through sporogenesis

PhotosyntheticSexual fusion reproductionDevelop from embryos

Live in moist habitats to retain moisture out of waterLack vascular tissue

P. Bryophyta

P. Hepaticophyta

P. Anthocerophyta

FernsLeaves called frondsVascular tissue and roots for land survivability

P. Lycophyta

P. PterophytaPteridium aquilinum

Naked seedsConifer plants adaptation: Needle leaves reduce S.A., conserving water.

P. ConiferophytaScots pine

P. CycadophytaCycus revoluta

P. GnetophytaGnetum gnemon

P. GinkophytaGinkgo biloba

Flowering plantsAttract other animals to help spread seeds on land and fertilize.

P. AnthophytaMagnolia grandiflora

Embryonic development stage: Blastula HeterotrophicMotile (Mostly)
