Ukaryotic Radiation

Archaeplastids taxa

Red algae, green algae

land plants (monophyletic group)

Archaeplastids characteristics

chloroplast (endosymbiosis)

do most of the primary production on the planet and represent the vast majority of biomass

Metamonads

single celled amoeba-like organisms

live in water

swim using flagella that are clustered in groups of 4 and interact physically w nucleus

one lineage: Giardia (parasite)

also the termite one

Amoebozans

Monophyletic group

single celled

NO FLAGELLA… INSTEAD they move using AMOEBOID movement

• crawling process caused by cytoskeleton extension

they can also parasitize humans, and same crawling movement is used in some human immune cells

Opisthoknots

Fungi and animals (form monophyletic group).. distinguish by sperm and other MOTILE cells that swim

SINGLE POSTERIOR flagella

fungi- monophy group, absorb nutrients from dead and live organisms

animals- monophy group, they share muscle and nerve cells

SAR

Supergroup, 3 sub-lineages

• Stramenopiles - diverse, w unusual hair-like structures associated with their flagella

  • kelps, brown algae, single-celled diatoms (photosynthesizers)

  • oomycetes- parasite for crops/plants

• Alveolates - unicellular, unique flatted alveolar sacs (stiffen their cell membrane)

  • dinoflagellates - live in coral cells, give coral their color and nutrients

• Rhizaria - diverse group, live everywhere basically

  • no synapomorphy found yet

protist

eukaryote that’s NOT fungi, land plant, or animal
