Euk and Protistas

Composition of Protists

plasma membrane+ cell wall or shell

How protists move

float/settle, pseudopodia(false feet), flagellum/ flagella, cilia

How protists eat

autotrophs: carbon from CO2, hetertrophs: carbon from organic molecules, mixtrophs

How protists reproduce

asexual or sexual, many can alternate depending on environment

How big are protists

microscopic unicellular

multicellular protists

most are uni but multicellular ones evolved independently multiple times among euk ( ex brown algae)

Domain and Kingdom protists are in

domain: eukarya, kingdom: protista

Whats included in prokaryote domain

bacteria and archaea

whats included in eukaryotic domain

protists, plants, fungi, animals

Origin of endomembranes

invaginations (folding) of plasma membrane

Origin or Mitochondria and chloroplasts

endosymbyosis of bacteria by eukaryotic cell

Which came first chloroplasts or mitochondrium?

mitochondria; found in bacteria, eukarya and archaea so it was engulfed first

Difference between animal and plant cells

plant cells have cell wall and flagella or cilia

monophyletic clade

a true grouping- common ancestor and all the descendant species

non-monophyletic clade

an artificial grouping-does not include all descendants of a given ancestor
