Protists

Question 1

Eukaryotes SDTs

Answer 1

• nucleus
• membrane-bound organelles
• well-developed cytoskeleton: network of fibers within cell

Question 2

endosymbiosis

Answer 2

relationship between 2 species in which one lives inside the other

Question 3

serial endosymbiosis

Answer 3

series of multiple endosymbiotic events

Question 4

primary endosymbiosis

Answer 4

phagocytosis of a prokaryote by a larger cell

• anaerobic Archaean engulfs an aerobic alpha protetobacterium (ALL EUKARYOTES, which have mitchondria)
• heterotrophic eukaryote engulfs an autotrophic cyanobacterium (photosynthetic EUKARYOTES, which have mitochondria and chloroplasts)

Question 5

secondary endosymbiosis

Answer 5

phagocytosis of a eukaryote by a larger cell

-heterotrophic Eukaryote engulfs a smaller, photosynthetic eukaryotes, which have secondary plastids

Question 6

protists

Answer 6

• mostly unicellular
• some colonial or multicellular
• complex cellular organization
