Origin and evolution of eukaryotes

Question 1

4 supergroups of eukaryotes

Answer 1

1. Excavata
2. SAR
3. Archaeplastida
4. Unikonta

Question 2

endosymbiosis

Answer 2

one organism living inside another ( host cell)

Question 3

process of symbiosis

Answer 3

1. a cell (could be archae) engulfs alpha-proteobacterum and becomes an animal like cell with nucleus and DNA
2. a cell engulfs cyanobacterum and becomes an plant like cell with chloroplast

Question 4

Secondary symbiosis

Answer 4

1. red algae is engulfed by heterotrophic eukaryote –> algae and cell –> becomes stramenopiles or alveolate
2. green algae is engulfed by heterotrophic eukaryote–> algae and cell –> euglenid with plastid or chlorarahyte
