Question 1

Secondary endosymbiosis

Answer 1

Process in eukaryotic evolution where a heterotrophic eukaryote engulfed a photosynthetic eukaryote which formed a symbiotic relationship

Question 2

Excavata

Answer 2

Clade that was proposed based on feeding groove

Question 3

Diplomonads

Answer 3

Have mitosome (reduce mitochon) which lack ETC making them anaerobic

Question 4

Answer 8

Photosynthetic algae that have a wall with silicon dioxide embedded in its matrix

Question 9

Brown algae

Answer 9

Multicellular photosynthetic protists with brown color due to carotenoids in its plastids

Question 10

Alternation of generation

Answer 10

Life cycle where there is a multicellular diploid form & multicellular haploid form

Question 11

Heteromorphic

Answer 11

Sporophyte and gametophyte are structurally different

Question 12

Isomorphic

Answer 12

Sporophyte and gametophyte look alike but differ in chromosome number

Question 13
