Question 2

movement of selected flagellate genera

Answer 2

flagella

reproduction of selected flagellate genera

Answer 3

asexually, binary fission

divide longitudinally

Question 4

choanoflagellates on the protist/multicellular animal borderline

Answer 5

Only group with a collar
 All have a single flagellum
 Attach to surface by means of a stalk
 Increased size of flow field
 Most closely related to animals 
 Similar cell - common ancestor of all animals
