Question 1

Protozoa

Answer 1

single celled, non-photosynthetic, free-living organisms
no cell wall, covered by pellicle
life cycle: polymorphic

Question 2

pellicle

Answer 2

flexible protein strips
maintains cell shape and provides strength

Question 3

Life cycle

Answer 3

cyst- infective form, resistent to heat, acid, and drying
trophozoite- active form when ingested, actively grows and reproduces

Question 4

pleomorphic

Answer 4

more than one trophozoite form

Question 5

Amoebozoa

Answer 5

moves using pseudopodia (false feet)
reproduce by binary fission and feed by engulfing their prey with their pseudopodia

Answer 7

also related to amoebozoa

Question 8

Alveolata

Answer 8

alveoli, extrusomes, and microtubule framework

Question 9

Alveolata- ciliophora

Answer 9

move using cilia (eyelashes)
free-living, reproduce asexually by longitudinal binary fission, two nuclei

Question 10
