Answer 2

Most protists are microscopic and unicellular, some live as colonies that behave in some ways as a group of free-living cells and in other ways as a multicellular organism, many protist cells are multinucleated; in some species, the nuclei are different sizes and have distinct roles in protist cell function.

Question 3

pellicles

Answer 3

an outer cell covering composed of interlocking protein strips that function like a flexible coat of armor, preventing cells from being torn or pierced without compromising their range of motion

Question 4

What protists have chloroplasts?

Answer 4

Photosynthetic protists (photoautotrophs)

Question 5

What protists consume organic material for energy and sometimes photosynthesis?

Answer 6

asexual (binary or multiple fission) and sexual reproduction

Question 7

What are cysts?

Answer 7

A protective, resting stage to wait out environmental stressors.

Answer 8

Excavata, Chromalveolata, Rhizaria, Archaeplastida, Amoebozoa, and Opisthokonta

Question 9

Answer 9

carbon fixation

Question 10

Answer 10

primary producers

Question 11
