Answer to Question 1

ANS: D
An auxospore is a naked diatom cell without valves. In favorable growth conditions, the auxospore
expands to the diatom's original size. It can become dormant when conditions are unfavorable for
growth. Information can be found in the section Most Phytoplankton are Photosynthetic Autotrophs



Answer to Question 2

ANS: D
These accessory pigments allow more light frequencies to be absorbed. The yellow and brown
pigments in diatoms give them the same coloration. Information can be found in the section Most
Phytoplankton are Photosynthetic Autotrophs.
