Question
All algae that do not belong to the Cyanophyta are:
a) Unicellular
b) Eukaryotic
c) Symbionts
d) Monophyletic
Solution
The correct answer is b) Eukaryotic. Algae, excluding Cyanophyta (blue-green algae which are prokaryotic), are eukaryotic organisms. This means they have cells with a nucleus enclosed within membranes.
a) Unicellular - This is not correct because not all algae are unicellular. Some, like seaweeds, are multicellular.
c) Symbionts - This is not correct because although some algae live in symbiosis with other organisms (like lichens or corals), not all of them do.
d) Monophyletic - This is not correct because algae are a polyphyletic group, meaning they do not share a common ancestor.
