All algae that do not belong to the cyanobacteria are:a) unicellularb) eukaryoticc) monophyletic.d) evolved from land plants

The correct answer is b) eukaryotic.

Here's why:

a) Unicellular: Not all algae are unicellular. Some, like seaweeds, are multicellular.

b) Eukaryotic: All algae, except for cyanobacteria (which are prokaryotic), are eukaryotic. This means their cells contain a nucleus and other organelles enclosed within membranes.

c) Monophyletic: Algae are not monophyletic, meaning they do not all come from a common ancestor. They are a polyphyletic group, with different types of algae having different evolutionary origins.

d) Evolved from land plants: This is not true. In fact, it's the other way around - land plants evolved from green algae.
