Is fucus filamentous or colonial algea?

Question

Am a bit new to biology SE. My question is wether fucus is filamentous or collonial form of algea?Does a form of algea have to be collonial or fillamentous or it can be something else? https://en.m.wikipedia.org/wiki/Fucus_vesiculosus

Answer 1

I would suggest looking up some basic sources on types of algae. For example, that source that I link to says this:

Algae vary considerably in size, shape, and growth form.
They can be:

• Single celled
• Many celled - either colonially or as filaments of cells; or
• Elaborate plant bodies with differentiated cell types

In this case, I believe that Fucus would be in the third category ("elaborate plant bodies").

But note that these are informal categories, they don't really correspond to taxonomy or evolution or anything.
