How do chlamydomonas obtain nutrients?

I think this is what your asking for;

1. What is Chlamydomonas?

Chlamydomonas reinhardtii is a unicellular green alga.

Chlamydomonas swims with two flagella, and has chloroplasts for photosynthesis.

Chlamydomonas has nothing to do with Chlamydia, by the way.
