Stramenopiles

A diverse group of eukaryotic organisms, including diatoms and brown algae, characterized by fine, hair-like structures on their flagella.

Having two flagella, which are long, slender projections that provide locomotion to various cells and single-celled organisms.

Nanoplankton

Extremely minute (<10 μm in length) algae that are major producers in the ocean because of their great abundance; part of phytoplankton.
