Diatoms have a cell wall made of silicon dioxide =
glass houses. Diatoms
produce oil but other photosynthetic algae 
make starch. In streams, diatoms cover rocks
that makes them slippery. Diatoms serve as a primary food source for zooplankton and is a
major oxygen producer.

sargassum

Chlamydomonas, over 150 species, are
single-celled green algae with two flagella that is found in ponds, the soil and ditches.

Euglena are elongated cells that exhibit a nucleus, chloroplasts, a contractile vacuole, flagella, and an
eyespot.

plasmodium

Fucus is a kelp (also called rockweed). Fucus is found along rocky seacoasts and salt marshes. This algae is a source of alginates, a product similar to agar.

vorticella

Volvox is a Chlorophyte that lives as a spherical colony. Each alga within the colony has two flagella and are connected to each other by thin strands of cytoplasm. The colony  moves as one. The colonies have spheres inside called 'daughter' colonies involved in  asexual reproduction.

trympanosoma

The red color
is due to pigments
which 
mask the other pigments present. 

pseudopods

non-motile

there are over 400 species of Spirogyra,
a freshwater green algae that is found in ponds, ditches and
the edge of lakes.
