The algal herbarium holds a small collection of specimens classified under Euglenophyta, Chryosphyta and Xanthophyta.
The euglenoids are unicellular green organisms with one or two flagella and a red eyespot. They often move with a characteristic squirming motion. Most species of euglenoids inhabit freshwater environments.
Chrysophyta (golden-brown algae)
The cells of the Chrysophyta are characteristically golden to yellow-brown due to the presence of accessory pigments. They mostly occur in freshwater habitats.
Xanthophyta (yellow-green algae)
The Xanthophytes are photosynthetic organisms which live mostly in freshwater. The typical yellow-green cells are due to the presence of the accessory pigment diatoxanthin in two or more chloroplasts.
