Color provides a major clue about the pigments the algae uses for photosynthesis:

: Sites like the NIWA Algae ID Guide and the Landcare Research Guide provide visual references for different habits.

: Often Diatoms . They contain fucoxanthin and have silica in their cell walls, making them look like tiny shards of glass under a microscope. 3. Use Quick Field Tests

: These are large and "plant-like" but lack true roots and leaves.

: If you can pick up the algae with a stick and it hangs like hair, it is likely a filamentous green alga. If it is slimy and slips off immediately, it may be cyanobacteria .
