Classes of Algae
Algae exist in oceans, rivers, lakes, ponds and snow. Algae usually are green but can be other colors. There are seven divisions of algal cells: green, euglenoids, diatoms, fire, red, yellow-green, and brown.
Characteristics of Algae
Some types of algae form scum on water when conditions are calm. The algae can be blue-green or greenish-brown and often smell musty or grassy. Some produce toxins. The most common swimming pool algae is green. It varies from blue-green to yellow-green to dark-green. It can cling to walls or float, turning water hazy green. Algae lack true roots, stems, and leaves.
Algae Diversity and Reproduction
Algal biofuel from algae oils is a renewable alternative to fossil fuels. Algae have diverse life cycles and range from microscopic to giant 60-metre kelps. The scientific study of algae is phycology. Some references include blue-green algae, which can bloom and be toxic.
Algae Classification
The largest algae are seaweeds. Microscopic, planktonic algae are called phytoplankton. Algae include a polyphyletic group, with plastids of cyanobacteria origin acquired differently. Algae grow in marine and freshwaters, as benthic or free-floating organisms. Macroalgae comprise brown, green, and red groups, with colors from pigments besides chlorophyll. Microalgae occur in both habitats; cyanobacteria are microalgae.

Examples of Algae
What are three examples of algae? Examples of multicellular algae include giant kelp and brown algae. Unicellular examples include diatoms, Euglenophyta, and Dinoflagellates. Algae exist in oceans, rivers, lakes, ponds, and snow. Algae usually are green but can be other colors. There are seven divisions of algal cells: green, euglenoids, diatoms, fire, red, yellow-green, and brown.
