A filamentous alga, three cells of the colonial diatom Melosira, and a Cyanobacterial filament on the left. Cells and chloroplasts are clearly visible inside the cell walls of the alga. Photomicrograph taken with a Coolpix 885 at 3x zoom, using an Olympus microscope equipped with Hoffman Modulation Contrast optics, oil immersion at 1,000x magnification.
Many times a day an army of men worked hard on the sun to clean up the beach where loads of algae were left on the sand.
algae (ăl`jē) [plural of Lat. alga=seaweed], a large and diverse group of primarily aquatic plantlike organisms. These organisms were previously classified as a primitive subkingdom of the plant kingdom, the thallophytes (plants that lack true roots, stems, leaves, and flowers). More recently, most algae have been classified in the kingdom Protista or in another major group called the eukarya (or eukaryotes), which includes animals and higher plants. The algae have chlorophyll and can manufacture their own food through the process of photosynthesis. They are distributed worldwide in the sea, in freshwater, and in moist situations on land. Nearly all seaweeds are marine algae. Algae that thrive in polluted water, some of which are toxic, can overmultiply, resulting in an algal bloom and seriously unbalancing their ecosystem.
Algae from pond water. Photo taken with Zeiss PMII scope 16x plan objective and Canon EOS 60D camera equipped with Zeiss 47 60 10 intermediate tube and Leitz 4x projection lens. Modified brighfield. May be Closterium
Several species of red algae found at the base of a kelp holdfast

these are the crustose holdfasts that attach the branching coralline algae seen in the next picture to the rock.
If you look at the image in the largest size you can see branching algae starting to form on top of the crustose type algae
Algae Closterium from pond water. Nikon S-Kt pol. Moticam 2300 camera, 20x Nikon plan objective. Modified brighfield setup.
this is a tweaked picture of the algae blooms, but they did actually look this bright and green in the sunlight. the camera captured them less vividly than they actually looked.
