This photograph shows a microscopic green alga called Micrasterias. Compared to many other green algae they are relatively big and can span up to one-third of a millimeter across when fully grown, barely noticeable to the naked eye. Their cells show a remarkable symmetry. Each cell consists of two half-cells being mirror images of one another. Micrasterias reproduce by dividing its cell into two equal parts. After division, a new half is growing back to restore each part’s original and symmetric shape. By continuous division, the population can grow and conquer its environment. In this image, the upper half of the cell is less developed than the bottom half due to a recent cell division. The upper half is still growing and has not yet reached its full glory. The photograph was captured using fluorescence microscopy. The chlorophyll within the cell fluoresces in red when illuminated by ultraviolet light. The size of the Micrasterias is about 0.29 mm from top to bottom. “Divide and Conquer” This photograph shows a microscopic green alga called Micrasterias.

This photograph shows a microscopic green alga called Micrasterias. Compared to many other green algae they are relatively big and can span up to one-third of a millimeter across when fully grown, barely noticeable to the naked eye. Their cells show a remarkable symmetry. Each cell consists of two half-cells being mirror images of one another. Due to their majestic size and intricate beauty, they are sometimes referred to as the queen of algae. Micrasterias are not to be expected in polluted and nutrient-rich waters that grow thick of other single-cell algal groups. In contrast, Micrasterias have to be looked for in clear waters, preferably in those with luxurious, submerged vegetation of aquatic plants. A place suitable for a queen. The photograph was captured using fluorescence microscopy. The chlorophyll within the cell fluoresces in red when illuminated by ultraviolet light. The upper half of the cell is less developed than the bottom half due to a recent cell-division. The upper half is still growing and has not yet reached its full glory. The size of the Micrasterias is about 0.22 mm from top to bottom.

Golden algae are a large group of algae, found mostly in freshwater environments. This photograph shows the species Dinobryon Divergens and is a colony of individual cells. During colony formation, an existing cell divides and one of the two daughter cells slides to the opening of the protective shell and starts to construct a new one. With further divisions, the colony starts to grow in a tree-like form. Colonies can have as many as 50 cells, each living its own life. Each cell is propelled by two flagella pulling the entire colony through the water in order to find good light. Dinobryon Divergens is a mixotrophic organism, meaning that it is photosynthetic as well as having the ability to ingest food. When the light energy or nutrients are limited, it starts eating bacteria to survive. Research shows that a colony can eat thousands of bacteria every hour if needed, providing as much as 50% of its energy requirements. Dinobryon is a potent force in controlling bacterial numbers in freshwater lakes and ponds. The entire Dinobryon colony measures just under 0.2 mm in length.

Silicoflagellates are among the group of life forms that make up the phytoplankton. They belong to a small group of marine organisms with a (silica) glass-like skeleton. The silicoflagellates, diatoms and some sponges are the only organisms to use silica instead of calcium for their skeletons. The cell size ranges from 20 to 100 microns. They have the capability to live and grow through photosynthesis as well as engulfing organic materials such as bacterias as a source of food. Living silicoflagellates propel themselves with one long flagellum to allow it to swim toward favorable living conditions, such as light. The spines on the skeleton may function in retarding sinking, which is important to a photosynthetic organism. This silicoflagellate in this photograph was captured using Differential Interference Contrast Microscopy at very high magnification. Close to the borderline of the capability of a light microscope using visible light. The silicoflagellate in this photograph was just above 50 microns (0.05 mm) across.

Micromolluscs are shelled mollusk which is extremely small even as adults. Many are only about 2 to 3 mm and a few have shells which are as small as one millimeter. Despite their tiny size, many of the shells have an elaborate sculpture as can be seen in this photograph. Because of their small size, micromollusks often remain unnoticed. It often requires great care, patience, and persistence to find micromollusks. Working with them usually also requires special techniques and special equipment compared with that needed for most of the larger-shelled species. This shelled mollusk was found in a marine water sample collected from a fish farm in Stockholm. The photograph was captured using fluorescence microscopy and illuminated by ultraviolet light. Microalgae and cyanobacteria that grow on the surface of the shell are autofluorescing in red and orange under the ultraviolet light. The shell autofluoresce in blue. The full shell is about 2.2 mm and the visible area in this photograph is about 1.3 mm from left to right.
