A light micrograph or photomicrograph is a micrograph prepared using an optical microscope, a process referred to as photomicroscopy.At a basic level, photomicroscopy may be performed simply by connecting a camera to a microscope, thereby enabling the user to take photographs at reasonably high magnification.
The Zygnemataceae are cosmopolitan, but though all generally occur in the same types of habitats, Mougeotia, Spirogyra, and Zygnema are by far the most common; in one study across North America, [3] 95% of the Zygnemataceae collected were in these three genera. Classification and identification is primarily by the morphology of the conjugation ...
Spirogyra (common names include water silk, mermaid's tresses, and blanket weed) is a genus of filamentous charophyte green algae of the order Zygnematales, named for the helical or spiral arrangement of the chloroplasts that is characteristic of the genus. Spirogyra species, of which there are more than 500, are commonly found in freshwater ...

The body plan of Zygnematophyceae is simple, and the group appears to have gone through a secondary loss of morphological complexity. [8] The most basal members are unicellular, but filamentous species have evolved at least five times, [9] and a few species form colonies. [7]
A simple microscope uses a lens or set of lenses to enlarge an object through angular magnification alone, giving the viewer an erect enlarged virtual image. [1] [2] The use of a single convex lens or groups of lenses are found in simple magnification devices such as the magnifying glass, loupes, and eyepieces for telescopes and microscopes.
Scribble (voiced by Micky Dolenz) - A dog from the United States; who is a Spy Dog-in-training. He is the comic relief of the group and is known to eat anything. Scribble appears to be a Beagle mix.

Spirograph is a geometric drawing device that produces mathematical roulette curves of the variety technically known as hypotrochoids and epitrochoids.The well-known toy version was developed by British engineer Denys Fisher and first sold in 1965.
