Caption:

Light micrograph of Spirogyra sp., a filamentous green alga (Chlorophyte, Chlorophyta). Spirogyra has characteristic spiral chloroplasts (green bands) within elongated cells of a filament. The chloroplasts contain green chlorophyll pigments and are the site of photosynthesis - the process that makes carbohydrates from carbon dioxide and water using sunlight. Spirogyra secretes a mucilaginous substance that binds adjacent filaments. Because of its slimy threads it is called, water silk or mermaid's tresses. It occurs in stagnant or slow moving fresh water.
