Stagnant Water

Again my mind has been working overtime this time to do with why when you see water that has been sitting around for awhile has a skin on it

First i had to find out what the skin was and well its just simple old Algae.

In general algae can be referred to as plant-like organisms that are usually photosynthetic and aquatic, do not have true roots, stems, leaves, vascular tissue and have simple reproductive structures.
They are distributed worldwide in the sea, in freshwater and in moist situations on land. Most are microscopic, but some are quite large.
For Algae to grow it needs a mixture of temperature, humidity, sunlight, and nutrients (food).

Algae of course isint dangerous it just looks and can small bad.

While searching i found that there are 8 different types of Algae

  • Diatoms: unicellular organisms of the kingdom protista, characterized by a silica shell of often intricate and beautiful sculpturing
  • Chlorophyta: division of the kingdom of protista consisting of the photosyntetic organism commonly known as green algae.
  • Euglenophyta: small phylum of the kingdom protista, consisting of mostly unicellular aguatic algae.
  • Dinoflagellata: large group of flagellate protistis. Some species are heterotrophic, but many are photosynthetic organisms containing chlorophyll.
  • Chrysophyta: large group of eukariotyes algae commonly called golden algae, found mostly in freshwater.
  • Phaeophyta: phylum of the kingdom protista consisting of those organisms commonly called brown algae.
  • Rhodophyta: phylum of the kingdom protista consisting of the photosynthetic organisms commonly known as red algae.
  • Cyanobacteria: phylum of prokaryotic aguatic bacteria that obtain their energy through photosynthesis. They are often referred to as blue-green algae
So now you know what that skin or slime whenever you see stagnant water, another thing i dont have to wonder about anymore.

Link to the page i got some of this information from.
