Let's get to know the paramecium!

Paramecia are pond dwelling microscopic organisms. They come from the kingdom of Protista. They are most commonly found in ponds and scum, but recently some new species have been found in oceans. They are relatively large protists so they can easily be seen by a medium power microscope.

Basic Characteristics

  • Unicellular organisms, meaning that they are made up of just one cell.
  • Eukaryotic which means that they are made up of complex cells.
  • Heterotroph which means that they must eat other organisms to survive.
  • They have many different species that are difficult to tell apart because of their small size. Some of the species are Aurelia, Bursaria, Calinski, and Caudatum.

Are peramecia helpful or harmful?

Peramecia are helpful to humans, plants, and animals. The reason they are helpful is because they are heterotrophs and they feed on bacteria. These bacteria could cause sickness, so if the paramecia are consuming them it's actually an advantage for our environment. Peramecia are free living, non pathogenic organisms, meaning that they do not cause any disease so they are not harmful to humans, plants, or animals.

Why are paramecia important?

Paramecia are important to me, my community, and science because they help us by eating bacteria which can cause community illnesses including epidemics. They are also important to me, my community, and science because they could be mistaken as harmful. That is why it is important to research them to prove that they contribute to the environment in a positive way. Their scientific study can lead us to devise ways to benefit from them and we can use them to test new treatments.
