Protozoa

Exploring the world of protozoa
Paramecia and other single-celled organisms – discover, examine under a microscope, understand

A single drop of water is enough to reveal an entire world. It is teeming with tiny protozoa: paramecia, amoebae, euglena, and other single-celled organisms that demonstrate how life functions at the cellular level. They move, absorb food, react to light stimuli, divide – and are therefore the perfect models for clearly illustrating basic biological principles.

Various protozoa

Our protozoa at a glance​


At Carolina Science, teachers and researchers will find a hand-picked selection of single-cell cultures bred for schools and universities. These microorganisms open a window into cell biology: from the rapid gliding of paramecia to the flowing shape of amoebas to the light-loving euglena:

Amoebas (Amoeba proteus) illustrate cell shape, cytoplasmic streaming, and food intake.

Paramecia & Co. under the microscope

Observing paramecia under a microscope is like watching biology in motion: hundreds of fine cilia propel the tiny organisms rhythmically through the water. Microscoping paramecia is an ideal introduction to cell biology and microscopy techniques.


The amoeba also provides impressive microscope images: it constantly changes its shape and uses its pseudopodia to show how food is absorbed and digested.


The euglena, on the other hand, reacts to light – an exciting example of adaptation and energy production through photosynthesis.


These observations spark curiosity and encourage scientific thinking. Students learn to recognize, draw, and interpret biological structures. With guidance, they discover how movement, respiration, and metabolism interact in a single cell.​

Experiments & Teaching Ideas


Protozoa can be used to conduct fascinating experiments – simple, safe, and with great educational value. Biology lessons become a research laboratory where students can experience biological processes for themselves.

Exemplary teaching ideas:

  • Microscoping paramecia: observing cell structure, movement, and food intake
  • Investigating light stimuli: How does Euglena orient itself in the light field?
  • Comparison of single-celled organisms: Recognizing differences between paramecia, amoeba, and euglena
  • Observing reproduction: tracking cell division under the microscope​

Microscopy experiments like these build concentration, accuracy, and responsibility when dealing with living things. They fit perfectly into topics like cells, metabolism, ecology, or evolution – and connect theory with hands-on experience.
