Living Euglena Gracilis Swimming Under Microscope

Euglena...

Euglena eat through photosynthesis. Also, they absorb food from their environment through the cell membrane. Their flagella helps them move and they reproduce asexually. Euglena respond to their environment by their eye spot that helps them detect light.
Amoeba under microscope IV

Amoeba...

Amoeba get their food by surrounding tiny food particles with their pseudopods. They move by changing the shape of their bodies over and over again. Also, they reproduce asexually with binary fission. They respond to their environment by turning into a cyst when conditions are bad for them.
Paramecium under the microscope

Paramecium...

Parameciums use cilia to find their food. The cilia pushes microorganisms to the oral groove, or mouth, of the paramecium. It's cilia also helps the paramecium move around. When they reproduce they can reproduce sexually or asexually, this is called conjugation. It responds to environment through avoidance behavior.
Volvox Dances

Volvox...

Volvox have chloroplasts which helps them get their food through photosynthesis. Two flagella are what help them move around. Reproduction for Volvox's is very different from other protists. They have daughter colonies within them and once the colonies get too big they burst and the daughters go everywhere. If you see a volvox through a microscope you will notice that they are always in clusters. Very rarely you can find a volvox by itself. This is how they respond to their environment.
