Protists

By Maddison Rhodes

Amoeba

The amoeba is a glob shaped protist, that moves by changing its shape and pushing its cytoplasm to make false feet, or pseudopods. For the amoeba to eat it surrounds it's food with the pseudopods and engulfs the food. The amoeba goes thru asexual reproduction, or reproduction without sexual interaction, called binary fission. When there isn't much, or any, water around the amoeba it becomes a cyst, which is a small shell around the protist.

Volvox

The volvox gets its food from photosynthesis. For the volvox to move it uses two flagella to move. When the volvox reproduces the parent ball bursts because of the daughter colonies getting mature. The volvox doesn't necessarily have a way to respond to their environment, since they are constantly in daughter colonies all together.

Paramecium

The paramecium is a small protist with an oral groove, that acts like a mouth, and cilia; To move. The paramecium feeds on microorganisms and sweeps them into their oral groove. Parameciums does Asexual and Sexxual reproduction; conjugation. The paramecium can know when danger is about to occur and can avoid it; Avoidance behavior. They also can shoot trichocysts out, trichocysts are small stringy things to hurt their enemies.

Euglena

For the Euglena to absorb food it either will go through photosynthesis, or absorbs food through the membrane. For it to move it flicks its flagella. When it goes through reproduction, it does asexual; binary fission. The euglena has a small eyespot, which can help detect light.
