WebNov 9, 2024 · How do protists move? Most protists move with the help of flagella, pseudopods, or cilia. Some protists, like the one-celled amoeba and paramecium, feed on other organisms. Others, such as the one-celled euglena or the many-celled algae, make their food by photosynthesis. Does protists contain genetic material? WebImmediately the plasmasol flows through the center of the body towards the advancing end. Movement takes place when plasmasol flows. The plasmasol then gets converted to plasmagel by losing water.

WebSome protists can move toward or away from a stimulus, a movement referred to as taxis. For example, movement toward light, termed phototaxis, is accomplished by coupling their locomotion strategy with a light-sensing organ. Figure 23.8 Locomotor organelles in protists.

When conditions become unfavorable, whether due to lack of food or lack of moisture, they form spores. They can be found in damp substrates with ample bacteria and are most frequently found on decaying logs and forest duff.
