NEET BIOLOGY

Detailed explanation-1: -Typically, flagellates move through an aqueous medium by the undulatory motions of the flagella. The waves of movement are generated at the base of the flagellum.

Detailed explanation-2: -Protist Movement Through Projections Cilia are thin, hair-like projections that extend outward from the cell membrane of the single-celled bodies of ciliate protists. These hair-like cilia move back and forth and in doing so, propel the organism forward or backward to enable them to move.

Detailed explanation-3: -Protists use cilia, pseudopods, or flagella to move.

Detailed explanation-4: -Rhizopods. Pseudopodia is a characteristic of a group of protozoan organisms called rhizopods under the kingdom Protista. They are characterized as eukaryotic cells that rely on pseudopod for mobility. They also use their pseudopod to engulf food particles inside a vacuole.

Detailed explanation-5: -Flagella propel the cell by spinning around their axis in a corkscrew motion. They move in response to a chemical concentration gradient, indicating a sensory feedback regulation system. This is the basis for bacterial chemotaxis.
