What type of protists move using extensions of their cytoplasm?

• A. Ciliates
• B. Sarcodines
• C. Flagellates
• D. Slime molds

Answer: (B)

Sarcodines are a type of protist that move by extending their cytoplasm, a mechanism known as amoeboid movement. This involves the formation of temporary projections called pseudopodia, which allow them to crawl along surfaces and engulf food particles through a process known as phagocytosis. This method of locomotion is characteristic of sarcodines, making them distinct among different groups of protists. Other groups, such as ciliates, use hair-like structures called cilia for movement, while flagellates utilize whip-like structures known as flagella. Slime molds, while they can exhibit movement and flow, do not possess the same cytoplasmic extensions used for movement as sarcodines do. The unique ability of sarcodines to move and capture prey using pseudopodia highlights their adaptability to various environments.
