Question

What are the three categories into which cell locomotion can be divided?

1) Pseudopodia, flagella, and cilia
2) Endocytosis, exocytosis, and pinocytosis
3) Active transport, passive transport, and facilitated diffusion
4) Mitosis, meiosis, and cytokinesis

Answer 1

Cell locomotion can be divided into three categories: pseudopodia, flagella, and cilia. Option 1 is correct..

Step-by-step explanation:

Cell locomotion can be divided into three categories: pseudopodia, flagella, and cilia.

Pseudopodia are temporary extensions of the cytoplasmic membrane that are used by some protists, such as amoebas, to move by flowing cytoplasm into the extension. Flagella and cilia are whip-like appendages that protists like Euglena and Paramecium use for propulsion.

Lastly, cilia are hair-like appendages that often cover the cell's surface and are used by organisms like the Paramecium for propulsion. It is important to note that these mechanisms of locomotion are distinct from other cellular processes such as endocytosis, exocytosis, and different forms of transport like active transport and facilitated diffusion. Moreover, cellular division processes like mitosis, meiosis, and cytokinesis are also different and not related to locomotion.
