True or False: All protozoans are motile at some stage in their life cycle.

• A. True
• B. False
• C. Not Applicable
• D. Mostly True

Answer: (A)

The statement that all protozoans are motile at some stage in their life cycle is correct. Protozoans are a diverse group of single-celled eukaryotic organisms that are often characterized by the ability to move. While some protozoans may appear non-motile in certain life stages (like cysts), the majority of them exhibit motile forms that use appendages such as flagella, cilia, or pseudopodia to traverse their environments. The motility of protozoans is crucial for various biological functions, including feeding, reproduction, and evasion of predators. This characteristic is fundamental to their classification as protozoans, and it highlights the adaptability and evolutionary success of these microorganisms in diverse habitats, such as freshwater, marine environments, and soil. While there may be exceptions or specific life stages where motility is not evident, the generalization that all protozoans are motile at some point in their lifecycle holds true. Thus, this statement is accurately reflected in the answer.
