True or False: Parasitic helminthes are motile and lack a cell wall.

• A. True
• B. False
• C. Sometimes true
• D. Depends on the stage

Answer: (A)

The statement that parasitic helminths are motile and lack a cell wall is true. Parasitic helminths, which include worms like tapeworms, flukes, and roundworms, generally exhibit motility in certain stages of their life cycle, which allows them to navigate within their hosts and establish infections. Moreover, helminths are multicellular organisms and do not possess a rigid cell wall like that found in many bacteria and fungi. Instead, they have a flexible outer covering called a cuticle. This adaptation is important for their survival within the host's environment and aids in their ability to withstand the host's immune response. In contrast, other options do not accurately describe the characteristics of parasitic helminths. They do exhibit varying degrees of motility during their life cycles but are ultimately not characterized by a cell wall. The specific characteristics of helminths reinforce our understanding of their biology and the ways in which they interact with their hosts.
