Q:

How do paramecium obtain food?

A:

Paramecium obtain their food through the use of tiny hairs called cilia; they use the cilia to move the food into the oral groove until it reaches the mouth opening. The cilia are also used to help the paramecium move.

Paramecium live in water habitats, feeding on algae, bacteria and yeast. Food and water enter into the oral groove. The food travels through the mouth into the gullet, where it accumulates and creates a vacuole. Digestive enzymes break down the vacuole's contents, allowing the nutrients to pass into the cytoplasm. The vacuole then refills with waste and moves to the anal pore. Waste is passed through the anal pore back into the paramecium's environment.

  • Q:

    What are the characteristics of Ciliophora?

    A:

    Ciliophora is a large and diverse group, but all move via hair-like structures lining their pellicles, rigid structures protecting their outer membranes, known as cilia, and all have at least two major nuclei, along with minor nuclei used for sexual reproduction. This group is largely predatory, feeding on other single-celled organisms, although some are parasites on multicellular organisms. A few even survive solely on the nutrients from symbiotic photosynthetic bacteria.

  • Q:

    Why must food be digested?

    A:

    Digestion is the process that breaks food down into the molecules that the body needs for all of its metabolic processes. Food is the body's fuel source and the source that the body's molecules and cells use to build and repair the body, but the body cannot use the food unless it has been digested.
