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.Learn More
Paramecium have tiny hair-like structures, called cilia, around the outer edge of their cell that move back and forth in a whip-like fashion, allowing movement in water. Paramecium normally attach to the bottom of a body of water, such as a pond, stream or puddle.Full Answer >
A paramecium is a single-celled creature that resembles a slipper and mainly lives in bodies of water such as ponds, lakes and rivers. Paramecia belong to the group of organisms called protists.Full Answer >
To access the online version of the Holt "Modern Biology" textbook, students need to obtain a key code for the book. Holt assigns a key code to schools that register for its online programs. If students do not have this code, they should ask their school's technology administrator for it.Full Answer >
The mass that is neither incorporated into the animal’s body nor passed as waste is converted directly into energy. Even though the mass of a given food item decreases when it is eaten, the Law of Conservation of Mass-Energy remains unbroken. This is how animals derive energy from their food so that they can carry out all of their biological processes.Full Answer >
