It is in the shape of a slipper as you can see in the diagram above ,so it is known as slipper-animalcule. In this case, the paramecium provides a safe habitat for the algae to grow and live in its own cytoplasm, however, in return the paramecium might use this algae as a source of nutrition in case there is a scarcity of food in the surroundings. September 10, 2015, Please Rate The food passes through the cell mouth into the gullet. 10. Locomotion. Paramecium: Paramecium moves by beating the cilia. Q8.

When it reaches the end of the gullet it is pinched off and forms a food vacuole with water surrounding it.The food vacuole travels all around the cell. They are protozoans belonging to kingdom Protista. Paramecium is a genus of unicellular ciliates, commonly studied as a representative of the ciliate group. Paramecium also feeds on other microorganisms like yeasts and bacteria. The paramecium uses its cilia to sweep the food along with some water into the cell mouth after it falls into the oral groove. The alimentary canal starts at … 0 6. The MyPlate Food Guide identifies daily meal proportions for the fruit, vegetable, grains, protein, and dairy food groups; and is an easy-to-understand illustration designed to help Americans build a healthy plate at meal times.
