why is paramecium is in the shape of slipper
Answers
Explanation:
Paramecia are single-celled protists that are naturally found in aquatic habitats. They are typically oblong or slipper-shaped and are covered with short hairy structures called cilia. Certain paramecia are also easily cultured in labs and serve as useful model organisms
Answer:
Paramecium are called "slipper animalcules" because of their slipper like shape. They are unicellular organisms usually less than .01 inch in length and covered with minute hairlike projections called cilia. Cilia are used in moving (locomotion) and in feeding. They also provide the "touch" sense that allows the paramecium to navigate its world. Also they are involved in some very complicated chemistry that allows the paramecium to figure out what is food and what is not, what is potentially dangerous and what is not. When moving through their world, usually water or some other fluid (like inside the digestive tract of some higher organism), they move along a spiral path along there long side. When a paramecium hits an obstacle or anything else the cilia cause the body to back away at an angle and start off in a new direction. This is the so called "avoidance reaction".
Paramecium feed mostly on bacteria, which are driven into the gullet through the oral cavity by the cilia. They also have two contractile vacuoles surrounded by the C.V. canals or radiating canals in a characteristic star shape. These structures are involved in maintaining Osmotic pressure and removal of waste. A paramecium has a large nucleus called a macronucleus, without which it cannot survive and one or two small nuclei called micronuclei, without which it cannot reproduce. Reproduction is usually asexual by transverse binary fission, occasionally sexual by conjugation.
Paramecium live in fresh water ponds throughout the world and even in some ocean waters.
