contractile vacuole
A paramecium moves using hair-like structures called cilia. Cilia beat in a coordinated fashion to propel the paramecium through its aquatic environment. The rhythmic beating of cilia allows the paramecium to move with precision and efficiency.
Paramecium moves using hair-like structures called cilia. These cilia beat in a coordinated manner to propel the organism through its environment.
The simple answer is osmosis. Osmosis is the movement of water from a dilute solution to a more concentrated solution through a semi-permeable membrane*. Any animal in freshwater has a higher concentration of dissolved substances in its cells than the surrounding water. A Paramecium is enclosed by a semi-permeable cell membrane, which lets water in but prevents most dissolved substances leaking out. Under these conditions osmosis will occur and the cell will gain water. To prevent itself swelling up and bursting Paramecium has a contractile vacuole, a structure in the cell which fills up with water and periodically expells it back into the surroundings. * The semi-premeable membrane is also called partially permeable or selectively permeable, which all mean basically the same thing.
Paramecium bursaria primarily feeds on algae, which it ingests through a structure called the cytostome. They can also engage in mutualistic relationships with the algae by harboring them within its cells and benefiting from their photosynthetic activity.
active transport, the water is pushed out through contractile vacuoles against its natural flow. Osmosis states that water flows from a higher concentration to a lower concentration, but the paramecium has less water and water is still being pushed out.

Paramecium is single celled.
Undigested food leaves the Paramecium through a structure called the anal pore, which serves as the organism's anus. The anal pore is located at the posterior end of the Paramecium and allows undigested food particles to be expelled from the cell.

A paramecium moves with hair-like things on its body called cilia.
Cytolysis
lysis
The gullet in a paramecium serves as a specialized structure for feeding. It functions to ingest food particles, primarily bacteria, by directing them into the cell through a process called phagocytosis. Once the food particles enter the gullet, they are enclosed in food vacuoles for digestion. This allows the paramecium to efficiently obtain nutrients from its environment.
Thehairs on the paramecium are called cillia, it then is able to move in all directions
