How do contractile vacuoles help maintain water balance in a paramecium?
The paramecium contains a vacuole called a contractile vauole. By contracting rhythmically, this specialized vacuole pumps excess water out of the cell. the control of water content within the cell is just one example of an important process known as homeostasis. Homeostasis is the maintenance of a controlled internal environment.
How does the contractile in a paramecium help maintain homeostasis?
The contractile vacuole in a paramecium excretes excess freshwater in the organism. It does this continually because water is constantly diffusing into their cytoplasm. This occurs because freshwater paramecium live in a hypotonic environment.
How do protist maintain homeostasis?
Must live in moist environment • adjust to moisture level-contractile vacuoles pump out water, for example • Produce spores to keep from drying out under less-than-ideal conditions
Is paramecium a parasite?
is the microorganism paramecium a parasite?
When a chemical is added to a microscope slide with a live paramecium the paramecium moves away from the chemical This movement is an example of?
its an example of a response to a stimulus.
How does osmoregulation occur in unicellular organisms?
Osmoregulation in unicellular organisms is by active transport. For example in Paramecium - osmoregulation is done by organelles called contractile vacuoles. These contractile vacuoles are spherical shaped structures surrounded by a series of radiating ducts. These ducts collect water and pump it into the central area by means of contractile fibres that contract and force the water into the center. When the vacuoles are full the unicellular organism contracts forcing the water outside the cell.

What type of organisms have cells with very large vacuoles?
A contractile vacuole is a type of vacuole involved in osmoregulation. It pumps excess water out of a cell and is found prominently in freshwater protists. In a Paramecium, a common freshwater protist, the vacuole is surrounded by several canals, which absorb water by osmosis from the cytoplasm. After the canals fill with water, the water is pumped into the vacuole. When the vacuole is full, it expels the water through a pore in the cytoplasm which can be opened and closed. This pore has, in some forms of paramecium, disappeared entirely when in use, leading to the idea of a "second cell" in paramecium. Other protists, such as Amoeba, have contractile vacuoles that move to the surface of the cell when full and undergo exocytosis. The contractile vacuole basically stores the extra water, in cells (mostly ciliates) in itself, so if there's a change in environment, a drought for example, the contractile vacuole can release more water into the cell. But if there's a flood, this vacuole will suck a lot of excess water out.
What is a contractile vaculoe?
An organelle of single celled organisms tasked with excreting the water that has osmotically entered the cell. Amoebae are an example of organisms that have contractile vacuoles.

Example of a protist?
Euglena, paramecium, and amoeba
Organism which utilizes intracellular digestion?
Unicellular eukaryotes achieve intracellular digestion through the process of endocytosis, phagocytosis, and use of food vacuoles and lysosomes. A paramecium is an example of an organism that uses intracellular digestion vs. humans which utilize extracellular digestion.
What is an example of unicellular?
amoeba,paramecium,euglena and yeast e.t.c
