Why is the contractile vacuole such an important organelle in Paramecium?
The contractile vacuole removes the excess water that enters the organism through osmosis (passive transport doest not require ATP) down a concentration gradient. Because the water is more concentrated on the outside of the organism in the fresh water of its habitat the water enters the organism by osmosis. The water on the outside is hypertonic and the water on the inside of the organism is hypotonic. The contractile Vacuole acts as a pump to remove and excess water without this the cell would burst from to much excess water.
Do plants require mitochondria?
They sure do! It gets a little crowded in a plant cell with chloroplasts, central vacuoles and more than enough mitochondria to burn some of the sugar made through photosynthesis.
What is the function of cell lyosomes?
Lysosomes are organelles that contain digestive enzymes (acid hydrolases). They digest excess or worn-out organelles, food particles, and engulfed viruses or bacteria. The membrane surrounding a lysosome allows the digestive enzymes to work at the 4.5 pH they require. Lysosomes fuse with vacuoles and dispense their enzymes into the vacuoles, digesting their contents.
How does the contractil e vacuole help freshwater organisms survive?
Freshwater protozoan require contractile vacuole to regulate the amount of water in its body /cell because the liquids ,in the form of waste water etc ,present in protozoan are more concentrated than the surrounding freshwater water due to presence of different acid ,etc . As a result concentration gradient develops which facilitate the flow of freshwater from surroundings inside the body of the protozoan . If this water keeps on filling inside the body then it may lead to damage to the metabolism of the protozoan & may also lead to the death of the organism . Hence, a regulating body like contractile vacuole is needed to excrete out the extra water in the protozoan's body .
What blood vessels carry blood to heart muscle?
Capillaries deliver blood tot he muscle of the heart. In fact, it is about 1 capillary per contractile cell of the heart. These cells require a rich blood supply since they are very active cells.
