Why is the contractile vacuole such an important organelle in Paramecium?
The contractile vacuole helps regulate osmotic pressure by pumping out excess water that enters the cell. Paramecium lives in freshwater environments where osmotic pressure fluctuations can be harmful. The contractile vacuole is critical for maintaining proper internal water balance and preventing cell bursting.
Why is that a Paramecium sp. which lives in the ocean does not possess a contractile vacuole where as a similar Paramecium sp. which lives in fresh water must have such a cytoplasm organelle?
Freshwater Paramecium must have a contractile vacuole to regulate water intake and prevent cell lysis due to the hypotonic environment. In contrast, ocean-dwelling Paramecium face an isotonic environment that does not require active regulation of water intake or expulsion, therefore they do not need a contractile vacuole.
Why do you think Plant cells have bigger vacuoles than Animal cells?
I think Plant cells have bigger vacuoles than Animal cells because, plants live off of rain, soil, oxygen, and sunlight, and all they need to do it grow. And, animals live off of real food, exercise, water, etc. Therefore, animals need a lot more things to live, and the reason why the vacuole is bigger is because it has a lot more things going through it. And, plants just sit there all day and do nothing except grow. Fun, fun. -A 13 year old chick.
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 cells need hypotonicity to be at homeostasis?
Red blood cells require a slightly hypotonic environment to maintain their normal shape and function. This is because water moves into the cell by osmosis, helping to prevent the cells from shrinking or bursting.
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.
What is the difference between require and require once?
