The contractile vacuole of a paramecium should be active when the paramecium is in what environment?

The contractile vacuole should be active when the paramecium is in water. We learned in 6th grade science that a contractile vacuole pumps water out of the cell to prevent it from getting too much water by osmosis. Without working contractile vacuoles, the cell would get too big and might die!

Should The contractile vacuole of a paramecium be active when the paramecium is in an isotonic environment?
Sure I guess well kind of... not really
In the paramecium what pumps water out of the cell?
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.
What are some methods organisms use to get rid of excess water?
humans sweat to remove water and active transport.
How does the vacoule store water?
The main role of the central vacuole is to maintain turgor pressure against the cell wall. Proteins found in the tonoplast (aquaporins) control the flow of water into and out of the vacuole through active transport, pumping potassium (K+) ions into and out of the vacuolar interior. Due to osmosis, water will diffuse into the vacuole, placing pressure on the cell wall. If water loss leads to a significant decline in turgor pressure, the cell will plasmolyse.
Does pepsin affect pH?
Pepsin doesn't affect the pH but it is active in an acidic environment.

Is vesicular transport active or passive?
The contractile vacuole collects water, then pumps it out of the cell. It requires energy to be expended, so it is a type of active transport.
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 will happen if amoeba is put in distilled water?
since distilled water is hypotinic to the amoeba's cell sap water moves into the amoeba through osmosis diluting it's cell sap, the contractile vacuole become more active in order to eliminate excess water
Where will pain occur if a lesion is present in contractile tissue?
if the lesion is in a contractile tissue i.e muscle then active n passive movements are painful and/or restricted in opposite direction of motion.
How do guppies respond to their environment?
Good environment they are exploratory and active swimming around and generally being active. Bad environment they are the opposite.

What do materials move from in active transport?
They move from the environment into the cell.
What is the moss niche?
Moist environment for active growth and sexual reproduction
