Question

What happens when contractile vacuoles stop working?

Answer 1

Hint: In protists and unicellular algae, the contractile vacuole is a form of vacuole. In these organisms, these vacuoles play a role in osmoregulation. It also prevents these organisms from bursting due to high internal pressure.
Organelles that store cellular products are known as vacuoles.

Complete answer:
The contractile vacuole is a complex osmoregulatory organelle that regulates intracellular water balance by collecting and releasing extra water from the cell, allowing cells to survive in hypotonic conditions.
Cells have a natural tendency to consume water, which is controlled by contractile vacuoles. They keep the cell's shape and turgor pressure by removing excess water, preventing the cell from expanding and bursting. The cell can burst if contractile vacuoles aren't present or aren't working properly.
Osmoregulation is aided by the contractile vacuole, which is a specific form of vacuole. It stores cellular products similarly to a simple vacuole. Protists and unicellular algae contain it. Freshwater environments are the most common habitat for these organisms. In the environment outside the cell, the concentration of solutes is lower. The cell's external environment becomes hypotonic as a result.
Osmosis occurs in hypotonic circumstances. Water from the external environment accumulates inside the cell in contractile vacuoles as a result of this. As a result, the cell's vacuoles prevent it from absorbing too much water and bursting owing to high internal pressure.

Note:
It has been discovered that creatures without cell walls are primarily made up of contractile vacuoles. Contractile vacuoles have been lost in multicellular creatures as a result of evolution. However, contractile vacuoles can be seen in some fungal and sponge species.
It's important not to mix up vacuole and contractile vacuoles. The storage of food or water is the function of the vacuole. The role of contractile vacuoles, also known as pulsatile vacuoles, is to maintain osmoregulation.
