Protozoans such as an amoeba lack a supporting cell wall and instead have a contractile vacuole that pumps out excess water that enters the cell by osmosis. This vacuole is not needed in organisms with more than one cell.

Does water move into or out of the protozoa?

Water typically moves into protozoa by osmosis, as they are usually in a hypotonic environment. This helps maintain their internal water balance and prevents dehydration.


What are osmotic stabilizers?

Osmotic stabilizers are substances that help maintain the osmotic balance in cells by regulating the movement of water and ions in and out of the cell. They prevent excessive swelling or shrinking of cells due to changes in osmotic pressure, helping to maintain cellular integrity and function. Examples of osmotic stabilizers include sugars like glucose and sorbitol.


Marine protoza do not have contractile vacule?

That's correct, marine protozoa do not have contractile vacuoles. Contractile vacuoles are typically found in freshwater protozoa and serve to regulate water balance by expelling excess water from the cell. Marine protozoa have adaptations to maintain water balance in a high-salt environment without the need for contractile vacuoles.


Which plasma constituent is the main contributor to osmotic pressure?

Albumin is the main constituent in plasma that contributes to osmotic pressure. It helps maintain the balance of fluids between the blood and tissues by exerting osmotic pressure to keep fluid within the blood vessels.


Which vacuole in the amoeba above is responsible for regulating water balance?

The contractile vacuole in an amoeba is responsible for regulating water balance by pumping out excess water to maintain osmotic balance within the cell.

How do plasma proteins in blood capillaries help to maintain osmotic balance in the body?

Plasma proteins in blood capillaries help maintain osmotic balance in the body by attracting water molecules, which prevents excessive fluid from leaving the blood vessels and helps to maintain proper fluid balance between the blood and surrounding tissues.

What functions to maintain osmotic and pH balance in the blood?

The kidneys help maintain osmotic balance by regulating the amount of water reabsorbed or excreted in the urine. They also help maintain pH balance through the excretion of hydrogen ions and bicarbonate ions in response to changes in blood pH. The lungs and buffer systems in the blood also play a role in regulating pH balance.


What do plasma proteins that remain in the blood capillaries help?

Maintain the osmotic pressure of the blood

How do fish in salt water maintain osmotic homeostasis?

Fish in salt water maintain osmotic homeostasis by drinking large amounts of water and excreting excess salt through their gills and kidneys. They also have specialized cells in their gills that actively transport salt out of their bodies to maintain the proper balance of salt and water.

What is the tonicity of a parasite?

Parasites do not have tonicity themselves, as tonicity refers to the osmotic pressure of a solution. However, parasites can be affected by the tonicity of their external environment. Parasites may have adaptations to survive in different tonicity environments to maintain their osmotic balance.
