Question

hello guys !!
What is osmosis ?? Write osmosis with full explanation and examples !!​

Answer 1

Answer:

“Osmosis is a process by which the molecules of a solvent pass from a solution of low concentration to a solution of high concentration through a semi-permeable membrane.”

Example:

Osmosis has a significant role to play in plants, animals and also in humans. In an animal cell, osmosis helps in absorbing water from the intestines to the blood.

Listed below are more examples of Osmosis.

• The absorption of water from the soil is due to osmosis. The plant roots have a higher concentration than the soil, therefore, the water flows into the roots.

• The guard cells of the plants are also affected by osmosis. When the plant cells are filled with water, the guard cells swell up and the stomata open.

• If a freshwater or saltwater fish is placed in the water with different salt concentrations, the fish dies due to entry or exit of water in the cells of the fish.

• Humans suffering from cholera are also affected by osmosis. The bacteria that overpopulate the intestines reverse the flow of absorption and do not allow water to be absorbed by the intestines, which results in dehydration.

• When the fingers are placed in water for a longer period of time, they become pruney due to the flow of water inside the cells.

Hope It helps....
