Osmosis is the movement of water or other solvent through a plasma membrane from a region of low solute concentration to a region of high solute concentration, tending to equalise the concentrations of the solutes. Osmosis is passive transport, meaning it does not require energy to be applied...
everyday life are:- when you keep raisin in water and the raisin gets puffed. Movement of salt-water in animal cell across our cell membrane. Plants take water and mineral from roots with the help of Osmosis. If you are there in a bath tub or in water for long your finger gets pruned.
Osmosis, the spontaneous passage or diffusion of water or other solvents through a semipermeable membrane (one that blocks the passage of dissolved substances—i.e., solutes).
1.Crucial In Plant’s Survival
Osmosis in plants
When we water plants, we usually water the stem end and soil in which they are growing. Hence, the roots of the plants absorb water and from the roots water travel to different parts of plants; be it leaves, fruits or flowers. Every root acts as a semipermeable barrier, which allows water molecules to transfer from high concentration (soil) to low concentration (roots). Roots have hair, which increases surface area and hence the water intake by the plants.
2. Helps in Regulating Our Cell’s Life
Osmosis in cell
We drink water, but also our cells absorb it by osmosis in the same way that plant roots do. As the concentration of waste products in a cell rises, the osmotic pressure between the inside and outside of the cell wall, which is a semipermeable membrane, increases, and the cell absorbs water from the blood, which is a more dilute solution that of the cell’s cytoplasm. Even the primary nutrients and minerals get transferred through osmosis into the cells. Also, our intestine absorbs nutrients and minerals through osmosis.
3. Ever tried soaking resins or dry fruits in water. what happened?
soaked-and-dry-raisins
well, when we soak resins in water they swell up and this is all that happens due to osmosis. Water travels from high concentration to low concentration and keeps moving by osmosis until the equilibrium is reached, that is when the concentration of both solutions is the same.
