osmosis!
Dry raisins swell up in water due to the process of osmosis. When raisins are placed in water, the water moves through their semi-permeable membranes into the dehydrated cells, where the concentration of solutes is higher. This influx of water rehydrates the raisins, causing them to expand and regain their plump shape. The process reflects the natural tendency of cells to balance solute concentrations on both sides of the membrane.
Yes, the raisins will swell due to osmosis, where the solvent goes from a low solute concentration to a higher solute concentration, which in this case, is from the distilled water to inside the raisin.
I know of no such process. Cells swell and burst due to being in an hypotonic environment. Water seeps into the cell due to differing inter and intra cellular osmotic gradients. Cells also carry out apoptosis
Yes, a cell can swell due to water influx, which can occur in response to changes in osmotic pressure, nutrient intake, or other cellular processes. However, excessive swelling can be harmful and lead to cell damage or lysis.
Due to lack of rigid cell wall
Boiling ruptures the cell membrane of raisins, preventing osmosis from taking place as the cell membrane is necessary for the process. In a hypertonic solution, the raisins would not absorb water due to the damaged cell membrane. In a hypotonic solution, they would not release water as the cell membrane cannot regulate the movement of water.
If you put a cell in a hypotonic environment, such as a blood cell in water, it will swell up due to osmosis and lyse.
it will swell
If a cell is placed in distilled water, it will likely absorb water and swell up due to osmosis. When transferred to a 5 percent salt solution, the cell will lose water and shrink, as the high salt concentration outside the cell will cause water to move out of the cell by osmosis. This process is known as plasmolysis.
It could lyse (break)
A condition that causes cells to swell and burst is called cytolysis. This occurs when there is an influx of water into the cell, typically due to a hypotonic environment where the solute concentration outside the cell is lower than inside. The excess water causes the cell to swell and can ultimately lead to its rupture.
The turgid condition of a cell is primarily due to the presence of water flowing into the cell through osmosis. This influx of water causes the cell to swell and become firm due to the pressure exerted by the cell wall pushing back against the expanding cell membrane.
