When the concentration of a material is the same inside and outside?
10th grade Biology – 7-3 Cell Boundaries
| A | B |
|---|---|
| the diffusion of water through selectively permeable membrane | osmosis |
| the concentration of solutes is the same inside and outside the cell | isotonic |
| solution has a higher solute concentration than the cell | hypertonic |
| solution has a lower solute concentration than the cell | hypotonic |
Which solution has the highest concentration of solute?
Hypertonic: The solution with the higher concentration of solutes.
What solution has the highest concentration of water molecules?
hypertonic solution
Where is the highest water concentration?
Water molecules move into and out of the cell at an equal rate, so the cell’s size remains constant. than a cell. This means water concentration is higher inside the cell than outside.
Does sugar move in osmosis?
Definition of osmosis This means osmosis is a special case of diffusion: the diffusion of water. This is because the selectively permeable membrane lets water molecules pass through much more rapidly than it lets sugar molecules pass through.
What is a high concentration?
A high concentration of a substance in a solution means that there’s a lot of it relative to the volume: the Great Salt Lake has very few fish because of the high concentration of salt. To say that you have good concentration skills means that you pay attention well. Definitions of concentration.
Why is osmosis low to high?
The mechanism responsible for driving osmosis has commonly been represented in biology and chemistry texts as either the dilution of water by solute (resulting in lower concentration of water on the higher solute concentration side of the membrane and therefore a diffusion of water along a concentration gradient) or by …
Where does simple diffusion occur in the human body?
In the liver, waste material, urea, is excreted onto the blood by the process f simple diffusion. Similarly, in kidneys, removal of waste chemicals and toxins and absorption of water occurs via simple diffusion. A separate active transport also occurs in some parts of the kidneys.
Where does diffusion occur in our body?
The diffusion of chemicals and gases in and out of cells is an essential activity in human organs. Diffusion of oxygen and carbon dioxide gas occurs in the lungs. Diffusion of water, salts, and waste products occurs in the kidneys. Diffusion of calcium from food into cells occurs in the intestines.
