Molecules will move into or out of the cell until it becomes isotonic to its surroundings. This means that the concentration of the molecules inside the cell is equal to the concentration of the molecules outside the cell.
The transport vesicle is the vacuole that regulates movement of materials between the cell's organelles and the cytoplasm. It helps to transport molecules such as proteins and lipids to different parts of the cell or to the cell membrane for secretion.
In general, molecules that cannot diffuse across the cell membrane are either very large, such as starches and fats, or very polar.
I semi-permeable membrane is a membrane when only certain substances can pass through it.it is a membrane that will only allow certain molecules through it . in general oxygen , food and water are allowed to enter ; waste products are allowed to exit and harmful substances are kept out. hope this helps.
The movement of fluids in and out of a cell is called osmosis. Osmosis specifically refers to the passive movement of water molecules across a semipermeable membrane from an area of lower solute concentration to an area of higher solute concentration. Additionally, the general movement of fluids and other substances into and out of cells can also be described by terms like diffusion and active transport, depending on the mechanisms involved.
Diffusion is the movement of a mineral or nutrient moving across the concentration gradient of a membrane. The closest word to diffusion would probobly be osmosis, which is the movement of water through a membrane.
The outer boundary of a general animal cell is the cell membrane.
The transport vesicle is the vacuole that regulates movement of materials between the cell's organelles and the cytoplasm. It helps to transport molecules such as proteins and lipids to different parts of the cell or to the cell membrane for secretion.
This would depend on A) the molecule B) the membrane/proteins involved, and C) the concentrations.Diffusion in general would be the passage of molecules from an area of higher concentration to an area of lower concentration.This can be broken down into either FACILITATED DIFFUSION(through specialized integral protein channels) or SIMPLE DIFFUSION (through the membrane itself, only with tiny uncharged particles).ACTIVE TRANSPORT is normally from an area of lower to higher concentration and requires ATP expenditure.
Diffusion is the net movement of a substance through a membrane from a higher concentration to a lower concentration. Osmosis is the diffusion of water.
Osmosis specifically refers to the movement of water molecules through a semi-permeable membrane, while diffusion is a more general term that applies to the movement of any type of molecule from an area of high concentration to low concentration. Osmosis is a type of diffusion specific to water molecules.
Diffusion and osmosis are both processes by which molecules move from an area of high concentration to an area of low concentration. Osmosis specifically refers to the movement of water molecules across a selectively permeable membrane, while diffusion is a more general term that refers to the movement of any type of particle (not just water).
In general, molecules that cannot diffuse across the cell membrane are either very large, such as starches and fats, or very polar.
No osmosis is actually a special term used just for the movement of water across a cell membrane. We don't use that term for anything else. Diffusion is for the movement of other substances but not always involving a cell membrane. For example, scent can diffuse in the air. Science tends to be like this but it is important to use exact terms.
Osmosis and diffusion are similar in that there is a net movement of molecules from a high concentration of those molecules to a lower concentration. Osmosis is a special type of diffusion that deals with the movement of water only. Osmosis also deals with a semipermeable membrane (like our cell membranes). Diffusion can occur anywhere such in a glass of water when you add sugar but it can occur around cells.
Diffusion-the random movement of molecules from an area of higher concentration to an area of lower concentration.Osmosis-the diffusion of water across a semipermeable membrane.
