To maximize the rate of diffusion of a substance across a membrane, you can increase the concentration gradient by maintaining high concentration levels on one side. You can also increase the surface area of the membrane for more contact between the substance and the membrane. Additionally, ensuring the membrane is thin and permeable will aid in faster diffusion.
Diffusion across a cell membrane occurs when concentrations of a substance are higher either inside or outside the cell.
Movement across a membrane that does require energy is called active transport.
The term that describes the difference in the concentrations of a substance across a cell's membrane is "concentration gradient." This gradient occurs when there is a higher concentration of a substance on one side of the membrane compared to the other, leading to potential movement of the substance from the area of higher concentration to lower concentration, often through processes like diffusion.
osmosis is a special type of diffusion that involves water moving across a cell membrane hopefuly this helped :)
Facilitated diffusion is a type of passive transport in which a substance moves across the cell membrane from high to low concentration. In this situation, the substance moves with the concentration gradient, and with the help of carrier molecules, it is able to make it's way across the membrane smoothly and without the expense of energy. Active transport, on the other hand, is the movement of a substance across the cell membrane from low to high concentration, making the transport a bit more difficult and calling for the use of energy. Transport proteins recognize the substance and allow it to cross through the membrane.

The diffusion of substances across a membrane is driven by the concentration gradient, which is the difference in concentration of a substance on either side of the membrane. Substances naturally move from areas of high concentration to areas of low concentration in order to reach equilibrium.
The term that describes the difference in concentrations of a substance across a cell's membrane is called the concentration gradient. This gradient drives the movement of substances such as ions or molecules across the membrane through processes like diffusion or active transport to achieve equilibrium.

Osmosis is specifically the movement of water molecules across a selectively permeable membrane. It is not involved in the diffusion of other substances like ions or solutes.
Osmosis and diffusion.
Facilitated diffusion
No, facilitated diffusion does not require energy for the movement of molecules across the cell membrane.
Facilitated diffusion does not require energy for the transportation of molecules across the cell membrane.
Facilitated diffusion does not require energy to transport molecules across the cell membrane.

Diffusion is what carries materials across the plasma membrane. The diffusion cannot be moved across water.
