Question

What is diffusion and osmosis?
How does diffusion and osmosis work?

Answer 1

What is Osmosis are Diffusion

•Osmosis is the process of moving solvent particles across a semipermeable membrane from the solvent’s higher concentration to the solvent’s lower concentration. The complete process does not require energy to take place

•Diffusion is the process of moving particles from a region of higher concentration to a region of lower concentration until equilibrium is reached. Simple diffusion does not require energy; however, facilitated diffusion requires ATP

How they work

•In diffusion, particles move from an area of higher concentration to one of lower concentration until equilibrium is reached. In osmosis, a semipermeable membrane is present, so only the solvent molecules are free to move to equalize concentration.

Answer 2

Diffusion is the process by which molecules move from an area of higher concentration to an area of lower concentration. Osmosis is the diffusion of water molecules across a semipermeable membrane, such as the cell membrane. In osmosis, water molecules move from an area of higher water concentration to an area of lower water concentration.

The process of diffusion and osmosis works by having molecules move from a region of high concentration to a region of low concentration. This movement is caused by the molecules having kinetic energy, which causes them to move around randomly. As they move, the molecules spread out, causing the concentration of the molecules to decrease in the area they are moving away from and to increase in the area they are moving towards. This process can be used to explain the movement of molecules across a semi-permeable membrane, such as the cell membrane. In this case, the molecules move from the area of higher concentration (inside the cell) to the area of lower concentration (outside the cell).
