What is osmosis and facilitated diffusion?

Answer 1

Diffusion is the net movement of particles(atoms,ions or molecules) from a region where are of higher concentration to a region where they are of lower concentration, down a concentration gradient.

Factors that affect the rate of diffusion

1.Temperature

2.the concentration gradient

3.Physical movement

4 surface area to volume ratio

The passage of water from the less concentrated solution to the more concentrated solution across a partially permeable membrane is a process called osmosis

Answer 2

Diffusion is the movement of molecules from the area of higher concentration to the area of lower concentration i.e.along concentration gradient .

Osmosis is the movement of water across a semi-permeable member from a solution of lesser solute concentration to a solution of higher solute concentration .

Answer 3

Diffusion is the movement of atoms and molecules from a region of higher concentration to a region of lower concentration.An example of diffusion is;A drop of ink diffuses into the glass soon,the entire glass will be coloured . Osmosis is the net movement of water molecules through partially permeable membrane,from a place of higher water concentration to a place of lower water concentration.An example of osmosis is;water enters or leaves the plants through partially permeable membranes by osmosis.These two processes are known as passive transport processes.The difference between osmosis and diffusion is that,In diffusion,we do or do not need partially permeable membrane,while in osmosis,we always need partially permeable membrane.

Answer 4

Osmosis is the movement of water molecules from an area of high water concentration to an area of low water concentration through a selectively permeable membrane. Facilitated diffusion is the process by which molecules, such as glucose or ions, move across a cell membrane with the help of specific proteins, without requiring energy input.

Answer 5

osmosis is the movement of water through a semi-permeable membrane.

if you know what facilitated means then add what diffusion means
