A brief concept on diffusion and osmosis

The process of transfer of ions, molecules, particles from their higher concentration area to the lower concentration area. The factors that affect the rate of diffusion are
1. Temperature: The rate of diffusion is directly proportional to the temperature. When the temperature is raise then the rate of diffusion also raises, but when the temperature is deceases the rate of diffusion is also decreases. Hence it is one of the important factors.
2. Density: Density is another important factor responsible for the rate of diffusion. When the density is decrease the rate of diffusion is increases because there is variation to dissolve the substance so in another word we can also say that the density is inversely proportional to the rate of diffusion.
3. Concentration of the substance: The concentration of the substance indicates the strength of the substance of which it has the capability to dissolve the substance. The higher the concentration the higher is the rate of diffusion. So the concentration of the substance is directly proportional to the concentration of the substance.
4. Concentration gradient: The concentration gradient of the substance is directly proportional to the rate of diffusion. The rate of diffusion increases when the concentration gradient is increase.so they are direct to each other.
5. Surface area: The surface area is directly proportional to the surface area. As the surface area increases the more the diffusion takes place fastly. The diffusion depends on the surface area.
    The osmosis is defined as the movement of solvent or water molecules from their higher concentration area to the lower concentration area is called osmosis. Mainly there are two types of osmosis they are as follows
1. Endosmosis: It is the movement of solvent molecules into the cell from the hypotonic solution that swells the cell.
2. Ectosmosis: It is the process of loss or exist of water when cell is kept in the hypertonic  solution is called ectosmosis.
              Hence in this way the osmosis and diffusion are well explained and both this type of things plays a vital role in the plant function.
