Summary Introduction

To Review:

The difference between the diffusion, osmosis, plasmolysis, active transport, and imbibition.

Introduction:

The movement of the substance in the atmosphere and cells takes place through the various process. The diffusion, osmosis, plasmolysis, active transport, and imbibition are the types of movement through which substances enter in the cell.

Explanation of Solution

The diffusion can be defined as the movement of the particles, especially liquids or gases from an area of high concentration to an area of low concentration, along with the gradient.

The osmosis can be defined as the movement of the water from an area of high water concentration (hypotonic solution) to an area of low concentration of water (hypertonic solution).

Plasmolysis or the cytolysis is the movement of the water from the cytoplasm to the intercellular space or out of cells in plants and shrinking of the cytoplasm leaving the rigid cell wall.

Active transport is the movement of the substances from an area of low concentration, against the gradient. It involves the energy to transport substances.

Imbibition is the process, in which the solid or the colloidal particles adsorb the water molecule, but they do not form any solution with the water.

Conclusion

The diffusion is the movement of any particle along the gradient.

Osmosis is the movement of water against the solute gradient and according to the water gradient.

Plasmolysis is the movement of water from the cytoplasm of plant cells.

Active transport is the movement of the substance against the gradient by utilizing energy.

Imbibition is the adsorption of water without forming a solution.
