Give me different between the Diffusion …

There is no comparison between diffusion and tissue. So mention some points may help you to understand Diffusion and tissue.

• Diffusion is the process of movement of molecules under a concentration gradient.
• It is an important process occurring in all living beings. Diffusion helps in the movement of substances in and out of the cells.
• The molecules move from a region of higher concentration to a region of lower concentration until the concentration becomes equal throughout.
• Liquid and gases undergo diffusion as the molecules are able to move randomly.

Tissue

• A group of cells that are similar in structure and work together to do a peculiar function is called tissue.
• Tissues provide structural strength, mechanical strength, show division of labour.
• The use of tissues in multicellular organisms is to provide structural and mechanical strength as well as to allow division of labour.
