What is the importance of diffusion in biology?

What is the importance of diffusion in biology?

Diffusion is crucial in biology as it allows substances to move across cell membranes, facilitating essential processes like nutrient uptake and waste removal.

Can you give me an example of diffusion in cells?

Sure! An example is the diffusion of oxygen from the lungs into the bloodstream, where it moves from an area of high concentration to low concentration.

How does temperature affect diffusion?

Temperature increases the kinetic energy of molecules, which speeds up diffusion. Higher temperatures generally lead to faster diffusion rates.

Are there any factors that can hinder diffusion?

Yes, factors like membrane permeability, concentration gradients, and the size of molecules can hinder diffusion.

What role does diffusion play in plant cells?

In plant cells, diffusion is vital for gas exchange, such as carbon dioxide entering for photosynthesis and oxygen exiting.
