Cell transport

Question 1

What is diffusion?

Answer 1

diffusion is the movement of particles from an area of high to low concentration until all the particles are evenly distributed.

Question 2

What are some factors that affect the rate of diffusion?

Answer 2

temperature
distance
surface area
size of particles

Question 3

Examples of diffusion in living organisms

Answer 3

helps to maintain homeostasis by allowing efficient substances to move across membranes and within tissues
during respiration when carbon dioxide and oxygen reaches the cells and are removed by diffusion.
Water diffuses into the roots of the plants for photosynthesis.
carbon dioxide diffuses into the plant cells and oxygen diffuses out for photosynthess
