- diffusion
- diffusion is the gradual movement of particles from places where there are lots of them to places where is fewer of them.
- natural tendency for stuff to spread out
- it happens in solutions and gasses- particles in the substances are free to move about randomly.
- simplest type is when gasses diffuse through eachother.

- natural tendency for stuff to spread out
- cell membranes
- hold cell together and let stuff in and out.
- dissolved substances can ove by diffusion

- dissolved substances can ove by diffusion
- things that can diffuse through (smaller)
- glucose
- oxygen (for respiration)
- amino acids
- water
- things that cant diffuse through (bigger)
- starch
- proteins
- particles flow through from a high concentration to a low concentration
- they move about randomly so go both ways
- if there is a lot more on one side theres a net movement on that side
- affected by
- light
- temperature
