Movement through the membrane

Movement Through the Membrane

Mr. Luis A. Velázquez

Academic Biology


Diffusion

Diffusion

DiffusionMotion of particle for high concentration

To low concentration. This causes many substances

to move across a cell membrane but does

not require energy.


Movement through the membrane

What is Osmosis?

Osmosis is a type of diffusion.

The movement of water across a semi permeable membrane.

Osmosis is the movement of water through a semi permeable membrane to a higher concentration of solutes .


Passive transport

Passive Transport

  • When material move from areas of high concentration to low concentration they don’t requires energy.

    • Examples

      • Diffusion

      • Facilitate Diffusion

      • Osmosis

Particles

Water


Active transport

Active Transport

  • When material move from areas of low concentration to high concentration they requires energy.
