    In our Mediaphys Lesson I learned that the primary structure of a cell membrane is made up of a double layer of phospholipids molecules. The hydrophilic heads of the phospholipid molecules face outwards towards the water base solutions inside and outside the cell. The membrane is also made up of proteins‚ carbohydrate molecules‚ and cholesterol that form gates and pores‚ cell recognition‚ and stability. Active transport is used when a cell needs a substance to cross the membrane against its concentration

    of this lab‚ we will be focused on simple and osmosis. Simple diffusion and osmosis are vital for the diffusion of water and maintaining homeostasis. Homeostasis is the ability to maintain equilibrium and keep the organism alive. For example‚ if a cell is placed in a hypotonic solution there is more water inside the cell that outside which will cause water to diffuse out in attempt to reach equilibrium. Hypertonic solutions are when there is more water outside
