Osmosis and Diffusion (Nunu)

Hypertonic Solution Is when the molecules outside of the cell are higher than the concentration in cytosol. Ensure has more nutrients than water.

Diffusion is the movement of particles from an area of high concentration to an area of low concentration. When I spray my "smell good" on me every morning, particles are first bonded together then the molecules soon distribute evenly, causing a state of equilibrium to exist.

This is an example of Passive Transport because I'm not giving the jar energy

The Semi-Permeable acts like a gate keeper by allowing certain molecules through

A Hypotonic Solution is when the molecules outside the cell are lower than the concentration in the cytosol. By having more solvent than solute it is therefore a Hypotonic Solution.

Osmosis and Diffusion (Ariel Chapman)

Hypertonic : The food coloring on the outside haven't entered the cell membrane to change the color of the egg. The solution of the food coloring would change from a high concentration solution to a low concentration solution once entered the cell membrane. (picture 1)
Hypotonic : All the ingredients that's mixed in the vinegar is equally shared in the mixture until equilibrium is established. (picture 2)
Diffusion : The movement of molecules from an area of higher to an area of lower concentration without any energy input. Diffusion will eventually cause the concentration of molecules to be the same throughout the space the molecules occupy, causing a state of equilibrium. The smell of the perfume will eventually spread throughout the room equally. (picture 3)
Osmosis : The eggs are in a solution of vinegar. In a few days the vinegar will eventually enter the cell membrane and the solution will go from high concentration to a low concentration solution. (picture 4)
Semi-permeable : The window screen allows certain substances to be transfered  into and out the window. (picture 5)

Osmosis and Diffusion (Tiffany Ben)

A hypertonic solution is when the molecules outside the cell have a higher concentration of cyotsol. the mixture being made (Bottom) will be poured in the jar w\full of eggs. the eggs will absorb the solution and will cause the eggs to pickle.


A Semi Permeable Membrane only allows certain things to enter into the cell. The wire that is inside the window in schools is a great representation of a semi permeable membrane. It allows only small things to get threw, in others words it is a filter. 


Osmosis is the movement of water molecules across the membrane. The eggs were submerged in a vinegar solution. In a couple days the eggs will be pickled showing how the water molecules spread across the eggs membrane.


Diffusion is the movement of particles from high concentration to low concentration.
The solution is infused with red food coloring. The longer the eggs are submerged in the solution the more the color that will take to the egg.


A hypotonic solution has a low concentration of cytosol. This means that it has more solvent in it. the bowl is filled with solvent and contains a non semi permeable membrane.
