Aim: How does Osmosis and Diffusion compare? Como comparamos la difusion y la osmosis?

Osmosis- La difusion de agua

OSMOSIS  The movement of water from an area of high concentration to an area of less concentration.  Movimiento de agua desde un area de alta concentracion a un area con baja concentracion.

Which container has a greater concentration of water molecules? Que embase tiene una mayor concentracion de agua? = Solute (salt) Soluto (sal) = Solvent (water) Solvente (agua)

In which direction is osmosis going to occur? En que direccion va a ocurrir la osmosis? = Solute (sugar)= Solvent (water) Selectively Permeable/ selectivamente Permeable

Concentration Differences: 1 ) A 90% salt solution vs. a 20% salt solution. Una solucion de 90% de sal vs una solucion de 20% de sal. 2)A 60% salt solution vs. 80% salt solution? Una solucion de 60% se sal Vs una solucion de 80% de sal.

Why does this happen?

Why are the water molecules diffusing to the left? Water molecules are red

 The water is moving from an area of high to low!/ El agua se mueve de una concentracion alta a una concentracion baja.

What happens to an animal cell if it is surrounded by a low concentration of water? Que le pasa a una celula animal si esta rodeada de una concentracion baja de agua? The Cell will shrink!! La celula pierde agua y disminuye en tamano

In which direction will osmosis happen? En que direccion va a ocurrir la osmosis?
