OSMOSIS

Introduction: 

Osmosis is the spontaneous movement of solvent molecules through a semipermeable membrane into a region of higher solute concentration (hypertonic), in the direction that tends to equalize the solute concentrations on the two sides. We did this experiment to understand the osmosi.

Materials:

-Potato

-Knife

-Spatula

-Three watch glass

-Distily water

-Salt

-Pen

Objectives: 

- Know about the osmosis phenomena. 

- Understand the process of osmosis in plasmatic membranes.

Procedure: 

- Take the potato and cut it in three picies

- Put it every picie in a watch glass. 

- Take the spatula and make an small hole in the middle of each picie of potato. 

-The first potato is for control de experiment, in the second we put salt and in the third we put distilled water. 

Observations: 

-The first potato- the potato is dry. 

-The second potato- the potato is with more water. 

-The third potato-  the potato absorbs the water.
