hai readers, sekarang saya akan membagi bagikan ilmu nih heheheh =D, dari judul ajak udah gitu ya. dari pada berlama lama lagi ini dia

Osmosis in Potatoes

what you Need

·       1.    2 match sized slices in potato

·       2.   2 small plastis bowls

·      3.   Tape

·      4.   Salt

·        5. A plastic tea spoon

·       6.   Water

·        7. Student worksheert

What to do

1.   By using a scalpel, have two match sized slices of potato

2.   Press with your fingers to feel the hardness of the potato. Write your observation in the table provided

3.   Fill one plastic bowl with water. The height of the water is about half of the bowl and mark with a sign A an the bowl with tape. Put 1 slices of the potato in it

4.   Now fill the other plastic bowl with water and 2 teaspoon of salt and mark with a sign B

5.   Leave it a day ang a naight. In the following day, take each potato slice out and feel the hardness by your hand

6.   Are the two of the same hardness ? write your observation result in following observation table and explain.

Observational data

a piece of potato	The level of violence potato pieces
	Before soaking	After soaking
A	hard	harder
	Length: 4 cm	Length: 4.2 cm
B	hard	soft
	Length: 4 cm	Length: 3.8 cm (shrink)

 

after being soaked, a piece of potato A harder than a piece of potato B, causes a piece of potato A harder Because water is easy to go through the potato skin cells.

Conclusion 

Osmosis is the entry solution potatoes into potato endodermis cells. In the body of a multicellular organism, the water moves from one cell to another with ease. Besides water, the molecules are small such as O2 and CO2 are also easily pass through the skin cells. The molecules will diffuse from areas of high concentration to low concentration. Skin cells allows water molecules pass faster than dissolved elements, the primary cell walls of the porous against both. Skin cells allows ongoing osmosis plant, but the solid cell walls that is causing pressure.
