B. Discussion1. Activity IOn this activity we used egg as sample that we want observe the move of liquid subtences of the egg. Based on observation we can found the final result for all concetration of NaCl solution is 3mm (0.2%), 5mm (0.4%), 4mm (0.8%), 2mm (1%), 6mm (2%), 8mm (4%).Based on observation we can found that NaCl is hipotonis, that cause the NaCl is move into the egg through the membrane and the liquid of the egg is move out trhough the straw. On our data is there is the mistake and not support the theory. It should be the more low concetration of NaCl, the higher liquid of egg is out. This is based on theory that we know if the solution will do osmosis from the low concentration to the high concentration because the water potential on low concetration is higher than the high concentration. Our mistakes maybe because the size of membrane is not same2. Activity IIOn this activity we used the ventral skin and dorsal skin from frog to observe the osmotic activity. As we know the frog can breath with the skin. It mean the skin of frog is semipermeable.Based on observation, we can found the final result is dorsal (4%) is 4mm and ventral (5%). Based on theory in the osmotic activity, the distiled water will move into NaCl through the semipermeable skin of frog because the the distiled water or aquades is have higher water potential than the NaCl solution
3. Activity IIIThis observation using the intestines of chickens to observe the events of osmosis. Observations made during the 24 hours by taking a 30-minute time interval. .. Based on the final results of the retrieval of data obtained for Aqueous NaCl; 6%, 8% respectively are 9 mm and 6 mm. it is in accordance with the theories expressed by Wulangi (1993), that a solution that has a low concentration, then the higher water potential. As does the opposite, when a solution has a concentration of high potential value the water is getting lower. Thus, if a solution has a high concentration of water potential values, lower. So the switch is aquades or distilled water into a tube containing a solution of NaCl which increase the volume of water in test tubes.
