How does temperature affect osmosis in a potato? If temperature increase then the osmosis rate will be faster because water molecules will move quicker crossing the membrane of potatoes.
WebThrough osmosis, the solution moved along the concentration gradient and into the potato slice making it hypotonic. When there were higher concentrations of sucrose solution, the potato decreased in weight. This is due to the fact that the potato was hypertonic in comparison to the potato. WebIn osmosis lab, the dependent variable is the length of the potato. The controlled variables are the amount of water, amount of salt, and the size of the potato. If the potato is placed in a higher salt concentration, then the potato will decrease its size. We started the lab by cutting the potato core length (44 mm).
