Abstract: the group conducted a lab for a day in the lab the group used 6 test tubes in which there was different salt concentration there was no salt in the first test tube, the second one had 02 molars, the third one had 04 molars, the fourth one had 06 molars, the fifth one had 08 molars, and the sixth one had 10 molar the group put 3 chunks of potatoes in each one of them. For lab 2, the potato in a 10 m concentration would gain more mass through osmosis than the potatoes in solutions with lower glucose concentrations methods this study was conducted in mrs wootton’s room at new tech high @ coppell, on september 4th and 8th, 2015. This research will begin with the statement that all living organisms including plants and animals have evolved from the simplest unicellular organisms like the planktons and amoebae to the much more complex living forms with intricate cellular differentiation and organization.
Because of osmosis, the cells of the potato surrounding the salt filled cavity gave out water into the cavity this water is drawn from the water lying in the tray the cooked potato cells are.
