ratio on the rate of osmosis of Solanum tuberosum L._ BACKGROUND A cell needs to perform diffusion in order to survive. Substances‚ including water‚ ions‚ and molecules that are required for cellular activities‚ can enter and leave cells by a passive process such as diffusion. Diffusion is random movement of molecules in a net direction from a region of higher concentration to a region of lower concentration order to reach equilibrium. Diffusion does not require any energy input. Diffusion is needed

Sophie Murdock Osmosis Lab Osmosis in Plant Cells: Solution Initial Volume (mL) Final Volume (mL) Percent Change Distilled Water 0.8 1.0 125% 0.4% NaCl 0.5 0.8 160% 0.9% NaCl 0.6 0.8 133% 5% NaCl 0.6 0.5 83% 10% NaCl 0.6 0.5 83% 8. The cells in the solutions of distilled water‚ 0.4% NaCl‚ and 0.9% NaCl would all appear to be inflated and could burst. This is due to the fact that the solution is hypotonic to the potato‚ thus water is entering the cell. Meanwhile‚ the cells in the solutions

Osmosis Experiment Subject: Professor Egg-avier Duration: 3 weeks (Oct 2nd – Oct 16th) Week 1 On October 2nd my group was giving a raw egg (weighing 58.8 grams) and placed it into a clear mason jar with 200mL of vinegar. The ph levels of our vinegar equaled a 2 which tells us that vinegar is a fairly acidic liquid. Once submerged in the vinegar‚ little bubbles began to appear around the egg’s shell. We believed this to be carbon dioxide escaping from the shell. We left our egg to sit in the

Maple syrup was first collected and used by the indigenous peoples of North America. Vermont is the largest producer in the United States‚ generating about 5.5 percent of the global supply. Maple syrup is graded according to the Canada‚ United States‚ or Vermont scales based on its density and translucency. In the United States‚ a syrup must be made almost entirely from maple sap to be labelled as "maple". It is also used as an ingredient in baking‚ and as a sweetener or flavouring agent. Three
