The aim of this experiment is to investigate the movement of water into and out of plant cells by osmosis. The cells chosen for study will be taken from potato tubers as they provide a ready supply of uniform material. Any substance dissolved in water...
Aim My main aim in this experiment is to find out if osmosis occurs in a potato, and how it affect the potato in different molar solutions of sucrose and water. Apparatus 6 petri dishes û for all of the six solutions Marker pen û...
Aim My aim is to find out the percentage increase or decrease in mass (grams) of potato tube, placed in varying concentration of glucose. Prediction I predict that the potato chip will decrease more in mass in the stronger glucose solution. The Scientific theory of...
Experimental Lab 5: Diffusion and Osmosis Introduction In order for cells to maintain homeostasis, they must allow substances to move in and out of the cell. There are four different ways in which substances move across differentially permeable biological membranes, including simple diffusion, facilitated diffusion,...
DIFFUSION AND OSMOSIS Introduction It is important for the cell to have a way to separate the cytoplasm (inside of the cell) from the extra cellular materials (outside of the cell). This is accomplished by the cellular, or plasma, membrane. The plasma membrane is composed...
All cells have an outer protective casing, the cell membrane. It protects the cell from the outside world, but is also vital in the transfer of particles in and out of the cell. The cell membrane controls which particles can enter, and which particles can...
