Abstract: Water potential is the measure of free energy of water in a solution. The purpose of this lab was to find the water potential of a potato cell. The problem of this lab was‚ if there was a high molarity of solute‚ would it have a positive or negative water potential? The hypothesis of the experiment was‚ if there is a high molarity of solute then the water potential would be lower or negative. After obtaining potatoes‚ we cut them into pieces‚ weighed them‚ and then placed them in a solution

Investigating the Water Potential of a Potato. I have been asked to investigate the water potential of a potato. During my investigation I will not actually be able to measure a value for‚ as it is a pressure value (kPa). Osmosis is a special form of diffusion involving only water molecules. It is defined as "The passage of water from a region of high water potential to a region of low water potential through a partially permeable membrane" Definition of Water Potential. The potential for water to move

Osmosis and Water Potential Year 11 Emary Venter INTRODUCTION: The cell is the basic unit of living things‚ and is made up of multiple organelles. Organelles are membrane bound subdivisions‚ each specialised for a specific function. This experiment looks at the Plasma Membrane‚ which is a semipermeable layer surrounding the cell. It’s primary job is to control what goes in and out of the cell. Molecules can move across this membrane in either an active movement or a passive movement

My inference of the B. Rapa seeds was that they would most effectively react to the peat moss because of the high concentration of water. I reject my hypothesis on the basis that peat moss had the least positive productivity in the experiment. My results show that peat moss was the most unsuccessful in assisting the growth of each plant. Pods 1‚ 3‚ and 4 never broke through the soil‚ and remained at a depressing 0 centimeters the entire length of the experiment. The 2nd pod did grow slightly. It

Introduction Molecules are constantly in motion due to thermal energy. Therefore‚ the molecules will move around and bump into each other. Because of this‚ molecules tend to spread out evenly into available space in a process called diffusion. Diffusion is the random process of molecules moving from areas of high concentration to low concentration‚ thus requiring no energy. Many of the substances that enter or leave the cell do so through diffusion. Osmosis‚ a type of diffusion‚ is the movement

country. Its an eternal emotion that keeps us bound to value our native land and everything related to it i.e. our motherland. Its this emotion that brings unity among nations which is a positive consequence. Though there are few negative consequences of Nationalism as well. There are many positive consequences of Nationalism besides unity that is being united as a nation. In a nation there are various groups of people belonging to different spheres and circles of life having different cultures and traditions
