find the concentration (mole/dm3 (M)) of solute in a potato cell by using the process of osmosis and different concentrations of sucrose solution. Background information Osmosis is diffusion of water across a partially permeable membrane. It moves from a solution with less solute concentration (high water potential) to a solution with more solute concentration (low water potential). The one with a high water concentration is called a hypotonic solution and the low water concentration is called

Aim: To investigate the effect to the potato cells in the different solute concentration water Introduction; Water can move through the different cells due to the difference of water potentials in the cells. If there is a higher solute concentration in the cell than outside the cell‚ the water will move into the cell. However‚ if the concentration of inside the cell is lower than the outside‚ water will not move into the cell. This process is called osmosis. Research question; This investigation

Determination of an Electrochemical Series In electrochemistry‚ a voltaic cell is a specially prepared system in which an oxidation-reduction reaction occurs spontaneously. This spontaneous reaction produces an easily measured electrical potential which has a positive value. Voltaic cells have a variety of uses and you commonly refer to them as a “battery”. Half-cells are normally produced by placing a piece of metal into a solution containing a cation of the metal (e.g.‚ Cu metal in a solution

Identify and describe the composition of the fluid compartments within the body Either Intracellular fluid (ICF- 2/3 of the body’s water) or extracellular fluid (ECF -one third of the body’s water). The two main extracellular fluid compartments are the interstitial fluid and the intravascular fluid‚ which is the blood plasma. Other ECF compartments include the lymph and

------------------------------------------------- Water and Electrolytes Water constitutes 50-55% of a woman’s body weight and 55-60% of man’s weight. Water gives structure and form to the body‚ helps maintain body temperature‚ and also creates the necessary environment for cell metabolism. There are two compartments of body water‚ extracellular and intracellular fluid. Extracellular fluid (ECF) is water found outside of cells. Making up approximately 20% of total body weight‚ the ECF consists

Introduction: This experiment was used to examine the hypothesis that: Osmosis is dependent on the concentrations of the substances involved. Diffusion is the passage of solute molecules from an area of high concentration to an area of low concentration (Campbell & Reece‚ 2005). An example is ammonia diffusing throughout a room. A solute is one of two components in a chemical solution. The solute is the substance dissolved in the solution. The solvent‚ the other component‚ is any liquid in

The Potential of Pericytes Found in Blood Vessels Do pericytes found in blood vessels create more potential for adult stem cell research? The capability to revert blindness‚ cure diabetes‚ let paralyzed people walk again‚ replace deficient organs with newly grown ones and cure blood diseases are a few of the many potential functions of stem cells. A stem cell is an unspecialized cell that can develop into many different cell types in the body during early life and growth
