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

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 hypertonic solution

Observing Osmosis in Potato Cells Planning Purpose: To observe the effect of osmosis on plant cells. Hypothesis: The higher the salt content of the water‚ the lower the mass of the potato. Variables: Independent: the salt percentage of the solution Dependent: the weight of the potato in grams Controlled: the amount of water the length of time between measurements the method of measuring the type of plant cells tested Equipment: (as seen on 2A Human Biology task sheet)

GLADSTONE ROAD AGRICULTURAL CENTRE CROP RESEARCH REPORT NO. 1 TUBER QUALITY AND YIELD OF FOUR SWEET POTATO VARIETIES EVALUATED DURING 2007 Kenneth VA Richardson Department of Agriculture Nassau‚ Bahamas November 2009 ABSTRACT A variety trial was conducted on four sweet potato varieties from April to October 2007 at the Gladstone Road Agricultural Centre. The variety ‘Six Weeks’‚ which is an early maturing variety with white flesh and high dry matter content‚ produced the highest marketable yield

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 of water across a selectively permeable membrane. In osmosis‚ water diffuses across the area of lower solute concentration to that of higher solute concentration until the solute concentrations of the environment and the cell are equal. Tonicity‚ which is the ability of a solution to gain or lose water due to osmosis‚ results in an environment that is isotonic‚

electrolytes on the potential difference in a voltaic cell Introduction When two electrodes made of different metals are connected together in a voltaic cell‚ the chemical energy present is converted into electrical energy and an electromotive force is generated. This force‚ called the electrode potential‚ is normally measured under standard conditions‚ which is 298K‚ 1 mol dm-3 solution for the electrolyte. However when one measures the electrode potential in a voltaic cell‚ the conditions are

eInvestigating water potential of swede The aim of our experiment was to investigate the water potential of swede and then use our results to help us determine the water potential of plant tissue. This overall flow of water from a dilute area of high water potential to a more concentrated solution of low water potential across a partially permeable membrane is called osmosis. I predicted that the swede cylinders which are put in a test tube with a low potential of sucrose solution would become

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
