muscle movement and certain cell reactions are reliant on energy the transport of oxygen to the cells of tissues and organs by blood vessels is vital for respiration to occur. Oxygen is carried in red blood cells by the pigment haemoglobin‚ a globular protein consisting of four polypeptide chains. Both of these components of blood are structured specifically to carry out their functions of oxygen transport‚ hence ensuring efficient respiration. Erythrocytes‚ or red blood cells‚ possess a unique structure

GCSE Biology: Osmosis in a Potato Aim To investigate the effect of placing a piece of potato in a given strength of sugar solution. Prediction I predict that‚ as the solution becomes more concentrated the more the cell will shrink‚ as the water‚ of higher concentration inside the potato cells‚ flows down a concentration gradient into the solution‚ which has a lower concentration of water molecules. If we say that the percentage change when the potato is placed in the 1M solution is x%. I predict
Premium Measurement Potato Concentration
Osmosis in potato cells Aim: To view and examine the effect different concentrations of sucrose solution has on the movement of water across the cell membrane. Hypothesis: That the potatoes will either increase or decrease in mass‚ due to the effect of the different concentrations. Osmosis will occur. Apparatus: * Fresh potatoes * Apple corer * Scalpel * Petri dishes X 10 * 50ml measuring cylinder * Distilled water * Paper towelling * Sucrose solutions:

increase in size as their cells grow and divide. Almost all cells complete a full cell cycle that includes interphase and cell division. In interphase‚ cells serve their specialized functions‚ grow‚ and copy their genetic material. Mitosis is the first stage of cell division‚ in which the copied chromosomes are separated into two new nuclei. Then in cytokinesis the cell divides into two daughter cells. If no mutations or errors occur‚ the genetic material in each daughter cell is identical to what was

Block 2 LAB REPORT OUTLINE FOR DIFFUSION/OSMOSIS LAB Introduction: Diffusion is the net movement of small or uncharged molecules or substances from areas of higher concentration to areas of lower concentration. There is simple diffusion‚ as explained‚ and facilitated diffusion. Facilitated diffusion‚ on the other hand‚ involves larger or charged molecules or substances that need a protein tunnel through the membrane to help the substance enter and leave the cell. Since the substance will move in its
