How light intensity affects the rate of photosynthesis The aim of my experiment was to determine whether intensity of light would affect the rate of photosynthesis in a plant. To do this, I placed a piece of Canadian pondweed in varying light intensities, and observed the amount of oxygen being given off. I used Canadian pondweed because of its unusual quality of giving off bubbles of gas from a cut end, when placed in water. Introduction Photosynthesis occurs only in the presence of light, and takes place in the chloroplasts...

an average. To extend my enquiries into the rate of photosynthesis, I
could perhaps try to link in some of the other limiting factors to the
same experiment, as well as investigating them in their own right. It
could also be interesting to explore the effects of coloured lights on the
rate of photosynthesis, which could lead to the question of whether or not
other types of light, such as fluorescent lights or halogen lights, would
have a different effect on the rate of photosynthesis.
The Respiratory System Organs involved are lungs, capillaries The body requires oxygen to survive as it feeds muscles, tissues, and organs. The air we inhale breathe in into our bodied consists of: GAS AIR INHALED AIR EXHALED Oxygen 21% 16% Carbon Dioxide 0.04% 4% ...

Introduction Osmosis is defined as the diffusion of water molecules, down a water potential gradient, across a partially permeable membrane. If the solutions on each side of the partially permeable membrane are equally concentrated then there will be no net movement of water across the membrane. If the solution...

Investigation For this experiment we plan to investigate the effect of varying concentration of a certain sugar solution on the amount of osmotic activity between the solution and a potato core of a given size. Osmosis is defined as the net movement of water or any other...

I will measure the volume of gas produced as the catalase in the potato tissue reacts with the hydrogen peroxide to create water and oxygen. I will change the temperature at which the reaction takes place, but to make the test a fair one I will keep the pH level...
