Photosynthesis Investigation Research Question How does length of pondweed affect the amount of bubbles produced in 2 minutes by pondweed during the process of photosynthesis? Independent variable: Length of pondweed (8/10/12 cm). Dependent variables: amount of bubbles produced in 2 minutes. Control variables: Volume of water in the beaker (500ml)‚ The volume of water has to be the same every time‚ so when doing the experiment I need to make sure I always use these 500 ml that i have already

Introduction Photosynthesis takes place in the chloroplast and is the use of sunlight energy for cell processes. It happens through a number of chemical reactions and the transfer of electrons. It is used as the source of energy (ATP) for plants. The reaction equation for photosynthesis is H2O + CO2 + (Light) (CH2O)N + CO2 In the Hill reaction‚ Robert Hill showed how chloroplasts in water can still function if there is light and an electron acceptor to release oxygen. He proved that the oxygen

contained in a liter of water. If you put these organisms in a bottle and turn on the lights‚ you get photosynthesis. If you turn off the lights‚ you turn off the primary production. Darkness has no effect on respiration. This is because cellular respiration is actually the reverse process of photosynthesis. Oxygen is a necessity of life requirements for basically all living organisms.* In this lab we are testing how different levels of salinity in the water indirectly affects the gross primary productivity

of the specialized underlying structures of these life-forms. In order for us to appreciate these special adaptation‚ we first need to know how a typical plant or an animal cell organelle behaves in different water and solute concentrations. In this lab‚ we will determine the effects of hypertonic‚ isotonic and hypotonic solutions on plant and animal cells. In general when an animals cell’s placed in hypertonic solution it shrivels; a plant cell on the other hand undergoes plasmolysis. When an animal

INVESTIGATING FACTORS AFECTING THE RATE OF PHOTOSYNTHESIS! Testing Carbon Dioxide Done by: Krish S. AIM: is to plan and carry out an investigation on factors affecting the rate of photosynthesis. We are doing this by investigating the amount of bubbles produced by waterweed to show the rate of photosynthesis and the effects of carbon dioxide (CO2). HYPOTHESIS: I think that the rate of photosynthesis will increase as the rate of CO2 increases this can be seen by the bubbles produced from

Relevant to: 2.5.2. Describe photosynthesis in terms of inputs‚ outputs and energy transformations. Criteria to be assessed: PL‚ DCP‚ DEC. Background: Photosynthesis is the reaction carried out by green plants to produce a supply of food. The reactions occur in the chloroplasts and require light energy. 6CO2 + 6H2O C6H12O6 + 6O2 In aquatic plants‚ the production of oxygen can be used to measure the rate of photosynthesis as the oxygen bubbles can
