Biology Coursework ¡V Does The Light Intensity Affect the Rate of Photosynthesis The Investigation In this experiment I will investigate the affect in which the light intensity will have on a plants photosynthesis process. This will be done by measuring the bubbles of oxygen and having a bulb for the light intensity variable. Variables The input variable which will be used in this investigation will be the light intensity (this will be a 100Watt bulb being moved closer and further away from

The effect of light quantity on photosynthesis of green land plants Introduction Photosynthesis is the process of converting light energy into chemical energy (Hoober 1984). Pigments within chloroplasts‚ primarily chlorophyll‚ absorb the incoming solar energy which excites their electrons (Hoober 1984). These pigments exist in photosystems in the thylakoid membrane of the chloroplast (Ladiges et al.2010). As the electrons return to ground level‚ they are captured by the electron acceptor in the

Determining Rates of Photosynthesis Through Chloroplasts Introduction: 1)Background= 2) Purpose= measure the rate of photosynthesis in chloroplasts. 3) The chloroplast will be subjected to two experimental conditions- light‚ and the absence of light‚ using a spectrophotometer to determine the amount of DPIP reduced at specific time intervals under each condition. 4) I predict the amount of DPIP reduced will vary for each condition and increase over the time intervals. I hypothesize

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

6.1 Overview of Photosynthesis 6.1.1 Identify the cellular structures where photosynthesis occurs. A: It occurs in plants inside of the chloroplast 6.1.2 Locate the structures within a chloroplast and list their functions. A: A double membrane surrounds a fluid-filled area called the stroma. A third membrane system within the stroma forms flattened stacks called thylakoids‚ which in some places are stacked to from grana. The space within each thylakoid is believed to be connected to the space

How does light intensity affect the rate of photosynthesis? Poorly Pondweed Questions 1) How does light intensity affect the rate of photosynthesis? 2) How does temperature affect the rate of photosynthesis? sunlight carbon dioxide + water glucose + oxygen chlorophyll sunlight 6CO2 + 6H2O àààààà C6H12O6 + 602 chlorophyll Prediction I predict that the more intense the light‚ the higher the rate of photosynthesis. To photosynthesise‚ plants need light. It provides the energy for the process

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

The plant will not be affected by the heat and due to my previous research it will result in faster rate of photosynthesis and plant will survive longer. Each of my experiments will be 60 seconds long to get decent measurable results. The light source I will be using has a voltage of 35V and will have a beaker of water in front of it‚ and 15cm away front he end of
