As Elodea is a pond plant, the oxygen given off can … ALPS lesson with a selection of experiments to investigate the effect different factors such as light intensity, colour, temp and pH have on the rate of photosynthesis. This will be because a longer elodea may mean more leaves, which provides a larger surface area in total, allowing more light to be absorbed, therefore increasing the rate of photosynthesis. Bestsellers. Extracts from this document... Introduction. To calculate the rate of photosynthesis by measuring the number of oxygen bubbles produced in 30 second intervals. This increase follows Vant Hoffs law. This means that when the concentration of X was increased from experiment 20 to experiment 21, the rate of Z production didn't increase. Now the intensity of light is increased and the rate of photosynthesis … Use any method you like. Limiting Factors There are 3 factors which can limit the rate of photosynthesis. Plants tend  to grow quicker (and hence photosynthesise faster) in the summer when the weather is warm and there is a lot of sun The rate  of photosynthesis will be limited if light, … Directions: 1.

Some greenhouses use oil burners or C02 from nearby gas power stations. Photosynthesis: Limiting Factors Purpose: 1. tension probably limiting; 3 (ii) lower rate of photosynthesis overall in A; limiting effect in A starts at lower light intensity; lower rate of photosynthesis in A when CO 2 is limiting; 3 (c) I A = 1 ; = 1.778 ; I B = 1 ; = 4.0; 4 0.752 0.502 TOTAL 15 QUESTIONSHEET 6 (a) A - carbon dioxide; B - ADP; C - NADP; (B and C could be … According to this law the rate of chemical reaction doubles for every rise of 10°C. The concentration of CO 2 is increased until the rate of photosynthesis becomes constant. The first … Tags: A-level, biology, experiment, factors affecting the rate of photosynthesis, project. … According to this law, when a process depends on a number of factors, its rate is limited by the pace of the slowest factor. A limiting factor. Sign In Join. Limiting leaves to 10 does not directly determine the number of elodea cells which may affect the rate of photosynthesis. (C) The readings show that the rate of photosynthesis is the highest in red light and lowest in green. Directions. This experiment is going to show how light intensity affects the rate of photosynthesis in Canadian Pond Weed, Elodea. en Change Language. Level. • Formulate a reasonable hypothesis.
