How Light Intensity Affects the Photosynthesis of a Canadian Water Weed
Photosynthesis happens in all types of plants, whether on land or in
the water. Photosynthesis is a process that plants use every minute in
order to survive. They create the food that they need from Carbon
Dioxide and Water. Here is the full, balanced chemical equation;
[IMAGE]Carbon Dioxide + Water Oxygen + Glucose
CHLOROPHYLL
Or the chemical equation:
[IMAGE]6CO2 + 6H2O 6O2 + C6H12O6
With these equations, we are going to see that at what rates
photosynthesis happens in this Elodea.
We intend to use bulbs, to provide the ‘sunlight’ for our Elodea, if
we use any kind of filter, then we would use a blue filter, red filter
and yellow. We would not use the green filter, as that would turn the
light green. If we turn the light green then the green chlorophyll
would reflect the light. We would also have to control the temperature
in the beaker full of Elodea, as if the temperature increased too much
it would either denature the enzymes, ruining the experiment, or it
would make the photosynthesis rates increase massively. To prevent the
temperature from changing, one would place a beaker of water in
between the light bulb and the beaker of Elodea, so that the light
would only be able to alter the temperature of the beaker full of
water and not the Elodea one. To make this experiment fair, then you
should turn off the room’s lights, so that the plant only gets light
from our bulb. To stop the plant from getting unnatural Carbon
Dioxide, we must put sodium hydrocarbonate in the beaker to absorb it.
The reason why we did not take only one reason for each distance could
have resulted in me recording an anomaly. So we took

Investigating the Effect of Light Intensity on Photosynthesis in a Pondweed Aim: To investigate how the rate of photosynthesis changes at different light intensities, with a pondweed. Prediction: I predict that the oxygen bubbles will decrease when the lamp is further away from the measuring cylinder, because light intensity is a factor of photosynthesis. The plant may stop photosynthesising when the pondweed is at the furthest distance from the lamp (8cm). Without light, the plant will stop the photosynthesising process, because, light is a limited factor. However once a particular light intensity is reached the rate of photosynthesis stays constant, even if the light intensity is the greatest.

The Effect of Light on the Organic Plant Elodea Aim: To calculate the rate of photosynthesis from the number of oxygen bubbles produced by the plant. Photosynthesis: The process by which green plants use the sun's energy to build up carbohydrate reserves. Plants make their own organic food such as starch. Plants need Carbon dioxide, water, light and chlorophyll in order to make food; and starch and oxygen are produced. Carbon dioxide and water are the raw materials of photosynthesis.
Investigation Into the Colour of Light Needed to Start a Photosynthesis Reaction Diagrams [IMAGE] Method The apparatus for this experiment will be setup as shown in the diagram, for all the experiments the coloured filter will be 5cm away from the white light bulb, which is a 60watt bulb, and the beaker will be 20cm away from the edge of the coloured filter. Just before the experiment takes place we will place the pond weed (which has been in darkness for at least 24 hours to stop it any photosynthesis) into the beaker. I will then place the funnel over the pond weed and place the test-tube into the beaker (like the diagram above) I will then fill the beaker up with cold tap water till it covers the bottom of the test tube (450ml).

An Analysis and Evaluation of Data from Photosynthesis Experiments Graph analysis This is my analysis for the investigation in to the affect of light intensity on the rate of photosynthesis to the Canadian pondweed, elodea. In the results the pattern is that when the light intensity is higher the readings are generally higher. On the graph the less the light intensity the lower the gradient of the curve. the equation for the photosynthesis process is; CO2 + 2H2O + Light Energy = =

The Effect of Light Intensity on Photosynthesis Of Elodea Canadensis Introduction I wanted to find out how much the light intensity affected the Photosynthesis in Elodea Camadensa. I decided to do this by measuring the amount of oxygen created during photosynthesis. Photosynthesis is the procedure all plants go through to make food. This process uses Carbon dioxide, water and light energy. It produces Oxygen and Glucose.
Introduction: Photosynthesis uses the sun’s energy and uses it to convert carbon dioxide and water into sugar. There were two plants that stayed outside in the sunlight and two plants that were inside only receiving sunlight from the window. If the plants stay outside then they will grow at a faster rate and will be the tallest with most leaves because they receive more sunlight from the sun and have a fresher environment. Methods: Both the plants inside and outside were exposed to sunlight and given water every day. Results: The plants inside grew more than the plants inside. The plants outside did not last all of the weeks the experiment was being conducted.

An Experiment to Investigate the Effect of Light Intensity on the Rate of Photosynthesis. Introduction Photosynthetics take place in the chloroplasts of green plant cells. It can produce simple sugars using carbon dioxide and water causing the release of sugar and oxygen. The chemical equation of photosynthesis is: [ IMAGE ] 6CO 2 + 6H20 C 6 H12 O 6 + 6O2 It has been proven many times that plants need light to be able to photosynthesize, so you can say that without light the plant would neither photosynthesize nor survive.
Investigating the Effect of Light Intensity on the Size of a Plantain Leaf Title: To investigate the effect of light intensity on the size of a plantain leaf. Hypothesis: I predict that the size of the plantain leaves would increase as the light intensity decreases. Therefore, plantain leaves found in the shade will have larger surface areas than leaves found in an open area. Theory: Sunlight is an essential factor need to complete the process of photosynthesis.
Light is a very important factor in the rate of photosynthesis, in my project I am going to test that plants do need light in order to photosynthesise. It will be very interesting to see how light will influence the rate of photosynthesis in plants and what will happen if they do not get the required light in order to produce starch .
