Lab Report Testing the Effect of Light Intensity on the Rate of Photosynthisis
I'm going to investigate the amount of light used in photosynthisis to see if it
has a noticable effect when you increase or decrease the light intensity.
Photosynthisis is the way in which light and carbon-dioxide is used by a plant to
produce energy in the form of starch.
6CO + 6H O = C H O + 6O
The factors that effect the rate of photosynthisis are the amount of light, the
amount of carbon-dioxide (CO ) and the temperature that can be used by the plant. I
have already carried out the experiment to see the effects on a plant when you
change the amount of carbon-dioxide. I found that the more carbon-dioxide used the
faster the plant photosynthisied. To see if this rule (More of a limiting factor = The
quiker the rate of photosynthisis) works, I will plan a experiment . My experiment
will be to see if the light intensity follows this rule. I will use a aquatic plant as they
can be used to see the effects under water.These plants still cotain chlorophyll (a
light absorbing die thats converts light energy intochemical energy).
Aim
To see if the amount of light intensity will effect the rate of photosynsis.
Prediction
I predict that the more amount of light you allow the chlorophyll to absorb the
quicker the rate of photosynthisis will be. I think this because the amount of light is
a limiting factor in the reaction of photosynthisis. So if you alow more of a limiting
factor to be present in the chemical reaction it will all most certainly speed up the
rate of that reaction. If a plant had the right amount of carbon-dioxide and the right
temperature but the wrong amount of light the reaction of photosynthisis will be
slow. This is because the reaction needs the light to let the plant turn the light
Increasing the light intensity will make photosynthesis faster. Variables: In this experiment there are a few things we have to keep the same.
Carbon dioxide is necessary for plants to carry out the process of photosynthesis, which is an important process because it allows plants to produce glucose, as well as oxygen. Based on evidence from previous experiments, the growth of the plant will reflect the amount of CO2 gas that is present in the environment (O’Leary and Knecht 1986). This means that the plant growth relies on the carbon dioxide in the atmosphere in order to be successful. Therefore, in several cases, it has been noted that when the concentration of CO2 is doubled, the plant growth will similarly increase (Carter et al. 1997). So, it can be concluded that by raising the amount of carbon dioxide in an environment, the surrounding plants will experience an increase in growth.
Photosynthesis consists of the following equation: Sun light Carbon dioxide + Water = = == == ==> Glucose + Oxygen Chlorophyll Chlorophyll is a substance found in chloroplasts, found in the cells of leaves.
This chemical is used to catch the light energy needed in photosynthesis. They take carbon dioxide from the air. Plants use sunlight to turn water and carbon dioxide into glucose. Plants use glucose as food for energy and as a building block for growing. The way plants turn water and carbon dioxide into sugar is called photosynthesis.
The Effect of Light Intensity on the Rate of Oxygen Production in a Plant While Photosynthesis is Taking Place
= > [CH2O} + O2 + H2O, This shows that when the light intensity is increased the rate of reaction will be more quicker he only anomalous result there was, is the one in the 100 watt result the reading after 5 minutes is anomalous because it does not follow the predicted pattern of increasing in the production of gas because it is lower I know from my own knowledge of photosynthesise that when the light intensity is increased the rate of reaction will be more quicker because many plants and trees photosynthesise quicker in stronger light and photosynthesise slower in dimly lit places. The chlorophyll absorbs light energy and enables it to be used by the plant for building up sugar. The overall effect is that energy is transferred from sunlight to sugar molecules.
To make the test fair I will use the same amount of water and the leaf

Chlorophyll in the cells in the palisade layer absorb light for photosynthesis. The plant releases the oxygen created in photosynthesis back into the air but it uses or stores the glucose for energy, respiration, growth and repair. The leaves and plants are also specially adapted for photosynthesis in their structure and cell alignment.

the effect light has on the growth of pea plants. It will take place in an environment with controlled light, with equal amounts of plants being grown in the light and in the dark. All elements of the experiment other than light will be kept the same, such as amount of seeds in each pot, amount of soil in each pot and amount of water given to each plant each day. This will ensure a fair experiment. Prediction: I predict that in general, the plants grown in the light will grow better than those grown in the dark.
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.
Photosynthesis is a process in plants that converts light energy into chemical energy, which is stored in bonds of sugar. The process occurs in the chloroplasts, using chlorophyll. Photosynthesis takes place in green leaves. Glucose is made from the raw materials, carbon dioxide, water, light energy and oxygen is given off as a waste product. In these light-dependent reactions, energy is used to split electrons from suitable substances such as water, producing oxygen. In plants, sugars are produced by a later sequence of light-independent reactions called th...
Several factors have an impact at the rate of which the enzymatic reactions being to proceed. This can come under; temperature, pH levels, enzyme concentration and substrate concentration.
According to scientists, photosynthesis is “the process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water. Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a byproduct.” ("pho•to•syn•the•sis,")
Photosynthesis is the process in which living cells from plants and other organisms use sunlight to produce nutrients from carbon dioxide and water, the image below “Diagram of photosynthesis 1,” helps show this process. Photosynthesise generally creates oxygen as a by-product through the use of the green pigment, chlorophyll, found in the plant that helps this reaction occur. “Photosynthesis provides us with most of the oxygen we need in order to breathe. We, in turn, exhale the carbon dioxide needed by plants,” (factmonster,2017). This is able to show us why photosynthesis is so greatly needed to occur through plants in order to give one another essentials needed for continuity of life. “Plants perform photosynthesis because it generates the food and energy they need for growth and cellular respiration,” (photosynthesieeducation, 2016).
