Introduction.
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 .
The plant I have chosen to do is a Geranium which is a dicotyledonous plant found in the dry and hot regions of South Africa.
Aim
To see whether light effects the rate of Photosynthesis in plants or not.
Research Hypothesis.
Photosynthesis will occur at a faster rate when the plant is exposed to the sun, than when it is not exposed to sunlight.
I chose to test the effect light has on plants because it is very interesting to test that light is a very important factor, and as the earth gets hotter it will be interesting to see what will happen at the end while sunlight is important at the moment and is a core ingredient for photosynthesis, it will also be very interesting to see what would happen if the plants had no exposure to sun at all, and if they would adapt.

Plant Photosynthesis.
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...

...ed out very well as the plant I tested was correctly done, and it had a band that was yellow/brown where there was no starch present, the same leaf had a black boarder where the paper/foil was not placed, this was black because photosynthesis had occurred and produced starch. Therefore showing that light along with the other core ingredients are important factors for photosynthesis to take place successfully.

Increasing the light intensity will make photosynthesis faster. Variables: In this experiment there are a few things we have to keep the same.
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.
Both starch and sucrose can be converted back into glucose and used in respiration. Photosynthesis happens in the mesophyll cell of leaves. There are two kinds of mesophyll cells - palisade mesophyll and spongy mesophyll. The mesophyll cells contain tiny bodies called chloroplasts which contain a green chemical called chlorophyll.
Experiment #1: The purpose of this experiment is to investigate the effects of baking soda and light intensity on the rate of photosynthesis of green spinach leave through the observation of floating disk.
It can be concluded that chloroplast is responsible for photosynthesis, with blue light forming the highest rate of photosynthetic activity. The widespread use of coloured netting in the future could result in indoor plant growth that is unreliant on weather, and the ease of the production of crops with the desirable phenotypes. However, future research is still required to eradicate any unknown data and determine plant responses in relation to wavelength
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.
The process of photosynthesis is present in both prokaryotic and eukaryotic cells and is the process in which cells transform energy in the form of light from the sun into chemical energy in the form of organic compounds and gaseous oxygen (See Equation Below). In photosynthesis, water is oxidized to gaseous oxygen and carbon dioxide is reduced to glucose. Furthermore, photosynthesis is an anabolic process, or in other words is a metabolism that is associated with the construction of large molecules such as glucose. The process of photosynthesis occurs in two steps: light reactions and the Calvin cycle. The light reactions of photosynthesis take place in the thylakoid membrane and use the energy from the sun to produce ATP and NADPH2. The Calvin cycle takes place in the stroma of the chloroplast and consumes ATP and NADPH2 to reduce carbon dioxide to a sugar.
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.
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.
= My hypothesis is to determine factors which might affect the stomatal opening in leaves. A practical experiment can easily be set up to determine these factors. The following procedure should be followed: Select a plant that has been kept in the light and label the container e.g. "LIGHT." Clip two leaves from this plant.
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.
= I predict that the parts of the plants will absorb more sunshine, leaving a bigger quantity of leaves and a larger surface area of branches.
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 a cycle plants go through converting light into chemical energy for use later. Photosynthesis starts in the chloroplasts, they capture chlorophyll, an important chemical needed for photosynthesis. Chloroplasts also take water, carbon dioxide, oxygen and glucose. The chlorophyll is taken to the stroma, where carbon dioxide and water mix together to make
