Speeding up the Rate of Photosynthesis
Outline: The aim of my experiment is to find a factor that will speed
up the rate of photosynthesis. Photosynthesis need light to work, so
light therefore should speed up the rate of photosynthesis. I will do
an experiment to see if this works. I will place a piece of cut
pondweed into a beaker containing water and sodium hydrogen carbonate.
A lamp will be shined on to the pondweed and the amount of bubbles
released from the plant will be counted. The lamp will be adjusted to
different distances from the plant to try and obtain different
results.
Light
The equation for photosynthesis is:
Chlorophyll
[IMAGE]Carbon Dioxide + water Glucose + oxygen
Method
First of all I collected all my apparatus. Then I filled both the
beaker and the measuring cylinder with water. The pondweed was put
inside the measuring cylinder, with a paper clip on one end to weigh
it down. I then added sodium hydrogen to the water in the measuring
cylinder to make sure that the amount of CO2 was kept constant through
the experiment. The beaker full of water was used as a heat shield,
which was placed halfway between the bench lamp and the pondweed every
time. Once I had all my apparatus set up I was ready to start the
experiment, I had a results table ready to fill in as the experiment
was being carried out. Once I had finished each distance I repeated it
again to try and get as accurate as results as possible.

Variables
Independent variable: The independent variable is what you are going
to change throughout the experiment; in this case it is the light
intensity.
Dependant variable: The dependant variable is what you measure or

The key to keeping any task, especially this one, flowing smoothly is gathering all the materials so they are within reach. Having the materials near helps the process go by quickly, for you are not constantly stopping to search for materials needed at that time.
Autotrophs, can build organic compounds from simple molecules such as water and carbon dioxide and their type of feeding is called autotrophic nutrition. While they are building complex molecules, they need large amounts of energy. They are divided into two groups according to their source of energy: chemoautotrophs and photoautotrophs. Chemoautotrophs can synthesize organic compounds from CO₂ AND H₂O by using inorganic oxidation energy and they do not require sunlight. However, photoautotrophs, including green plants, produce sugar and O₂ from CO₂ and H₂O by using sunlight. The green pigment which absorbs the light is called chlorophyll and this process is called photosynthesis.
Before beginning this program, warm up by doing light activity such as riding a stationary bike for 5-10 minutes.
On the first day, I went for about twenty minutes before cracking a joke at my best friend. It wasn't anything out of the ordinary for me, but I actually stopped and thought about the possible consequences of my actions. Breakthrough! I went for another twenty minutes, most likely, before making some sort of snide comment, though. Oops.

To make the test fair I will use the same amount of water and the leaf
Photosynthesis is a series of light driven reactions that convert energy poor compounds such as carbon dioxide and water to energy rich sugars [1] such as glucose. The process generate an electron gradient across the membrane of a chloroplast, which is used for ATP synthesis, and simultaneously produces electrons used to make NADPH, using NADP+ as an energy carrier[2]. Crudely put, it is the method by which autotrophic plants make their own ‘food.’
There are lots of natural processes constantly happening all around us, these processes are often linked by passing one type of atom to the next process which passes the same atom to the next one and so on. This ‘passing of the atom’ along a chain of processes is called a cycle, the series of processes in which the carbon atom goes through is called the carbon cycle. Each Carbon is the fourth most affluent element in the universe and is an important part of most molecules that make up most of the world’s natural resources and organic matter, which is why the carbon cycle is one of the most important cycles on earth. Through-out the cycle, carbon can become several different forms such as sugar, oil, diamond and marble. Processes such as photosynthesis, combustion and the compression of the earth play key roles in changing, containing and releasing carbon. All the chemical reactions and processes and forms carbon creates are part of the carbon cycle, which is one of the most important cycle on earth. The majority of carbon on earth is in the atmosphere the rest is stored in rocks, fossil fuels, oceans, plants and soil. Carbon is constantly being added to the atmosphere, the most common forms being carbon dioxide and methane gas. At the same time it’s being removed by plants on land and in the oceans. Carbon can be stored for hundreds of years in sediment, fossil fuels, rocks and the ocean. The carbon in the atmosphere is almost always a compound called carbon dioxide.

Create oxygen. Photosynthesis is very important because without it we would die of lack of
Photosynthesis is a key contributor to all living things; photosynthesis provides the oxygen, food, and nutrients that help all living things stay healthy and alive. Photosynthesis converts solar energy into the chemical energy of a carbohydrate. Photosynthetic organisms, including land plants, algae, and cyanobacteria, which are called autotroph...
