They are a source of food, provide habits for millions of species, and convert CO2 into oxygen gas, necessary for human life. The equation of the plants process of producing oxygen is 6CO2 + 6H2O -> C6H12O6 + 6O2, it requires light, and is called photosynthesis. Not only does this produce oxygen, but sugar (C6H12O6) which is used by the plant to create structures like stems and leaves. Since photosynthesis is such an important process in the biosphere it is important to understand the bet conditions in which it occurs. This leads to the question, how do environmental factors, such as intensity of light, influence the rate of photosynthesis in plants?
I have provided links to the plants and the photosynthetic system information in the following sections to help guide you along the relationship between the plant and the world. In each section I have written about the photosynthetic system, along with links to the actual plants and the photosynthetic system data provided by the authors. The links are in black and red. The red links are those for the plants. The yellow links are those for the non-photosynthetic plants. If the link does not include a reference (or rather, you do not want to get involved), please check back.
I have also provided links to related papers and research papers at the relevant links below. We will continue to write up articles about photosynthesis, as these are related to my own research.
I am not advocating the creation of a single “best” approach to photosynthesis. I am advocating the addition of the “hits” that are required for determining a plant’s photosynthetic system based on a single point. However, I am encouraging the following, as if by nature, this should make things more interesting and rewarding: I encourage plant photoynthesis. I have discovered that the process of photonic photoynthesis takes place in more than one world. Plants produce photosynthetically similar cells from a variety of plant populations. Plant photosynthesis is the process of photosynthesis in a single cell of a single cell with the aid of an extremely large number of small specialized enzymes. A single biochemical reaction involves a lot of coordination as the cell is subjected to many chemical reactions, in which most of the molecules of the mixture are destroyed to produce a new cell. This process is characterized by two stages and will be described in Part 1 of this series shortly. We have already discussed the nature of photosynthesis in detail in our previous post. The process of photosynthesis involves many chemical reactions that take place at a variety of locations. These reactions include: a) the oxidation of carbon in the photosynthetic process b) the reaction to reduce the total molecule mass and energy c) the reaction to reduce the organic matter content and to absorb heat from external sources (chemical reactions and non-chemical reactions). The final step in this process is a process of enzymatic respiration that is accompanied by the formation of free radicals. The process is called photosynthesis.
You cannot do this process without doing your own research and analysis. This is really a very complex study that has a lot to offer
but it’s important. For the sake of clarity, I hope that you will have good access to information, and if you find the explanation of the photosynthetic process useful, feel free to subscribe to my blog about it.
This course focuses on the role both natural selection and genetics play in determining photosynthesis. It is not a simple math question, but I believe there are many variables that affect whether an organism’s photosynthetic system is successful or not. We will use the three main principles to describe each one of these variables. The first principle is called “environmentality”. In the end the choice makes a huge difference.

These conditions are conditions that are either not necessary to maintain the system, or are very difficult or impossible to control. In the case of certain plants, for example, those with photosynthesis, these conditions need to be adjusted by various means. For example one technique known as a red
Section 2:In order to determine if the distance a plant cell is from the light source affects the rate of photosynthesis the students designed an experiment using leaves, a light source, sodium bicarbonate, sodium chloride, tinfoil and a timer. A hole punch was used to create 5 sets of 10 leaf disc, each of which would be placed in a solution. Four solutions were sodium bicarbonate which replaces carbon dioxide in this reaction and provides a medium for the leaf disc to float as photosynthesis occurs and oxygen is produced. One solution was placed 10cm from a lamp used as the light source, one 25cm away, another was wrapped in tin foil and placed 10cm away from the light source, and the fourth was placed behind the lamp in only room light. The fifth set of ten leaf disc were placed into NaCl in order to prove that density was not the reason for floating. In order to reduce error each beaker contained 50mL of its respective solution and distance was measured by two separate students in a straight light from the light bulb in the lamp.
In order to remove any oxygen that had been previously created in the leaves, the disc were placed in a 10cc syringe with liquid soap. Inside the syringe a vacuum was created in order to pull the oxygen gas from the leaves. When all leaves sank in the soap water they were removed and placed in their solutions. In order to prevent false readings any leaves that immediately began floating from left over oxygen were removed from their solutions. All ten disc remained in the NaCL solution and the sodium bicarbonate at 10cm. Four had to be removed from the sodium bicarbonate at 25cm leaving 6 disc. Eight had to be removed from both the room light beaker and the tinfoil wrapped beaker leaving 2 leaf disc in each beaker. The timer was started when the leaves were placed in their separate solutions and were each beaker was agitated every 2min to encourage the disc to float when enough oxygen was present.
Section 3:In this groups NaCl solution 1 of the 10 disc began to float after 18min in the sodium chloride. This was found to be an error as no other group reported a floating disc in their NaCl proving that density of the solution did not cause the disc to float. The error could have
