Essay On The Effect Of Light On Photosynthesis

2543 Words11 Pages

Photosynthesis is the process the energy from sun lights to produce ATP which is used to make sugar such as glucose, sucrose, cellulose, and starch. Photosynthesis involves two different processes, which are light dependent reaction and light independent reaction. Light dependent reaction requires light energy to split water molecules (photolysis) into hydrogen ions (H^+), oxygen (O_2) and electrons to make ATP and the light dependent reaction allows plants to grow and make a waste product (oxygen), energy conversion reactions, convert solar energy to chemical energy. In the light independent reaction stage, H^+ and ATP are used to fix 〖CO〗_2 to make organic molecules. Sugar can be produced by the process of Calvin cycle in the chloroplasts …show more content…

For photosynthesis to takes place, there should be a presence of chlorophyll, light, 〖CO〗_2 water and suitable temperature. Temperature, light intensity, and carbon dioxide concentration are possible limiting factors on the rate of photosynthesis. It is because if more than one essential condition for chemical process is favorable, its rate will be limited by the factor which is nearest its minimum value. I am going to observe the effect of using different colors of light on the rate of photosynthesis in the experiment. Since I am interested to grow flowers by myself, I have used to grow variety of flowers and plants. However, I did not know that sunlight and water are essential for plants’ growing. So, the plants just get rotten. Therefore, through this experiment, I am able to find out the effects of colors in photosynthesis. Absorption spectrum is related to my experiment which shows that green color is the poorly absorbed and red and blue color would be absorbed well. Moreover, plants are necessary for us since we inhale oxygen which is produced by plants. It means that producing oxygen by using the process of photosynthesis is important for our body and environment. Therefore, I am willing to see how the use of different colors of lights effect the rate of

Observation In Burns Bog And Watershed Park

783 Words | 4 Pages

In Burns Bog and Watershed Park, the light was blocked at certain times because of the cover of the trees. Light intensity affects the rate of photosynthesis as with more sunlight, more carbon dioxide can be produced for the plants to grow. The types of vegetation is affected by light intensity as when the amount of sunlight decreases, the growth decreases as well. This is why SWMA has more grass plants such as, Aster and Colonial Bent Grass. According to the Spearman's Rank Correlation Coefficient, the correlation coefficient of light intensity and Aster is 0.4.

Nahco3 Lab Report

558 Words | 3 Pages

The null hypothesis, “There is no difference in the concentrations of NaHCO3 and the rate of photosynthetic activity.” is rejected. The alternative hypothesis is supported, that which the greater concentration of NaHCO3, the greater the rate of photosynthesis. Since it was found that the p-value was less than 0.05 in table 1 in all five treatments, this allows the null hypothesis to be rejected. This finding correlates with real life observations of faster rates of oxygen production during lab within the higher concentrations of

Nt1310 Unit 1 Assignment

Background 1. There are and could be numerous reasons that it was done in this manner. I believe one of the reasons was that it could be because the instructor wants the students to be familiar with Ryerson Library Database, which would be highly beneficial for us when it comes to finding other articles, books, or academic material in the future. Another reason could be because it is a legal issue which is explained in the question below. Lastly, it could be because students are relatively lazy, and it would be better if we learn how to use the resources that are given to us, so we wouldn’t have to complain about not being given enough information to do a project or assignment.

Especially since the experiment states that it was a healthy plant, whereas a yellowish, drooping malnourished plant would not be able to provide sufficient data. So for the time being it'll take in CO2 until it stops functioning without the sun. Tube C would also be yellow because there is no longer equilibrium once the plant runs out of initial energy from it's previous lit environment(before being used for the experiment). Tube D will not change because there is nothing with get the blue

Spinach Leaf Photosynthesis

The leaves then make ATP, which reduces NADP to NADPH, and add CO2 into organic molecules. When the leaves go through the process of a light-dependent reaction by being placed in water, oxygen is created through photosynthesis and is released into the interior of the leaf. This causes the leaf to rise. However, since cellular respiration is happening at the same time, the oxygen is also being used up. This means that the leaves must

Biology: Photosynthesis And Respiration

593 Words | 3 Pages

All organisms use food molecules, like glucose to produce ATP. The production of ATP occurs during cellular respiration. ATP provides the cells with energy that is necessary to produce oxygen. The seeds/plants are autotrophic organisms, which produce their food from the energy that the light provides them. To release the stored energy within the food molecules, the germinated seeds carry out respiration and the release of carbon dioxide.

Spinach Leaf Photosynthesis Lab Report

Because carbon dioxide is absorbed by the plant during photosynthesis less carbon dioxide present in the chamber is a sign that photosynthesis is working. The four lights used for this experiment range across the light spectrum on both sides in order to test a wider variety of wavelengths. All lights will be placed directly on the spinach leaf at the same distance so as not to give any spinach leaf a different light intensity, which could affect the data. This experiment will be able to show which light, ranging across the light spectrum, will allow the Spinach to perform photosynthesis more efficiently.

Compare And Contrast Cellular Respiration And Photosynthesis

420 Words | 2 Pages

photosynthesis and cellular respiration are extremely important in the cycle of energy to sustain life simply because nutrients would not metabolize in a productive manner. Both have numerous stages in which the process of energy occurs, and relationships with organelles located in the eukaryotic cell. Photosynthesis is a process by which green plant and other organism manufacture their food using sunlight to synthesize foods from carbon dioxide and water while cellular respiration is the oxidation of organic compounds that occurs within cells, producing energy for cellular processes. Photosynthesis occurs within organelles called chloroplasts. These organelles can absorb light, and are located inside of leaves.

Germinated Peas Inspire Synthesis

412 Words | 2 Pages

The purpose of this lab was to measure the amount of CO2 gas given off by germinated peas under certain conditions of light. We conjectured that the more amount of light the peas are exposed to, the higher the respiration rate they will have. Our data supported this because it showed that the germinated peas that were exposed to light 24 hours before the experiment had a steeper slope (as seen in table 1), therefore having a greater respiration rate. The peas that were not exposed to any light 24 hours before the experiment had a reduced rate because of its lack of exposure to light. Both pea’s respiration rates showed that the more light the peas were exposed to, the greater respiration rate they would have (Figure 1).

Introduction Plants are a major necessity in the balance of nature, people’s lives, and our terrain. We may not realize it, but plants are the ultimate source of food for almost 95% of the world population so says the National Group of Food. It’s a fact that over 7,000 species of plants are being consumed today. Plants are one of the reasons that we get clean water; as they help regulate the water cycle.
