Photosynthesis Lab Report

Have you ever really wondered how different variables can affect how plants go through photosynthesis? Well, in this experiment, the purpose was to see how various environmental conditions can affect the overall photosynthetic capacity of a specific plant. The factors, light, darkness, cold, and heat were applied to see how the different components would affect the photosynthesis on spinach plants. Each group was given a different factor to test. Out group was given the light factor. The hypothesis for this experiment is that when adding light as a factor, the light will affect the overall plant photosynthesis.

Photosynthesis occurs each time the sun’s light reaches the lives of a plant. The chemical ingrediants for photosynthesis are carbon dioxide (CO2), a gas that passes from the air into a plant via tiny pores, and water (H20), which absorbed from the soil by the plant’s roots. Inside leaf cells, tiny structures called chloroplasts use light energy to rearrange the atoms of the ingrediants to produce sugars, most importantly glucose (C6H12O6) and other organic molecules. Chlorophyll gives the plant its green color (Simon, 02/2012, pp. 92-93). Chemical reactions transfers the sun’s light energy into the chemical bonds that hold energy-carrying molecules. The most common are

Photosynthesis is the conversion of light energy to chemical energy into sugars. It is the process in plants that uses carbon dioxide, water, and sunlight from its surroundings and releases oxygen as a byproduct (6H2O+6CO2+light energy -> C6H12O6+6O2). Photosynthesis is required for plants because they are autotrophs, organisms that make their own food. Plants require a specific environment that is ideal to them to be able to carry out the process. Environmental conditions can either increase or decrease the rate of photosynthesis. Things like colors of light, pH, and temperature can all affect the rate of photosynthesis in plants.

Photosynthesis is the process in which plants consumed inorganic materials like solar light, carbon dioxide and water and converted it to an organic molecule like sugar and an inorganic gas like oxygen. Light is one of the major elements influencing the rate of photosynthesis; direct light concentration affects the noncyclic pathway (light

Photosynthesis is a process used by plants and other organisms to convert light energy into chemical energy that can later be released to fuel the organisms ' activities. Plants need photosynthesis to survive. The balanced chemical equation for photosynthesis is 6 CO2 + 6 H2O ? C6H12O6 + 6 O2. In English terms, this equation translates to six carbon dioxide plus six

An important part of photosynthesis is the intake of carbon; thus, it can be presumed that increasing the amount of available carbon will increase photosynthetic activity. In most plants there is an increased rate of photosynthetic rate, but it is limited by other factors and reaches a plateau (Lei H, Zhishan Z.

15) Obtain the boiled chloroplast suspension, mix, and transfer 3 drops to cuvette 4. Immediately cover and mix cuvette 4. Insert it into the spectrophotometer's sample holder, read the percentage transmittance, and record it in Table 4.4. Replace cuvette 4 into the incubation test tube rack. Take and record additional readings at 5, 10, and 15 minutes. Mix the cuvette's contents just prior to each readings. Remember to use cuvtte 1 occasionally to check and adjust the spectrophotometer to 100% transmittance.

“Photosynthesis is a biochemical process for building carbohydrates using energy from sunlight and carbon dioxide taken from the air”, (Morris, J. (2016) Biology How Life Works. New York, NY.). It is a system that uses plants and specific algae to synthesize molecules from both water and carbon dioxide. The oxygen we breathe and the food we eat is fueled by photosynthesis because it is an energy source. Photosynthesis occurs in eukaryotic and prokaryotic organisms and some examples are humans, trees, and plants. Biological systems use photosynthesis as an energy source. Where there is a source of sunlight, there is a chance

During this experiment the scientist tested this question “What combination of light intensity, light color, and CO2 level would produce the highest amount of photosynthesis?” The scientist believed the highest amount of CO2 level and light level along with each using white light would produce the highest amount of photosynthesis possible. The amount of oxygen bubbles we got ranged from 4 to 28. However when we put the results from each test together, we only got 26 bubbles. The scientist believes with more testing of each combination, we could find a better ratio. The data unfortunately did not support the scientist’s hypothesis.

Photosynthesis is a vital process that autotrophs use to transfer light energy into chemical energy. Photosynthesis ultimately produces O2 and glucose. It, like many other biological processes, can be affected by environmental variables. The variable that we altered in the following experiment are intensity, light wavelengths, and pigment types. In order to do this, we conducted three experiments. In the first experiment, we examined the effect of light intensity by placing vials with chloroplasts with DPIP at different light distances in which the results varied. Initially, 30cm away was the most effective for photosynthesis. Then 24cm appeared to be the most effective. Followed by 49cm at minutes 25 and 30. In the second experiment, we

Photosynthesis is a huge concept to learn and understand in the field of biology. Plants have their own special way of using the ATP they produce. Photosynthesis is a process where plants harness the sunlight they receive and they produce carbohydrates, as well as oxygen for living things and other plants. Now the sunlight ultimately powers the process of

     Photosynthesis is a reproductive system that occurs in plants. The main components required for photosynthesizing are sunlight, energy, water and mineral from soil, and carbon dioxide from the air. Once these components are combined they

     Photosynthesis is a biochemical process in which plant, algae, and some bacteria harness the energy of light to produce food. Nearly all living things depend on energy produced from photosynthesis for their nourishment, making it vital to life on Earth. It is also responsible for producing the oxygen that makes up a large portion of the Earth¡¦s atmosphere. Factors that affect photosynthesis are light intensity and wave length, carbon dioxide concentration, and temperature.
