Photosynthesis Green plants absorb light energy using chlorophyll in their leaves. They use it to react carbon dioxide with water to make a sugar called glucose. The glucose is used in respiration, or converted into starch and stored. Oxygen is produced as a by-product. This process is called photosynthesis. Temperature, carbon dioxide concentration and light intensity are factors that can limit the rate of photosynthesis. Photosynthesis summary Photosynthesis [photosynthesis: The chemical change...

Photosynthesis Notes

process of photosynthesis requires sunlight for its nutrients to make their way into the chlorophyll on green plants. This suggests that without direct sunlight, photosynthesis will not be completed correctly or the plants functions will not work properly. Majority of plants that undergo photosynthesis have chlorophyll stored within them, it is what gives them their green color. However, there are few species of plants that don’t acquire chlorophyll, but still undergo the process of photosynthesis. Specific...

Photosynthesis Lab

An Experiment to Test the Effect of Temperature on the Rate of Photosynthesis in Green Algae Background Photosynthesis is an amazing process where plants are able to create their own food as well as oxygen using sunlight, carbon dioxide (co2), and water. The part of the plant responsible for photosynthesis is the enzymes in the chlorophyll (structures that carry out photosynthesis located in leaves). Photosynthesis is the process of creating glucose. Water + Carbon Dioxide + Sunlight = Glucose...

Respiration and Photosynthesis

“Respiration” and “Photosynthesis” All life depends on two chemical reactions “Respiration” and “Photosynthesis”. These two processes are quite crucial because they are a source to nearly all life on Earth. Both of these processes are quite similar yet differentiate vastly. In this essay I’ll be comparing and contrasting “Photosynthesis” and “Respiration”. I’ll start by discussing what actually happens...

Photosynthesis Paper

The effect of different wavelengths of light on photosynthesis rate in spinach leaves Abstract: This experiment was performed to test the effect of different wavelengths of light had on photosynthesis. According to the results gathered we can say that if two plants are put under different lights, one green and one a normal light, that the plant under the normal light will perform photosynthesis at a higher rate than the plant under the green light. This experiment is important because it shows...

Investigation 5: Photosynthesis Problem: If the leaf disks are treated in a way you know increases the net rate of photosynthesis, should they start to float faster or slower? Why? Hypothesis: If the leaf disks were bathed in a red light source, then the rate of photosynthesis would increase than leaf disks that are bathed in a regular light source because chlorophyll absorbs red pigment and reflects green pigments. Therefore, shining a red light source onto the leaf disks would cause them...

Chlorophyll and Photosynthesis

Photosynthesis Matt Lazar 5/13/96 8th Hr. When you and me eat, we find our food. When plants eat, they make their own food and energy. They make their food and energy through a process called photosynthesis. Through photosynthesis oxygen is also produced. Photosynthesis is "a process in which green plants synthesize carbohydrates from carbon dioxide and water....The reverse of this reaction provides energy for plants, for animals that eat plants, for animals that eat animals that eat plants"...

Photosynthesis Theory

Background Theory Photosynthesis: Plants require water from the soil, sunlight and carbon dioxide found in the atmosphere for growth and development. In the process of photosynthesis, carbon dioxide and water – in the presence of chlorophyll and light energy – are converted into sugar and oxygen, which is given off as a by-product. Generally, as sunlight increases in intensity, the rate of photosynthesis also increases [1]. This means greater food production within the plant. Many garden vegetables...
