Chlorophyll

1. Introduction background information. What is the purpose of this experiment? What happens during photosynthesis? What is the role of a photosynthetic pigment? Also, state your hypothesis, independent and dependent variable(s) in this experiment. Photosynthesis is the development of the process which all living plants get their food from the sun, plants absorbed them water from the roots, plants get their food from the sunlight, plants get help of water and carbon dioxide to survive and give…

Light dependent reactions occur in the thylakoid membrane of the chloroplasts and take place only when light is available. During these reactions light energy is converted to chemical energy. Chlorophyll and other pigments absorb energy from sunlight. This energy is transferred to the photosystems responsible for photosynthesis. Water is used to provide electrons and hydrogen ions but also produces oxygen. The electrons and hydrogen ions are used…

Determining the Rate of Photosynthesis and the Effect That pH Has on It Abstract - The purpose of this experiment was to determine what variables affect the rate of photosynthesis. The variable tested was the pH level of the “environment” and this was tested using leaf discs from a plant. By testing the leaf discs in different pH levels of two, four, six, eight, and ten, it was found that the rate of photosynthesis was at its highest in a pH of six. It was also found that the rate of…

the highest potential to drive photosynthesis are blue (490nm) and red (680nm). This is because chlorophyll a absorbs mostly blue light, Some red light is also absorbed. 2) Which wavelengths would you suggest have the poorest potential to drive the photosynthetic light reactions? Explain. Green (500-570nm) has the poorest potential to drive photosynthesis because it is the least absorbed by chlorophyll during photosynthesis. If it has a low absorption rate, then it will also have a low rate of…

light affect the chlorophyll in a plant?” I will also be seeking to answer the question, “Does the color of light affect the size of a tomato?” Another question I want to know the answer to is, “What color of light helps a plant grow the best?” Based on what I know, I expect to see changes in the color of leaves, see different sizes of fruit, and see which color of light helps a plant grow best. I hope to show through my results that the color of light does affect the chlorophyll in a leaf and…

the cell. Photosynthesis happens when water is absorbed by the roots of green plants and is carried to the leaves by the xylem, and carbon dioxide is obtained from air that enters the leaves through the stomata and diffuses to the cells that have chlorophyll. In our experiment we tested how different colored lights would affect how fast the rate of photosynthesis would happen. The rate of photosynthesis is affected by the different wavelengths of light a plant is exposed to because different…

Sea slugs and aquatic plants have similar core features that allow both of them to acquire energy from light, but the sea slugs mechanism is far more involved and revolved around evolution. Elysia chlorotica, or the sea slug, have acquired the ability to conduct photosynthesis in their adult stages of life through their consumption of Vaucheria litorea. Vaucheria litorea are algae that are the primary diet of the developed sea slugs. Juvenile slugs acquire this ability when they ingest the algae…

Lab Question: Does the intensity of light affect the plant’s photosynthesis? Background information: There are three main elements which has a huge impact on the plant’s photosynthesis: light, temperature, and carbon dioxide.(Plant and Light) However, this lab is focused on how the intensity of light affect the plant’s photosynthesis in order to see how the intensity of light affect the plant’s photosynthesis, specifically Elodea plants. Photosynthesis is a process which happens in all plants…

membrane space between them. The stroma in the middle of the chloroplast contain membrane discs known as thylakoids, arranged in interconnected stacks called granum. The membrane of a thylakoid disc contains light-harvesting complexes that include chlorophyll, a pigment that gives plants their green color by reflecting it, while absorbing other colors such as violet and red for energy. There are two stages to photosynthesis,…
