Photosynthesis is a form of a chemical reaction that transforms energy from the sun in to a chemical energy‚ a carbohydrate known as glucose. Only plants are able to use this process to make their own food. This chemical reaction takes place in Chloroplasts‚ cells that are found in any green part of the plant. Chloroplasts are in green fragments of the plants because it contains a green pigment called chlorophyll. Although Photosynthesis can occur in any green portion of a plant‚ it mostly occurs

rate of photosynthesis increased from a cold temperature to room temperature; however‚ the rate of photosynthesis decreased in the body temperature. This means that the hypothesis was rejected. The rate of photosynthesis did increase‚ but only to a certain point. Based on these results‚ it can be concluded that photosynthesis performs better at room temperature that at cold temperature because thee low temperature slows down the reactions taking place in the chloroplasts. Photosynthesis performs

This means that the light intensity actually has an impact on the plant’s photosynthesis levels. The reason that there are more bubbles in the experiments with more light is because of the oxygen release rate. With more light intensity‚ the rate of photosynthesis happens faster. Since the process of photosynthesis release oxygen‚ the more oxygen will be released creating the bubbles underwater. To clarify‚ photosynthesis is the process of which a plant’s chloroplasts‚ with the aid of the sun (or

Photosynthesis is the process in which autotrophs use light energy to convert carbon dioxide and water into glucose. This conversion into chemical energy is associated with the action of the green pigment chlorophyll. Chlorophyll molecules located in the thylakoid membrane of the chloroplasts are arranged into complexes known as photosystems. Each photosystem contains the reaction center complex and is surrounded by light harvesting complexes. The light harvesting complexes are composed of pigment

affect Photosynthesis? Introduction: Photosynthesis is the process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water. Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a byproduct. It produces sugar and other organic compounds such as lipids and proteins. The sugars are then used to provide energy for the organism. Light reaction is the series of biochemical reactions in photosynthesis that

What Factors Affect the Rate of Photosynthesis in living leaves? Abstract: In this lab‚ four different types of leaves were tested to see the rate at which each leaf photosynthesized. This lab demonstrates how plants store light‚ capture light‚ and use light as energy for reproduction and growth‚ by photosynthesis. The control in this experiment was spinach‚ which was tested before any of the other plants were. The other plants that were tested were English Ivy‚ C4 Plant‚ and a multicolored

The purpose of this lab was to understand that because substances have different properties‚ such as mass‚ that can be separated by chromatography. In our experiment‚ we chose 4 different color source to separate in water. We made sure that all the sources were water soluble because only polar substances will dissolve in water. We chose a black wet-erase marker‚ a red marker‚ a green marker‚ and mixed food coloring to test. The chromatography paper was split into 4 sections‚ about 2 cm above the

Title: Rate of Photosynthesis Introduction: Photosynthesis occurs in plants where the light energy changes to chemical energy. This process occurs in the chloroplast of the plant cell in order to have gas exchange in the organism. Purpose: To measure the effect of light intensity on the rate of photosynthesis in the leaf cells. Hypothesis: The higher the concentration of the sodium bicarbonate solution‚ the faster the leaf of the plant will rise to the surface of the water in the beaker‚ the
