use a process called photosynthesis to covert energy from the sun into energy they can use for their activities. The plant’s chloroplasts‚ along with water‚ carbon dioxide‚ and light are the essential elements required for photosynthesis to take place. The “photo” part of photosynthesis is in reference to the fact that the process requires light. The simplest form of the photosynthesis equation is: H2O + CO2 ----light----> (CH2O)N + O2 As shown in the equation‚ photosynthesis produces carbohydrates

germination of a seed affected by sunlight?” Experimental Hypothesis: We believe these results will occur. 1. The seeds that are water deprived (1 mL of H2O a day) will not grow very well due to a lack of water which is important in photosynthesis and also lacks nutrients. The seeds may also die off due to a lack of water. 2. The seeds that are have a proper amount of water (10 mL of H2O a day) will grow the best and achieve the greatest height‚ and overall best appearance.

Chlorophyll Extraction This easy science project shows simple and efficient method of chlorophyll extraction from a plant. This is only a demonstration of working method which can be refined and used for a full scale science project. Plants contain many pigments in different proportions. For flowering plants it’s mostly a combination of chlorophyll-A‚ chlorophyll-B‚ pheophytin and Carotenes. These pigments have shades of green‚ blue green‚ grayish‚ and yellow-orange. Their concentration is

Photosynthesis Experiment Introduction Photosynthesis is a process used by plants‚ making inorganic molecules into organic molecules (food) using sunlight. Carbon dioxide + Water (mainly from rain) Glucose + Oxygen From this process‚ carbon dioxide comes from environment. Glucose‚ as a product is used to make energy for growth. Lastly‚ the oxygen is a waste product in this chemical reaction‚ which become part of the Earth’s atmosphere. At this experiment‚ carbon dioxide and water

Write the overall equation for photosynthesis in both symbols and words. 4. Photosystems I and II are both located in the thylakoid membrane. What advantage does their proximity provide? 5. What does the Calvin cycle do? 6. What is the difference between an autotroph and a heterotroph? Give an example of each type of organism. 7. Explain how heterotrophs

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

AP Lab #5 Plant Pigments/Photosynthesis I. Identifying the Effects of Different Variables of Light and Carbon Dioxide on the Rate of Photosynthesis and Observing the Separation of Pigments Through Chromatography II. Introduction Plants have a variety of pigments‚ all of which absorb a different color of light. The three main pigments are chlorophyll a‚ chlorophyll b and carotenoids. Chlorophyll a is the primary plant pigment that absorbs red and blue light‚ which ultimately appears green to the human eye

product of photosynthesis‚ which is the process that converts energy in sunlight to chemical forms of energy that can be used by biological systems2. Many organisms are not able to use the energy obtained from sunlight directly; however‚ plants are able to use this energy and convert it into chemical energy by converting CO2 (carbon dioxide) and H2O (water) to organic materials3. The energy source for photosynthesis comes from sunlight‚ which allows for the fuel that drives photosynthesis. This process

first ensure that the ecosystem’s foundation is remaining strong‚ a foundation known as photosynthesis. When photosynthesis is functioning as it should‚ in its fullest capacity‚ all organisms benefit from it in some way. Furthermore‚ scientists aim to better understand the photosynthetic process to help enhance the efficiency and quality of life on Earth. By fully understanding the function of photosynthesis‚ some environmental adjustments can then be made to refine the photosynthetic process. In
