A. Converting photosynthesis rate from volume of oxygen produced per gram leaf per minute to mol CO2 fixed per area of leaf (in m2) per second. B. Why would one want to express photosynthesis rate as µmol CO2 m-2 s-1? What is the advantage. Answers: A. How to convert photosynthesis rate from volume of oxygen produced per gram leaf per minute to mol CO2 fixed per area of leaf (in m2) per second. Photosynthesis rate can be measured either by seeing how much oxygen is produced by a leaf

respiration. The main role is to transport electrons formed from NADH to oxygen in order to release the energy cells use to make ATP. Photosynthesis: What is the overall goal of photosynthesis? The overall goal of photosynthesis is to convert light energy from the sun into a chemical energy of sugar and other organic molecules. For example‚ apple trees use photosynthesis to produce both oxygen and fruit. Animal life needs oxygen

Introduction Leaves are the most significant photosynthetic tissue for the majority plants and play a crucial role in response to biotic and abiotic disturbances. Leaf shape is seen as one of the most variable and distinct plant traits‚ and variation of leaf morphology can exist among species‚ populations and individuals‚ and within individuals. Because leaves are critical to plant growth and survival‚ it is assumed that the variation in leaf shape represents an adaptive consequence caused by natural

Compare and Contrast Photosynthesis and Cellular Respiration Opposites in photosynthesis and cellular respiration. Is that photosynthesis is taking in carbon dioxide and water by absorbing energy from the sun and then release oxygen and storing glucose. In cellular respiration glucose and oxygen enters and they are converted into carbon dioxide‚ water and ATP energy. But they work alike because they both have electron transport chains and similarly ATP.

Associate Program Material Cell Energy Worksheet Answer the following questions: Cellular respiration: • What is cellular respiration and what are its three stages? A living version of internal combustion-is the main way that chemical energy is harvested from food and converted to ATP energy‚ it is also called an aerobic process‚ which is just another way of saying that it requires oxygen. So cellular respiration is defined as the aerobic harvesting of chemical energy

Chemoheterotrophic organisms obtain energy from the oxidation of organic compounds 7. What is photosynthesis and where does it take place? Photosynthesis is a process used by plants and other autotrophic organisms to convert light energy‚ normally from the sun‚ into chemical energy that can be used to fuel the organisms’ activities. Carbohydrates‚ such as sugars‚ are synthesized from carbon dioxide and water Photosynthesis is the means by which plants harvest light energy to make their own food it takes place

cycles to feed. I explained to him how plants use photosynthesis and respiration to produce sugars for food then releasing the used energy into our atmosphere. Four main factors needed to produce these processes are sunlight‚ oxygen‚ carbon dioxide‚ and water. I would explain to Van Helmont that under a microscope plants have cells that have tiny green pigments that contain chloroplast where all of the chemical reactions are computed. In photosynthesis a plant takes in carbon dioxide‚ water‚ and sunlight

contain chloroplasts‚ which convert the energy in light to chemical energy through photosynthesis. The cylindrical shape of palisade cells allows a large amount of light to be absorbed by the chloroplasts. Beneath the palisade mesophyll are the spongy mesophyll cells‚ irregularly-shaped cells that having many intercellular spaces to allow the passage of gases‚ such as the intake of carbon dioxide for photosynthesis to take place. The stomata is the way in which these gases are exchanged‚ as well as

of an additional phosphate group on the 2’ position of the ribose ring that carries the adenine moiety.In photosynthetic organisms‚ NADPH is produced by ferredoxin-NADP+ reductase in the last step of the electron chain of the light reactions of photosynthesis. It is used as reducing power for the biosynthetic reactions in the Calvin cycle to assimilate carbon dioxide. Synthesis The oxidative phase of the pentose phosphate pathway is a major source of NADPH in cells‚[1] and in cells without mitochondria
