The rate of photosynthesis may vary with changes that occur in environmental temperature‚ wavelength of light‚ and light intensity. Using a photosynthetic organism of your choice‚ choose only ONE of the three variables (temperature‚ wavelength of light‚ or light intensity) and for this variable. • Design a scientific experiment to determine the effect of the variable on the rate of photosynthesis for the organism • Explain how you would measure the rate of photosynthesis in your experiment

energy by converting carbon dioxide and water into glucose and oxygen‚ known as a process called photosynthesis. By adding hydrogen ions to carbon dioxide C-H bonds are made that hold energy which is released in mitochondrion‚ an organelle. This process of the release of energy is known as respiration. Without respiration‚ photosynthesis would not be able to perform. The process of photosynthesis is able to perform its duties with the help of an organelle called chloroplast as well. Within the

What do they mean? •Explain the processes of photosynthesis and respiration. •What qualities make water so unique and essential for life as we know it? •Why are big‚ fierce animals rare? •How and why do elements such as carbon‚ nitrogen‚ phosphate‚ and sulfur cycle through ecosystems? 2-2 © 2014 by McGraw-Hill

Nutrition in Plants – Mineral Nutrition- essential minerals for plant growth MODULE - 2 Forms and Function of Plants and Animals 9 Notes NUTRITION IN PLANTS – MINERAL NUTRITION Sometimes you may observe that a potted plant kept in sunlight and provided with sufficient water does not grow. Its leaves look pale and weak. Plant may not even flower properly. Such a situation is an indication‚ that the plant may not be getting all that is required for normal growth and development. In most of such

Determining Rates of Photosynthesis Through Chloroplasts Introduction: 1)Background= 2) Purpose= measure the rate of photosynthesis in chloroplasts. 3) The chloroplast will be subjected to two experimental conditions- light‚ and the absence of light‚ using a spectrophotometer to determine the amount of DPIP reduced at specific time intervals under each condition. 4) I predict the amount of DPIP reduced will vary for each condition and increase over the time intervals. I hypothesize

Today photosynthesis is widely known across the globe‚ and with all of its reactions. It is often broken into two steps: the “light” reactions and the “dark” reactions. Both of these reactions are fundamental to the process of photosynthesis‚ and photosynthesis is vital for plants to survive. Because plants are the main energy source for organisms on Earth‚ and without them‚ we could not survive‚ photosynthesis is extremely important in the study of life‚ biology. Without Melvin Calvin‚ however‚

to the 5 carbon sugar rubisco bisphosphate‚ instead of carbon dioxide as in the process of photosynthesis. It is the alternate pathway used by the enzyme. This enzyme being both a carboxylase and an oxygenase does not have the capability to differentiate between the carbon dioxide molecule or the oxygen molecule as a result of which it can assist in both the reaction of photorespiration and photosynthesis‚ even though they are the opposite pathways. In general RubisCO favours carbon dioxide to oxygen
