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

that help it carry out basic functions that are necessary to maintain life and proper photosynthesis. The first and outermost layer of tissue is called the dermal layer. This is the plant’s ‘skin’ and serves the plant mainly as a source of protection. Also present in the dermal layer of the leaves are stomata‚ which are tiny openings that allow carbon dioxide to enter and complete the Calvin Cycle of photosynthesis. The innermost layer of the plant is called the vascular tissue and is composed of phloem

The symbiotic relationship between plants and people is made possible by the differences between cellular respiration and photosynthesis. While cellular respiration occurs in all living organisms‚ photosynthesis relies on chlorophyll and is unique to plants‚ algae‚ and some bacteria. Respiration and photosynthesis are essentially the same process in reverse. During photosynthesis CO2 and H2O are converted to glucose and oxygen‚ while cellular respiration uses glucose and oxygen which are converted

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

loops affect them? •Explain the first and second laws of thermodynamics. •Ecologists say there is no “away” to throw things to‚ and that everything in the universe tends to slow down and fall apart. 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

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
