Problem: Why do leaves change color in the fall? Background: Leaves contain many pigments such as chlorophyll b‚ xanthophyll‚ and beta carotene besides chlorophyll a. They are part of the photosystem in the thylakoids. Pigment molecules can be separated by a procedure called chromatography. The procedure uses a special paper and solvent. The chlorophyll molecules adhere to the paper. The solvent molecules move up the paper by capillary action. Each chlorophyll molecule will travel up the paper at

our experiment) light as it physical alters temperature which directly affects photosynthesis‚ respiration‚ transpiration - loss of water and absorption of water and nutrients. The rate of these processes increases with an increase in temperature responses is different with different crops. The extent of growth and yield responses of plants to elevated CO2 depends on the photosynthetic pathway. Crops with C3 photosynthesis will respond markedly to increasing CO2 concentrations. Common C3 crops are

Introduction: The rate of photosynthesis varies greatly with changes in wavelengths of light. Light’s colour is determined by its wavelength of light‚ and thus it is possible to devise an experiment to determine which wavelengths of light are most productive for photosynthesis than others. In this experiment I use a plant called Elodea (pond weed). Elodea is native to North America and it is also widely used as aquarium vegetation. The basic structure of these plants are whirls of leaves around

Per glucose‚ the Krebs Cycle produces 6 CO2 (discarded as waste in animal cells‚ recaptured for photosynthesis in plant cells). C.

Carbon dioxide is both a vital requirement for producers – the first organisms in any food chain‚ and at times a dangerous waste product. Where plants use carbon dioxide during the Calvin cycle of photosynthesis‚ at night they also produce small quantities due to respiration. Fundamentally‚ carbon dioxide reacts with ribulose bisphosphate to produce glycerate 3-phosphate in the light independent reaction. In turn glycerate3-phosphate is reduced to triose phosphate using reduced NADP
