techniques. In plants‚ the paraquat acts in the presence of light (). This is because as the engergy of light is absrobed by chlorophyll (which is in the chloroplast) it is then moved via a flow of electrons through photosystem I (produces free electrons to drive photosynthesis) (). Paraquat is known to divert this flow‚ putting a halt to photosynthesis‚ as the paraquat ion reacts with the free electrons from photosynthsis I‚ to create the paraquat which is now in an oxidized form (paraquat radical formed)

January 31‚ 2014 Mr. Robinson IB Biology I 2ND Period The Effects of Light on Plant Growth Introduction: Photosynthesis is the process in which plants use light energy‚ water‚ and carbon dioxide to produce food. Plants use the food they make for the growth and for the carrying out other life processes. Sunlight is the natural energy source for photosynthesis. White light form the sun is a mixture of all the colors of the light spectrum: red‚ orange‚ yellow‚ green‚ blue‚ and violet. Light

called photosynthesis. This process assists in nourishing plants and keeping them alive. For example‚ trees grow very tall in the rainforest where there is an abundance of water in order to reach as much light as they can. For this reason‚ in order to survive the chloroplast in plants must capture light energy from the sun and convert it into chemical energy that is stored in sugar and other organic molecules (Photosynthesis‚ 2014‚ p. 185). In plants that contain chlorophyll‚ the photosynthesis process

Below are a list of concepts and ideas you need to know for the first Bio 100/107 Test Chapter 1: What is the organizational hierarchy? What is each level? What are emergent properties? At what level does life emerge? Organisms interact with the environment: energy and atoms Unity explains that cells have several common features. What are those features? What is diversity? How does Evolution mediated by Natural Selection explain Unity and Diversity? Chapter 2: Life is composed of atoms

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

Within the thylakoid membranes of the chloroplast‚ are two photosystems. Photosystem I optimally absorbs photons of a wavelength of 700 nm. Photosystem II optimally absorbs photons of a wavelength of 680 nm. The numbers indicate the order in which the photosystems were discovered‚ not the order of electron transfer. Under normal conditions electrons flow from PSII through cytochrome bf (a membrane bound protein analogous to Complex III of the mitochondrial electron transport chain) to PSI. Photosystem

4. Describe how prokaryotes carry out photosynthesis and cellular respiration when they lack compartmentalized organelles such as chloroplasts and mitochondria. The area of cellular respiration in prokaryotes is the respiratory membrane. For aerobic prokaryote the infoldings of the plasma membrane are similar to the cristae of mitochondria‚ whose purpose in eukaryotic cells is cellular respiration. In photosynthetic prokaryotes‚ the area responsible for cellular respiration is the thylakoid membrane
