Photosynthesis 1. Would you illuminate your house plants with a green light bulb? Why or why not? It would not be a wise choice to put a plant under a green light bulb. The reason for this is that due to the fact that the leaves are green they reflect green light. This shining green light onto the flowers will cause photosynthesis to stop. Since the light is being reflectd‚ the cells do not get any light. With out light they cannot carry out the everyday occurrence of photosyntesis. If the

pigments of spinach leaves can be separated. The knowledge gained in this experiment is relevant to understanding how the process of photosynthesis works. A Real-world application for this includes the harvesting of clean energy sources‚ as scientific advances have led the way to artificial photosynthesis on the path to replace fossil fuels (Nath‚ 237). Photosynthesis converts light received from the sun into chemical energy known as ATP. Visible light is absorbed by the pigments found in plants. Carbon

#2 Elodea and Photosynthesis by __________________ Name:_____________________ Class:_____________________ Teacher:_____________________ Date:_____________________ Elodea and Photosynthesis Introduction: Photosynthetic organisms (cyanobacteria) first evolved about 3.5 billion years ago and are the oldest know fossils on Earth. Cyanobacteria live in water‚ can manufacture their own food‚ and are one of the most important groups of bacteria on Earth. The Cyanobacteria have been important

McGowan Goldfish Respiration Lab Introduction The purpose of this experiment was to recognize the effects of temperature on the breathing rate of goldfish (Carassius auratus). Goldfish obtain oxygen from the water; the fish have to distribute the oxygen from the water into their bloodstream. This transfer of oxygen occurs over a surface area of capillary membranes contained in the feathery filaments of the gills located beneath the operculum. According to “The Respiration System of a Goldfish”

Cellular metabolism encompasses the many processes that work together to keep the cells in dynamic equilibrium. Cellular metabolism is responsible for providing energy to the cell and is an essential element of life. There are several complex‚ involved processes involved in cellular metabolism including glycolysis‚ Krebs’s cycle‚ and electron transport. Metabolism itself can be broken down into two different categories: catabolic and anabolic. Catabolic metabolism involves the breakdown of large

Through this experiment‚ Egeria densa was observed using a microscope. The task was to observe and identify the different types of cell‚ cytoplasmic streaming‚ and plasmolysis of Egeria densa. First‚ the microscope was examined and investigated to master the use of the equipment. A microscope slide grid which was on the slide glass was required to be seen clearly using 4x‚ 10x and 30x. During the latter part of the experiment‚ the Egeria densa was observed using the microscope to understand the

Investigation of the rate of photosynthesis of pondweed. Research question: How does the concentration of sodium bicarbonate relate to the amount of oxygen produced by Elodea (Canadian pond weed) in the process of photosynthesis? Hypothesis: If there is an increase in concentration of sodium bicarbonate the amount of oxygen produced will increase because the sodium bicarbonate concentration will increase the carbon dioxide levels. Independent variable- Concentrations of sodium bicarbonate (8%

The drug “dinitrophenol” (DNP) was prescribed by some physicians in the 1940’s to help patients lose weight. This unsafe method was abandoned after a few patients died. DNP uncouples the chemiosmotic machinery by making the lipid bilayer of the inner mitochondrial membrane leaky to H+. Explain how this could cause weight loss. In chemiosmosis‚ NADH are passed along the electron transport chain‚ with energy used to pump protons across the inner mitochondrial membrane. As the protons are transferred
