#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

chemical bonds of ATP and carbohydrates‚ a process called photosynthesis (Knox et al.‚ 2005). However‚ this report is only concerned with photosynthetic pigments and what wavelength of light they absorb‚ rather than the process of photosynthesis itself. Chlorophyll is a green‚ light absorbing pigment found in plants which allow them to utilise the energy in light to survive. This is because chlorophyll is the main pigment associated with photosynthesis. Chlorophyll a is the main type of light absorbing

Partner: Oleg and Joseph Biology (D) Ms. Wainman The relationship between Photosynthesis and cellular respiration Introduction: Photosynthesis is the process which used by plants to capture light energy and use it to do chemical reactions that change carbon dioxide and water into oxygen and energy (ATP)‚ carbohydrates just like sugar. Cellular respiration is the process that releases energy by breaking down glucose and other food with oxygen. Plants cells do photosynthesis and cellular respiration

Photosynthesis vs. Semiconductor based solar cell. Photosynthesis vs. Semiconductor based solar cell. Wais Ghowsi Instructor: Meri Stanec SCI 115 April 24th‚ 2011 What is Photosynthesis? Photosynthesis simply means the conversion of light energy into chemical energy by living organisms. In photosynthesis‚ the raw materials are water and carbon dioxide. Energy is taken from sunlight and the end products give out glucose and oxygen. It is the most important‚ naturally occurring process

respiration and photosynthesis. Photosynthesis is performed by plant organisms and some bacteria‚ and cellular respiration is performed by all living organisms. These two processes are reliant on each other. Photosynthesis creates oxygen‚ which is used in cellular respiration. Cellular respiration in turn creates carbon dioxide‚ which is an important “ingredient” in the process of photosynthesis. Let’s take a closer look at what makes these processes so important to all living things. Photosynthesis is the

The majority of the experimentation in this project relied on the idea that there is a relationship between concentration and absorbance of a solution. This is easy to understand if you can visualize the particles in the solution; and this is especially true if the particles in solution portray a distinct color. The more particles there are in the solution‚ the more they will obstruct the path of the light. This occurs the most at the analytical wavelength‚ where the most light is absorbed by

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%

purpose of this lab was to investigate whether veins affect photosynthesis rate. It was predicted that having veins would decrease the rate because chloroplast might be less frequent due to the vascular tissue. For this experiment‚ 4 groups were set up: veins and no veins in CO2 solution‚ and veins and no veins in distilled water‚ the distilled water groups served as controls. These 4 groups were placed under a light bulb in order for photosynthesis to occur. No disks experience movement in the first 7
