Introduction: Photosynthesis is the process by which green plants use the light energy to convert carbon dioxide and water into simple sugar called glucose‚ which provides a basic energy source for the plant. Photosynthesis occurs in leaves that contain specialized cell structures called chloroplasts. Chloroplasts contain molecules of a green pigment called chlorophyll‚ consisting largely of carbon and hydrogen. It gives green color and absorbs the necessary light for photosynthesis. Chloroplasts

High-fat Diet Contributes to Aggressive Behavior Hypothesis: High-fat diet contributes to aggressive behavior. Introduction: Aggression is a behavior that is destructive‚ hostile or violent and is intended cause harm‚ injury or damaged to the target person or object. Aggression and violence are the major problems in our society and one of the main contributions of this behavior is socioeconomic status (SES). According to the American Psychological association (APA)‚ socioeconomic status is

Photosynthesis: Plant cells vs. Solar Cells Chevon Allen 01/23/2010 SCI-115 Professor Garcia Photosynthesis and the semiconductor-based solar cell are very similar process with different ways of reaching the same goal. In photosynthesis‚ plant cells harness the solar energy of the sun with carbon dioxide to transform water molecules into hydrogen‚ oxygen‚ and electrons. Just like photosynthesis‚ Semi conductor based solar cells harness the solar energy of the sun for the same purposes

Effects of Photosynthesis of Spinach Leaves in Different Light Conditions Introduction Photosynthesis is the process of converting solar energy‚ carbon dioxide (CO2)‚ and water (H2O) into carbohydrates (CH2O) and oxygen (O2). Sometimes the end product of photosynthesis is glucose (C6H12O6). Photosynthesis takes place in the chloroplasts of plant cells. Here membranous thylakoids are stacked in grana surrounded by the stroma. During the light reactions‚ pigments within the thylakoid membranes

respiration and photosynthesis are almost exact opposites. Photosynthesis is anabolic; it builds up glucose‚ or sugar‚ from light energy‚ water and carbon dioxide. The chemical equation for photosynthesis is: 6CO2 + 6H2O + Light Energy C6H12O6 + 6O2. Cellular respiration‚ on the other hand‚ is catabolic. It breaks down glucose to form carbon dioxide and water. The chemical equation for cellular respiration is: C6H12O6 + 6O2 6CO2 + 6H2O + 38 ATP. Cellular respiration and photosynthesis follow the

intensity on the rate of photosynthesis. What is Photosynthesis? Photosynthesis is how plants get their food. The reason why plants have leaves‚ roots or being green is all linked to photosynthesis. In photosynthesis‚ a plant takes carbon dioxide from the air and water from the soil and uses the light from sunlight to turn them into food. Photosynthesis occurs only in the presence of light‚ and takes place in the chloroplasts of green plant cells. Photosynthesis can be defined as the production

Introduction: Trying to find a good‚ quantitative procedure that students can use for exploring photosynthesis is a challenge. The standard procedures such as counting oxygen bubbles generated by an elodea stem tend to not be “student” proof or reliable. This is a particular problem if your laboratory instruction emphasizes student-generated questions. Over the years‚ I have found the floating leaf disk assay technique to be reliable and understandable to students. Once the students are familiar

Cells of all organisms are capable in acquiring the energy necessary to fuel chemical reactions for growth‚ repair‚ survival‚ and reproduction. Photosynthesis & cellular respiration are the main pathways of energy flow in living things. Photosynthesis is a process by which plants and some other organisms convert‚ light energy from the sun‚ CO2 from the air & H2O from the earth‚ into chemical energy stored in molecules like glucose. Cellular respiration is a process in which O2 is delivered to cells
