Class: Environmental systems and societies Teacher: David. A Student name: Krutarth Mehta Date: 13/3 Relevant to: 2.5.2. Describe photosynthesis in terms of inputs‚ outputs and energy transformations. Criteria to be assessed: PL‚ DCP‚ DEC. Background: Photosynthesis is the reaction carried out by green plants to produce a supply of food. The reactions occur in the chloroplasts and require light energy. 6CO2 + 6H2O C6H12O6 + 6O2 In aquatic plants

INTRODUCTION The purpose of this mathematical report is to investigate a tree’s ability to capture sunlight in relation to possible correlations between the tree’s growing capacity and leaf length. A variety of mathematic techniques will be used to examine how a tree’s height relates to the length of its leaves. This data will then be used to analyse the tree’s ability to efficiently capture sunlight and move liquid around the tree. It is predicted that this report will prove that as a tree’s growing

Death is something that is inevitable‚ It’s not something humans and life in general can’t run away from. It is especially something soldiers cannot walk away from. In “The Things They Carried”‚ Tim O’Brien’s characters suffer this reality time and time again in the Vietnam War. A war that costed the life of thousands of American servicemen. Men who suffered horrific conditions and watched their close friends die in devastating combat and treacherous terrain. It could be easy to call the men who

SOLAR POWER IN TODAYS WORLD JEROME T. GARDNER COLUMBIA SOUTHERN UNIVERSITY ABSTRACT Since first discovered in the 1860s‚ the concept of storing energy from the sun to use as a source of power has been studied and pursued by many programs. Either using solar collectors or photovoltaic cells‚ the methods of using solar power are becoming more efficient and cost-effective. Solar technology is currently being used by homes and businesses‚ but is still too expensive and risky for many residents. Researchers

Plan I plan to investigate how light intensity affects the rate of photosynthesis in pondweed. The rate of photosynthesis will be measured by the number of bubbles given off (considering that oxygen is produced as a waste gas during photosynthesis). The light intensity is measured by the distance between the lamp and pondweed. Fair test: Fix: the amount of pondweed‚ the amount of water and sodium hydrogen carbonate solution in the test tube‚ the time allowed for each experiment Change: the

Toxicology Lab 1. In this investigation‚ a wide range of concentrations of Sodium Chloride (NaCl) solution were created and the effects that they had on radish seeds were tested. This ultimately created a doseresponse experiment in which it was detectable whether or not radish seeds were a reliable bioassay for the toxicity of NaCl. The goal of this experiment was to determine a correlation between toxicity and seed germination/radicle

LED (light emitting diode) lights are programmed to deliver the wavelengths of light that plants prefer to create optimum growing conditions Plants would grow along the building’s south-facing sides to get maximum sunlight exposure. Solar panels that surround the building also provide extra power. Wind turbines which are installed at the top of the building will generate electricity to help power equipment.

with dark hair all over to protect ourselves from too much sunlight. However‚ as the human evolved and lost a significant amount body hair‚ the skin‚ the largest organ of the body‚ would become exposed to the strong ultraviolet rays of the sun. Ultraviolet B‚ a specific type of ultraviolet light‚ is beneficial as it effectively converts our cholesterol into Vitamin D‚ which the body cannot simply live without. However‚ too much sunlight exposure and harmful effects quickly outnumber the beneficial

where energy from sunlight is captures in Photosystem 2 and then 1‚ the electrons generated in Photosystem 1 then moves along the electron transport chain. The moving of electrons causes a hydrogen ion gradient that is used in the final step to produce ATP‚ by the ATP Synthase. The equation for this reaction is 6CO2 + 6H2O C6H12O6+6O2 or‚ carbon dioxide +water sugars + oxygen . This reaction takes place on the thylakoid membrane of the chloroplast and uses energy from sunlight to produce compounds
