Photosynthesis Abstract: An experiment was carried out to determine how certain factors such as light intensity and availability of carbon dioxide‚ affected the rate of photosynthesis. The rate of photosynthesis was measure by the amount of oxygen produce (cm3/min). A valid conclusion was made and most of the results were in accordance with the prediction‚ although there were some anomalies present. The errors and limitations were evaluated and some improvements were suggested. Introduction: Photosynthesis

Chloroplasts and Photosynthesis All animals and most microorganisms rely on the continual uptake of large amounts of organic compounds from their environment. These compounds are used to provide both the carbon skeletons for biosynthesis and the metabolic energy that drives cellular processes. It is believed that the first organisms on the primitive Earth had access to an abundance of the organic compounds produced by geochemical processes‚ but that most of these original compounds were used up billions

Environmental Impacts on Ecosystems Introduction An ecosystem is a community of living organisms (plants‚ animals and microbes) in conjunction with the nonliving components of their environment (things like air‚ water and mineral soil)‚ interacting as a system. These biotic and abiotic components are regarded as linked together through nutrient cycles and energy flows. Ecosystems are controlled both by external and internal factors. Once outside factors affect these systems

Ecosystem is a community of living organisms (plants‚ animals and microbes) in conjunction with the nonliving components of their environment (things like air‚ water and mineral soil)‚ interacting as a system. These components are regarded as linked together through nutrient cycles and energy flows. As ecosystems are defined by the network of interactions among organisms‚ and between organisms and their environment‚ they can come in any size but usually encompass specific‚ limited spaces (although

A wetland is a land area that is saturated with water‚ either permanently or seasonally‚ such that it takes on the characteristics of a distinct ecosystem.[2] Primarily‚ the factor that distinguishes wetlands from other land forms or water bodies is the characteristic vegetation that is adapted to its unique soil conditions. Wetlands consist primarily of hydric soil‚ which supports aquatic plants.[3][4] The water found in wetlands can be saltwater‚ freshwater‚ or brackish.[4] Main wetland types

are at low concentrations‚ photosynthesis may be inhibited‚ thus restricting phytoplankton growth. Levels above 175 mg CaCO3/L reduces natural food production in ponds which‚ in turn‚ leads to a decrease in optimal production. Salt water is slightly alkaline and has a strong buffering capacity so alkalinity is not usually of concern for most seawater and brackish water aquaculturists. 2. Biochemical oxygen demand ( and COD) It is a measure of the amount of oxygen required by bacteria‚ algae

Well‚ here’s on creative and pretty cool way to recycle old lighters by transforming them into mini motorcycles. The things you will need are two empty lighters‚ if there not empty go out side to do the first part. A pair of sharp scissors‚ a small screw driver‚ nimble fingers‚ and pliers. When making

Background Theory Photosynthesis: Plants require water from the soil‚ sunlight and carbon dioxide found in the atmosphere for growth and development. In the process of photosynthesis‚ carbon dioxide and water – in the presence of chlorophyll and light energy – are converted into sugar and oxygen‚ which is given off as a by-product. Generally‚ as sunlight increases in intensity‚ the rate of photosynthesis also increases [1]. This means greater food production within the plant. Many garden vegetables
