These kinds of observations led Priestley to offer an interesting hypothesis that plants restore to the air whatever breathing animals and burning candles remove.

The process takes place in the leaves of green plants, this is what the leaves are for.

An absorption spectrum is a graph showing the percentage of light absorbed by pigments within the chloroplast, for each wavelength of light. An example is the absorption spectrum of chlorophyll a and b. The best absorption is seen with violet-blue light. There is also good absorption with red-orange light. However most of the green-yellow light is reflected and therefore not absorbed. This wavelength of light shows the least absorption.

What is the function of a chloroplast? | Yahoo Answers

Theory: Before I predict what will happen I must look at how photosynthesis occurs.

The light-independant reactions of photosynthesis occur in the stroma of the chloroplast and involve the conversion of carbon dioxide and other compounds into glucose. The light-independent reactions can be split into three stages, these are carbon fixation, the reduction reactions and finally the regeneration of ribulose bisphosphate. Collectively these stages are known as the Calvin Cycle.

During carbon fixation, carbon dioxide in the stroma (which enters the chloroplast by diffusion) reacts with a five-carbon sugar called ribulose bisphosphate (RuBP) to form a six-carbon compound. This reaction is catalysed by an enzyme called ribulose bisphosphate carboxylase (large amounts present within the stroma), otherwise known as rubisco. As soon as the six-carbon compound is formed, it splits to form two molecules of glycerate 3-phosphate. Glycerate 3-phosphate is then used in the reduction reactions.

Reaction: photosynthesis of Canadian pondweed (Elodea) Introduction- what is photosynthesis.

Pathogens: An organism that causes disease. Photosynthesis: The process by which plants and some other organisms capture the energy in sunlight and use it to make food. Prokaryote: A cell without a nucleus Protein: Large organic molecule made of carbon, hydrogen, oxygen, nitrogen, and sometimes sulfur.

Non-Communicable: A type of disease that cannot be spread from a person who is sick to other people. : The nucleus controls all the cell's activity, its like the brain of the cell. Objective: a lens or system of lenses in a microscope, telescope, etc., that forms an image of an object.

Introduction Photosynthesis occurs only in the presence of light, and takes place in the chloroplasts of green plant cells....

Animals that consume plants also make use of this energy, as do those that consume those that consume plants, and so on to the top of the food chain.

As important a job as making all of the world's food is, there's another vital function that photosynthesis performs: It generates the oxygen that oxygen-breathing animals need to survive.

What is the difference between Chlorophyll and Chloroplast

Photosynthesis occurs inside chloroplasts. Chloroplasts contain chlorophyll, a green pigment found inside the thylakoid membranes. These chlorophyll molecules are arranged in groups called photosystems. There are two types of photosystems, Photosystem II and Photosystem I. When a chlorophyll molecule absorbs light, the energy from this light raises an electron within the chlorophyll molecule to a higher energy state. The chlorophyll molecule is then said to be photoactivated. Excited electron anywhere within the photosystem are then passed on from one chlorophyll molecule to the next until they reach a special chlorophyll molecule at the reaction centre of the photosystem. This special chlorophyll molecule then passes on the excited electron to a chain of electron carriers.

Variables: The variables that might affect the rate of photosynthesis in this experiment are: Temperature: When the temperature rises so does the rate of photosynthesis; this is because as the temperature around the plant rises the enzymes controlling photosynthesis inside the chloroplasts heat up and start moving around faster, the fast moving molecules collide with other fast moving enzymes causing them to react....
