Biology Coursework Photosynthesis

Without plants, there would be less oxygen molecules present in the atmosphere, creating a potential threat to organisms that require oxygen....[tags: Photosynthesis, Energy, Adenosine triphosphate] - The Process of Photosynthesis Missing Images Plants are one of the many wonders of the world.These organisms take in energy from the sun and water.

This factor will prevent the rate of photosynthesis from rising above a certain level, even if the conditions are improved to meet the best requirements for photosynthesis.

Variables Input - Light intensityis to be varied by increasing and decreasing the distance from the light source to the plant Output - The rate of photosynthesisis to be measured by counting the bubbles of oxygen produced by the plant every two minutes, and therefore finding the rate of photosynthesis Control - The amount of water available to the Elodea will stay the same level in the 400 cm3 beaker.

The chemical equation of photosynthesis is: [IMAGE]6CO2 6H20 C6 H12 O6 6O2 it has been proven many times that plants need light to be able to photosynthesize , so you can say that without light the plant would neither photosynthesize or survive.

The reason light intensity is being used compared to whether or not a plant needs light.

There are many things which can affect the photosynthesis of a plant such as light intensity, temperature and carbon dioxide levels.

There will be a maximum level of photosynthesis during the experiment it is called a limiting factor.

Schwessinger Group - Plants, fungi, evolution, Nicotra Group - Plant physiological ecology, plant evolutionary biology, reproductive ecology, Kruuk Group - Evolutionary ecology and quantitative genetics Use of a tobacco Pathogenesis-related Protein-5 (PR-5) promoter: β glucuronidase (GUS) reporter system to study plant defence activation in response to phytohormones, abiotic stresses and biotic inducers.

An Experiment to Investigate the Effect of Light Intensity on the Rate of Photosynthesis Introduction Photosynthetic takes place in the chloroplasts of green plant cells; it can produce simple sugars using carbon dioxide and water causing the release of sugar and oxygen.

The photosynthetic reactions are divided into two sections: light dependent and light independent reactions.

In this experiment, we will be dealing with the light dependent reactions.
