Rate of photosynthesis
Gradually the rate falls and at a certain light intensity, the rate of photosynthesis remain constant (from point B to point C on the graph). Hence, a rise in light intensity has no affect on the rate of photosynthesis as the other factors such as temperature and carbon dioxide become limiting. Photosynthesis is a chemical reaction that is fundamental to life. In this video we are going to have a look at the factors that affect the rate of photosynthesis. There are 3 main factors: light As the rate of photosynthesis increases and it reaches a plateau, the lights intensity or CO2 concentration increases. When it comes below a certain temperature, the rate of photosynthesis For example, light intensity can only increase the rate of photosynthesis up to the point that temperature or carbon dioxide levels limit it. Similarly, even if you have plenty of carbon dioxide

The process of photosynthesis is commonly written as: 6CO 2 + 6H 2 O → C 6 H 12 O 6 + 6O 2. This means that the reactants, six carbon dioxide molecules and six water molecules, are converted by light energy captured by chlorophyll (implied by the arrow) into a sugar molecule and six oxygen molecules, the products. Photosynthesis involves the same molecules and chemical reactions in land plants and aquatic plants. Floating plants photosynthesize much like plants that grow on land. However, the process presents more of a challenge for aquatic plants if they are fully submerged below the surface of the water. What are the Effects of Light Intensity on the Rate of Photosynthesis and Oxygen Production in Plants. Science project. What are the Effects of Light Intensity on the Rate of Photosynthesis and Oxygen Production in Plants. This science fair project idea focuses on the production of oxygen by plants during the photosynthesis process. A common experiment when studying plant biology is investigating factors affecting the rate of photosynthesis. Plants produce oxygen which is invisible and odorless, so the experiment is usually carried out with water plants; the bubbles of oxygen produced are observed. Investigating the rate of photosynthesis. This is an example of a common experiment used to investigate light intensity and the rate of photosynthesis. This should help you understand how to work Rate of photosynthesis and light intensity, rate of photosynthesis and % level of CO2, rate of photosynthesis and temperature. Graph (not enough light slows down the rate of photosynthesis) Light provides the energy needed for photosynthesis, so as the light level is raised, the rate of photosynthesis increases streadily to a certain point The rate of photosynthesis depends on the concentration of enzymes and chlorophyll. (ii) Emerson (1927): He found a direct relationship between the amount of food formed and the chlorophyll content. 8. PROTOPLASMIC FACTOR. Photosynthesis does not start immediately after the appearance of chlorophyll in very young leaves. It starts after some time.
The rate of photosynthesis is a gross measure of the rate at which a plant captures radiant energy and fixes it in organic carbon compounds. However, it is often more important to consider, and very much easier to measure, the net gain.

The main factors affecting rate of photosynthesis are light intensity, carbon dioxide concentration and temperature. In any given situation any one of these may

3 Nov 2014 In photosynthesis, the energy from the sun is used to turn carbon dioxide (CO2) and water into sugar. Oxygen is a waste product. More light can
As with any other enzyme-controlled reaction, the rate of photosynthesis is affected by temperature. At low temperatures, the rate of photosynthesis is limited by the number of molecular collisions The process of photosynthesis is commonly written as: 6CO 2 + 6H 2 O → C 6 H 12 O 6 + 6O 2. This means that the reactants, six carbon dioxide molecules and six water molecules, are converted by light energy captured by chlorophyll (implied by the arrow) into a sugar molecule and six oxygen molecules, the products.

A brief outline of various ways to measure the rate of photosynthesis - including measuring photosynthesis via the uptake of carbon dioxide (e.g. using immobilised algae), via the production of oxygen in pondweed, via the increase in dry mass, and via the production of carbohydrates. At temperatures above 68 degrees Fahrenheit, or 20 degrees Celsius, the rate of photosynthesis decreases because the enzymes do not work as efficiently at this temperature. This is despite the increase of carbon dioxide diffusion into leaves.
