This process is also affected by the temperature surrounding the plant (the species of plant we experimented with, pond weed, photosynthesised best at around 20 degrees centigrade.) Light, temperature & CO2 are known as limiting factors, and each is as important as the next in photosynthes...
Light is a very important factor in the rate of photosynthesis, in my project I am going to test that plants do need light in order to photosynthesise.
It will be very interesting to see how light will influence the rate of photosynthesis in plants and what will happen if they do not get the required light in order to produce starch .
Light - a form of radiant energy, absorbed by the pigments found in the leaves of plants
The rate of photosynthesis at most ordinary land plants increases when the temperature rises up to about 25 degrees Celsius
Prediction: I predict that the oxygen bubbles will decrease when the lamp is further away from the measuring cylinder, because light intensity is a factor of photosynthesis.
Tie is working to define and understand the ad/abaxial regulatory network in Arabidopsis. He has identified transcription factors that act downstream of the HD-ZIPIII and KANADI master regulators. These "middlemen" transcription factors appear to control subprograms of ad/abaxial development. Tie is especially interested in those that are responsible for establishing the shoot apical meristem at the apical pole of the embryo. His work has also shed light on factors downstream of both drought signaling and the ad/abaxial regulatory network. These factors are potential players in a novel ABA signaling pathway used in vegetative tissues.
Farmers can use their knowledge of these limiting factors to increase crop growth in greenhouses. They may use artificial light so that photosynthesis can continue beyond daylight hours, or in a higher-than-normal light intensity. The use of paraffin lamps inside a greenhouse increases the rate of photosynthesis because the burning paraffin produces carbon dioxide, and heat too.
Three factors can limit the speed of photosynthesis: light intensity, carbon dioxide concentration and temperature.
