Factors That Affect Photosynthesis - YouTube

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.

The effect of many of these factors is difficult to determine quantitatively because they interact, they also affect other processes in the plant. For example, the importance of water to photosynthesis cannot be demonstrated easily. Simply depriving a plant of water kills it, but the cause of death may not be connected with photosynthesis. The importance of water can be demonstrated using water labeled with a heavy isotope of oxygen, 18O, and tracing the isotope using an instrument called a mass spectrometer which can measure the masses of atoms. One batch of (green algae) is placed in water in which the oxygen atoms have been replaced by the heavy isotope. Then a second batch of in unlabelled water is given a supply of carbon dioxide labeled with 18O. Only the first batch of gives off oxygen labeled with 18O, confirming that the oxygen formed in photosynthesis comes only from water, not from carbon dioxide.

Photosynthesis is affected by many factors, both external (in the environmental) and internal (inside the plant). External factors include light intensity, the wavelength of light, carbon dioxide levels, temperature, wind velocity, and water and mineral supplies. Internal factors include type and concentration of photosynthetic pigments, enzyme and water content, and leaf structure, and position.

What are the Factors that affect Photosynthesis

The collected data can be analysed to find the mean, median and mode values of organisms in a particular area.The physical factors that may affect organisms include:(Note that these do not include factors such as the presence or absence of predators.)So, for example, daisy plants need light energy from the sun to make their own food using photosynthesis.

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...
