How Does Too Much Light Affect The Rate Of Photosynthesis

Decent Essays

There are three main factors that affect the rate of photosynthesis; temperature, carbon dioxide concentration and light intensity. Specifically, in order for a plant to photosynthesise at a sufficient rate, there must be enough light as a plant is unable to do this process if there is an inadequate amount. The more photons of light that hit the leaves results in a greater amount of chlorophyll molecules that are ionised and more ATP is produced. Therefore, by increasing the amount of light the plant is receiving there will be a greater amount of energy resulting in a faster rate of photosynthesis. However, if there is an insufficient amount of supply from other factors, then when there is too much light it can affect the rate of photosynthesis.
