Siberian tiger / Amur tiger (Panthera tigris altaica) Siberian tiger / Amur tiger â interesting facts. The Siberian tiger is the largest living representative of felids, and one of the largest felids that have ever lived. It is usually taller than the Bengal tiger by 5-10 cm (2-4 in).
Three factors can limit the speed of photosynthesis - light intensity, carbon dioxide concentration and temperature. Without enough light, a plant cannot photosynthesise very quickly, even if there is plenty of water and carbon dioxide. Increasing the light intensity will boost the speed of photosynthesis.
Gradually the rate falls of and at a certain light intensity the rate of photosynthesis stay constant (from point B to C on the graph). Here 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.Many plants spread out their leaves in such a way that each leaf maximises the amount of light falling on them and the lower leaves are not shaded by the ones above.radually the rate falls of and at a certain light intensity the rate of photosynthesis stay constant (from point B to C on the graph).
