Without enough light, a plant cannot photosynthesize very quickly - even if there is plenty of water and carbon dioxide and a suitable temperature. Increasing the light intensity increases the rate of photosynthesis, until some other factor - a limiting factor - becomes in short supply.
they are caused by mutation. the best example of it are human blood groups.
