In tropical rain forests, the canopy is thick and shorter plants growing below it, receive filtered light How are they able to carry out photosynthesis ?

Solution

We know that light is rarely a limiting factor for photosynthesis because just 10% of the full sunlight is sufficient to ensure light saturation. In plants which grow under thick canopy in forests; less amount of light may slow down the rate of photosynthesis but it cannot stop photosynthesis during daytime. Hence, these plants are able to carry on photosynthesis.
