Why is the light energy required to open the stomata lower than the light energy required for photosynthesis?

Hi Orooba,

Thank you for asking

Look, we will discuss this in different events.

Studies on guard cell shows that the red light induces accumulation of sucrose that causes osmoregulation.
Blue light plays important role in stomatal movement by changing in the osmoregulation (Causing K⁺ion to move inside guard cell).

Where as high intensity of light (Combination of Blue and red light) is required to cause the effective photosynthesis.

Hope the answer of the question

You should know that sunlight comes to plants as a major source of energy given by sun.The energy from the light of the sun enters the pores of the stomata of the leaves of the plants and energy is consumed within the processes performed by plant and is stored in the mitochondria of the cell of the plant cell.Thus, one can say that for photosynthesis to occur,sunlight is essential.
