Why are stomata significant to the growth of a plant.

Therefore, as mentioned, stomata play an integral part in water and CO2, entry to the plant, thus having facilitating photosynthesis. Stomata regulate transpiration and CO2 intake by changing its size depending on the environmental signals.

Explanation:

Just as animals breath, plants do so too through the stomata. The gaseous exchange that they are responsible for, facilitate photosynthesis by letting in the essential CO2. Carbon dioxide is used as the fuel to drive photosynthesis, which generates oxygen as a byproduct, which is then released to the atmosphere.
