Question

Write the observation how the plant regulate the amount of light water an carbon dioxide

Answer 1

Controlling indoor air movement provides the greenhouse plants with a constant supply of carbon dioxide. Strategically placed horizontal fans throughout a greenhouse allow air to press closer to the foliage for peak photosynthesis action. The concentrated carbon dioxide results in larger leaves, stronger plant stems and possible early flowering and fruiting. However, air movement must be coupled with proper ventilation. Closing off the greenhouse to outside air circulation lowers indoor carbon dioxide levels because the plants use the gas quickly while transferring oxygen to the air in exchange.
