NEET BIOLOGY

Detailed explanation-1: -Since the stomata allows the carbon dioxide to enter and oxygen to exit therefore if there will be sudden increase in carbon dioxide concentration around the leaf will happen then the stomata will get closed so that the excess gas does not enter the cell and this will further decrease the rate of transpiration too.

Detailed explanation-2: -Higher than ambient CO2 concentrations mediate a closure of stomatal pores in plants and conversely, low CO2 concentrations trigger opening of stomatal pores.

Detailed explanation-3: -As the air’s CO2 content rises, many plants reduce their stomatal apertures, because with more CO2 in the air, they don’t need to open their stomates as wide as they do at lower atmospheric CO2 concentrations to allow for sufficient inward diffusion of CO2 for use in photosynthesis.

Detailed explanation-4: -Water stress, high temperatures, and high carbon dioxide concentration causes stomata to close.

Detailed explanation-5: -During those high-carbon-dioxide times, plants that produce fewer stomata will have an advantage and will be common. On the other hand, when carbon dioxide levels are low, plants need many stomata in order to scrape together enough carbon dioxide to survive.
