What is the significance of water stress in stomatal density?

Solution

stomaata is tiny pore present on leaf surface is used for gas exchange . it is also use ful in transpiration . wter vapour goes to atmosphear through these pores is the process of transpiration ..

Number and distribution of stomata is related to water avilability . Mostly in dicot plant stomata present lower side of leaf and in monocot stomata present on both side but in aqatic plant stomata is upper part of leaf . to reduce water los desert plats have stomata in deep pit of fleshy leaves and leaves have been reduced in cactus to avoid transpiration .

experiment show the relationshpip of stomatal density with regard to water status . modret water density had possitive effect on stomatal number but less water density reduces the number of stomata . the stomatal size decreases with water defifict .
