Bookshelf (Page-70) Question 1. Transpiration decreases when water content of the leaves decreases due to insufficient absorption by the root. Such deeply embedded stomata are called sunken stomata. This cookie is set by GDPR Cookie Consent plugin. The high humidity in the air pocket reduces the water potential gradient between the leaf air spaces and the exterior, and therefore decreases the rate of transpiration.

When pines evolved, not only was the Earth becoming drier, but insects were evolving and proliferating. How are evaporation and transpiration similar? Can you find any pores (gaps) in the epidermis? The structure of a hydrophytic leaf differs from a mesophytic leaf due to selective pressures in the environment -- water is plentiful, so the plant is more concerned with staying afloat and preventing herbivory. What is the difference between guttation and transpiration? In leaves with open or partially closed stomata, crypts reduced transpiration by less than 15% compared with nonencrypted, superficially positioned stomata. What is the role of transpiration in plants? Sunken stomata: The term "sunk" refers to something that is hidden. (a) Stomata on the epidermic were blocked; thus no carbon (IV) oxide entered the heat; therefore photosynthesis did not take place; (b) Respiration; Excretion/ transpitation; 4.
