Solar energy conversion in plant leaf stomata as leaf temperature changes

Abstract

The Sun provides energy to the Earth in the form of rays which is used by plants for biomass development. Biomass developed by plants can only release such amount of energy which matches the amount of solar radiation energy absorbed by plants in the biomass production process. The process of CO2 assimilation involves complex biological and physical processes of energy exchange. The article presents information on how the plant uses changing thermal factors and processes in the habitat for intensifying the assimilation process. It analyses the processes of plant energy exchange stimulating the consumption of environmental carbon dioxide and at the same time the increase of biomass and the reduction of environmental air pollution. It has been found that in sunshine a thermal stomata engine (the biological prototype of heat engine) works in a plant leaf and generates mechanical energy at the expense of heat. The article presents the thermodynamic processes and cycle of the plant leaf stomata engine. Mechanical energy developed in a plant leaf is used to intensify the process of assimilation by activating leaf energy and gas exchange with the environment.
