Transpirational cooling is the cooling provided as plants transpire water. Excess heat generated from solar radiation is damaging to plant cells and thermal injury occurs during drought or when there is rapid transpiration which produces wilting. [1] Green vegetation contributes to moderating climate by being cooler than adjacent bare earth or ...
Chlorophyll is any of several related green pigments found in cyanobacteria and in the chloroplasts of algae and plants. [ 2 ] Its name is derived from the Greek words χλωρός, khloros ("pale green") and φύλλον, phyllon ("leaf"). [ 3 ] Chlorophyll allows plants to absorb energy from light.
1) An increased rate of evaporation due to a temperature rise will hasten the loss of water. 2) Decreased relativehumidity outside the leaf will increase the water potential gradient. Relative humidity. Drier surroundings give a steeper water potential gradient, and so increase the rate of transpiration. Wind.
Zygomycota. Zygomycota, or zygote fungi, is a former division or phylum of the kingdom Fungi. The members are now part of two phyla: the Mucoromycota and Zoopagomycota. [ 1] Approximately 1060 species are known. [ 2] They are mostly terrestrial in habitat, living in soil or on decaying plant or animal material.
The basic function of the xylem is to transport water from roots to stems and leaves, but it also transports nutrients. [ 1][ 2] The word xylem is derived from the Ancient Greek word ξύλον ( xylon ), meaning "wood"; the best-known xylem tissue is wood, though it is found throughout a plant. [ 3]
Guard cells are cells surrounding each stoma. They help to regulate the rate of transpiration by opening and closing the stomata. Light is the main trigger for the opening or closing. Each guard cell has a relatively thick and thinner cuticle on the pore-side and a thin one opposite it. As water enters the cell, the thin side bulges outward ...
Scanning thermal microscopy ( SThM) is a type of scanning probe microscopy that maps the local temperature and thermal conductivity of an interface. The probe in a scanning thermal microscope is sensitive to local temperatures – providing a nano-scale thermometer. Thermal measurements at the nanometer scale are of both scientific and ...
The International Code of Nomenclature for Cultivated Plants ( ICNCP) is a guide to the rules and regulations for naming cultigens, plants whose origin or selection is primarily due to intentional human activity. [ 1] It is also known as Cultivated Plant Code. Cultigens under the purview of the ICNCP include cultivars, Groups ( cultivar groups ...
