Thus, most plants can only use ~10% of full mid-day sunlight intensity. [6] This dramatically reduces average achieved photosynthetic efficiency in fields compared to peak laboratory results. However, real plants (as opposed to laboratory test samples) have many redundant, randomly oriented leaves.
The scientific use of life-form schemes emphasizes plant function in the ecosystem and that the same function or "adaptedness" to the environment may be achieved in a number of ways, i.e. plant species that are closely related phylogenetically may have widely different life-form, for example Adoxa moschatellina and Sambucus nigra are from the ...
Diprobase is a British brand of the American pharmaceutical company Schering-Plough. Its trademark stems from the now older range of corticosteroids the company still manufactures; Diprosone and Diprosalic. The Dipro being suggestive of betamethasone dipropionate. Diprobase was originally conceived from the emollient vehicle these products had ...
Hypersensitive response (HR) is a mechanism used by plants to prevent the spread of infection by microbial pathogens.HR is characterized by the rapid death of cells in the local region surrounding an infection and it serves to restrict the growth and spread of pathogens to other parts of the plant.
The Private Life of Plants is a BBC nature documentary series written and presented by David Attenborough, first shown in the United Kingdom from 11 January 1995.. A study of the growth, movement, reproduction and survival of plants, it was the second of Attenborough's specialised surveys following his major trilogy that began with Life on Earth.
The pineapple is an example of a CAM plant.. Crassulacean acid metabolism, also known as CAM photosynthesis, is a carbon fixation pathway that evolved in some plants as an adaptation to arid conditions [1] that allows a plant to photosynthesize during the day, but only exchange gases at night.
Another example of a CAM plant is the pineapple. The C 4 construction is most famously used by a subset of grasses, while CAM is employed by many succulents and cacti . The trait appears to have emerged during the Oligocene , around 25 to 32 million years ago ; [ 36 ] however, they did not become ecologically significant until the Miocene , 6 ...
Diaphoretickes (/ ˌ d aɪ. ə f ə ˈ r ɛ t ɪ k iː z / DY-ə-fə-RET-i-keez) is a major group of eukaryotic organisms, with over 400,000 species. The majority of the earth's biomass that carries out photosynthesis belongs to Diaphoretickes. [1]
