Definition of photosynthesis in US English:

photosynthesis

noun

  • The process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water. Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a byproduct.

    • ‘Stomata are involved in two of the most important plant processes, photosynthesis and transpiration.’
    • ‘These populations do not have the ability to utilize exogenous bicarbonate for the process of photosynthesis.’
    • ‘When maize encounters water deficits, there is a decline in photosynthesis per plant.’
    • ‘Drought reduces productivity by inhibiting plant growth and photosynthesis.’
    • ‘This is an integrative trait, reflecting both light and dark reactions of photosynthesis.’
    • ‘Many forms are capable of photosynthesis and hence resemble plants in the way that they obtain energy.’
    • ‘As injury progresses, heavily damaged leaves lose their green colour and photosynthesis is much reduced.’
    • ‘Carbohydrate depletion and reduced photosynthesis are the main effects of submergence on plant tissues.’
    • ‘Normally the proportion of the two isotopes of carbon is simply controlled by the rate of photosynthesis in plant tissues.’
    • ‘To avoid the production of oxygen via photosynthesis, plants were kept in the dark.’
    • ‘Anthocyanins are water soluble pigments but are not involved in photosynthesis.’
    • ‘These results are consistent with the previous report that water stress inhibits photosynthesis.’
    • ‘Evidence is increasing of a new player in carbon metabolite regulation of photosynthesis.’
    • ‘Light is necessary for photosynthesis in plants, but the supply of light in natural environments is not constant.’
    • ‘It is created, as we have seen, during photosynthesis, when organisms strip oxygen from water molecules.’
    • ‘It has long been known that magnesium availability to plants imposes limits on photosynthesis.’
    • ‘Carbohydrates accumulate in plants during the autumn as rates of photosynthesis begin to exceed growth.’
    • ‘Their job is to absorb the rays from the sun to begin the process known as photosynthesis.’
    • ‘Possible use of serine derived directly from photosynthesis was ignored in this analysis.’
    • ‘In addition, rates of light-limited photosynthesis and oxygen yield are decreased in the mutants.’
