Meaning of chlorophyll in English:



mass noun
  • A green pigment, present in all green plants and in cyanobacteria, which is responsible for the absorption of light to provide energy for photosynthesis.

    ‘The green colouring comes from chlorophyll, the same pigment that is found in foliage.’
    • ‘Unlike plants, though, cyanobacteria lack a second kind of chlorophyll, known as chlorophyll b, which in concert with chlorophyll a helps plants capture light.’
    • ‘Examples of the former are the green chlorophyll pigment in plant leaves and the orange pigment present in carrots, carotene.’
    • ‘They also contain chlorophyll a, the same photosynthetic pigment that plants use.’
    • ‘Mushrooms do not have chlorophyll and cannot photosynthesize in the way that green plants do, to produce food.’
    • ‘Early in the year, when there is plenty of light, the leaves produce chlorophyll, the green colour in grass stains.’
    • ‘Important in this process are the green chlorophyll pigments in leaves which capture the sun's energy.’
    • ‘In leaf tissue, the first outwardly visible signs of senescence are declining rates of photosynthesis and loss of chlorophyll.’
    • ‘The green comes from chlorophyll, which allows the microscopic plants to get energy from the sun.’
    • ‘Most organisms with chlorophyll have additional pigments to capture more of the light energy that they receive.’
    • ‘The chlorophyll captures the energy of light, and makes it accessible to the plant for photosynthesis.’
    • ‘The chloroplast structure and the pigment assortment that includes chlorophyll a and c2, but not c1, suggest that only the red algae may be more primitive.’
    • ‘The efficiency of photosynthesis can readily be assessed by measuring chlorophyll a fluorescence of photosynthetic systems.’
    • ‘The ratio of soluble protein to chlorophyll in the isolated chloroplasts was approximately half that of whole leaf extracts.’
    • ‘Chlorella, a green algae, is rich in essential nutrients including chlorophyll, a useful blood purifier.’
    • ‘In higher plants, the pathways of chlorophyll and haem biosynthesis are tightly regulated at an early step.’
    • ‘It is chlorophyll, specifically a kind called chlorophyll a, which transfers the energy absorbed from light to the molecules which go about storing it chemically.’
    • ‘When the potato is green, chlorophyll and solanine levels dramatically increase.’
    • ‘However, some genepy has a greenish tint depending on the amount of chlorophyll in the plants.’
    • ‘Greens are full of chlorophyll and one of the best healing foods we can eat raw.’
