Which Joe gave his name to ‘sloppy joes’? We look at five interesting sandwiches and their lexical origins.
A green pigment, present in all green plants and in cyanobacteria, responsible for the absorption of light to provide energy for photosynthesis. Its molecule contains a magnesium atom held in a porphyrin ring.
- ‘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.’
- ‘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 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.’
- ‘They also contain chlorophyll a, the same photosynthetic pigment that plants use.’
- ‘The green comes from chlorophyll, which allows the microscopic plants to get energy from the sun.’
- ‘Examples of the former are the green chlorophyll pigment in plant leaves and the orange pigment present in carrots, carotene.’
- ‘In leaf tissue, the first outwardly visible signs of senescence are declining rates of photosynthesis and loss of chlorophyll.’
- ‘However, some genepy has a greenish tint depending on the amount of chlorophyll in the plants.’
- ‘The green colouring comes from chlorophyll, the same pigment that is found in foliage.’
- ‘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.’
- ‘Greens are full of chlorophyll and one of the best healing foods we can eat raw.’
- ‘Most organisms with chlorophyll have additional pigments to capture more of the light energy that they receive.’
- ‘Mushrooms do not have chlorophyll and cannot photosynthesize in the way that green plants do, to produce food.’
- ‘Unlike plants, though, cyanobacteria lack a second kind of chlorophyll, known as chlorophyll b, which in concert with chlorophyll a helps plants capture light.’
- ‘The chlorophyll captures the energy of light, and makes it accessible to the plant for photosynthesis.’
- ‘The efficiency of photosynthesis can readily be assessed by measuring chlorophyll a fluorescence of photosynthetic systems.’
Early 19th century: coined in French from Greek khlōros green + phullon leaf.
