chlorophyll
叶绿素
definition
noun
The green colouring comes from chlorophyll , the same pigment that is found in foliage.
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.
example
Most organisms with 'chlorophyll' have additional pigments to capture more of the light energy that they receive.
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.
Chlorella, a green algae, is rich in essential nutrients including 'chlorophyll' , a useful blood purifier.
The ratio of soluble protein to 'chlorophyll' in the isolated chloroplasts was approximately half that of whole leaf extracts.
In higher plants, the pathways of 'chlorophyll' and haem biosynthesis are tightly regulated at an early step.
The green colouring comes from 'chlorophyll' , the same pigment that is found in foliage.
Greens are full of 'chlorophyll' and one of the best healing foods we can eat raw.
The 'chlorophyll' captures the energy of light, and makes it accessible to the plant for photosynthesis.
Early in the year, when there is plenty of light, the leaves produce 'chlorophyll' , the green colour in grass stains.
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.
Examples of the former are the green 'chlorophyll' pigment in plant leaves and the orange pigment present in carrots, carotene.
Mushrooms do not have 'chlorophyll' and cannot photosynthesize in the way that green plants do, to produce food.
Important in this process are the green 'chlorophyll' pigments in leaves which capture the sun's energy.
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.
Unlike plants, though, cyanobacteria lack a second kind of chlorophyll, known as chlorophyll b, which in concert with 'chlorophyll a' helps plants capture light.
Along the abaxial and adaxial margins of the leaf the subepidermal vascular bundles are interspersed with fibre bundles in the 'chlorophyllous' mesophyll.
In a previous study, we suggested that once Coffea somatic embryos have developed 'chlorophyllous' cotyledons exhibiting active photosynthesis, they could be successfully cultured photoautotrophically.
Various hypotheses have been proposed to explain the reduced viability of 'chlorophyllous' spores, including a higher respiratory rate or inability to recover photosynthetic competence after desiccation.
Their roots cover rock surfaces, are 'chlorophyllous' and have extremely short, leafy and floral shoots scattered on their dorsal surface; they play major roles in adherence, photosynthesis, organogenesis and reproduction.
The efficiency of photosynthesis can readily be assessed by measuring 'chlorophyll a' fluorescence of photosynthetic systems.
The foliose root is 'chlorophyllous' , with extremely reduced vegetative and reproductive adventitious shoots scattered on the dorsal surface, and root hairs (adhesive hairs) on the ventral surface.
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.
They also contain 'chlorophyll a' , the same photosynthetic pigment that plants use.
