Sentences with phrase «chlorophyll levels»
Chlorophyll levels refer to the amount of a green pigment called chlorophyll found in plants. It helps plants capture sunlight for photosynthesis, which is how they make their own food. High chlorophyll levels indicate healthy and thriving plants, while lower levels may suggest issues with plant growth or health. Full definition

Those blooms (one example from January 2013 shown, with chlorophyll levels depicted in shades of yellow and red; gray masses are clouds) can last up to a month after an iceberg passes, the team notes.
If a plant treated with a potential drug exhibits low chlorophyll levels and fast stem growth, the compound might also inhibit glutamate overstimulation in the brain, she says.
«I liked how they combined traditional oceanographic measurements like chlorophyll levels and primary production, and recent satellite work by other groups that looked at glacial melt,» said Scott Doney, a scientist at the Woods Hole Oceanographic Institution.
High chlorophyll levels indicate a fall bloom; the lack of meso - zooplankton in the area of the krill aggregation is likely due to krill grazing.
