Green photosynthetic matter of plants – chlorophyll is found in the chloroplasts of a cell and is necessary to photosynthesis. In cannabis cultivation, chlorophyll gives buds a harsh taste and smell. After harvest, it is recommended to properly cure your cannabis flower. The chlorophyll, which will cause dried cannabis to smell like grass or hay, is consumed by bacteria during the curing process.
Chlorophyll is any of several related green pigments found in cyanobacteria and in the chloroplasts of algae and plants. Its name is derived from the Greek words χλωρός (khloros, "pale green") and φύλλον (phyllon, "leaf"). Chlorophyll allows plants to absorb energy from light. Those pigments are involved in oxygenic photosynthesis, as opposed to bacteriochlorophylls, related molecules found only in bacteria and involved in anoxygenic photosynthesis.
Chlorophylls absorb light most strongly in the blue portion of the electromagnetic spectrum as well as the red portion. Conversely, it is a poor absorber of green and near-green portions of the spectrum. Hence chlorophyll-containing tissues appear green because green light, diffusively reflected by structures like cell walls, is less absorbed. Two types of chlorophyll exist in the photosystems of green plants: chlorophyll a and b.
