The linear mass density can then be understood as the derivative of the mass function with respect to the one dimension of the rod (the position along its length =) The SI unit of linear mass density is the kilogram per meter (kg/m). Linear density of fibers and yarns can be measured by many methods.
An Arabidopsis thaliana chlorophyll(ide) a oxygenase gene (cao), which is responsible for chlorophyll b synthesis from chlorophyll a, was introduced and expressed in a photosystem I-less strain of the cyanobacterium Synechocystis sp.
Chlorophyll absorbs all colors except for green (green is reflected and therefore visible). Also, chlorophyll in photosystem II, or p680 absorbs predominantly red light, andâ¦ chlorophyll in photosystem I, known as p700 absorbs blue light the best. But as stated above, both reflect green light giving photosynthetic plants their green color. 10 people found this useful. SSKhalsa.
