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.
Rating Newest Oldest. Best Answer: The mesophyll is the leaf tissue where most of the chloroplasts are found and photosynthesis takes place. The mesophyll is differentiated into the palaside mesophyll and teh spongy mesophyll.The palaside mesophyll is made up of one or more layers of narrow, elongated parenchyma cells; these cells have a higher concentration of chloroplasts, and therefore these are the cells in which most of the photosynthesis takes place.hotosynthesis takes place in chloroplasts...which contain chlorophyll pigment,which is necessary for photosynthesis.misophyll cells of the leaf contain maximum number of chloroplasts...it is the main site of photosynthesis.
