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.
Nucleus and Mitochondria have DNA. Chloroplasts contain chlorophyll for photosynthesis. Mitochondria is the site of aerobic respiration, and the vacuole gives support to plant cells when filled. Phospholipids make up the cell membrane.
