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.
two photosystems are called photosystem I* and photosystem II*. Both photosystems absorb energy from sunlight. Photosystem II and Electron Transport In photosystem II, several things happen. â¢ Chlorophyll and other light-absorbing molecules absorb energy from sunlight. The energy is transferred to electrons (eâ) that leave the chlorophyll. These high-energy electrons enter the electron transport chain, which is made of proteins in the thylakoid membrane. â¢ Water molecules are split apart into oxygen, hydrogen ions, and
