Reduce - to buy less and use less. Incorporates common sense ideas like turning off the lights, rain barrels, and taking shorter showers, but also plays a part in composting/grasscycling (transportation energy is reduced), low-flow toilets, and programmable thermostats.
Reuse - elements of the discarded item are used again. Initiatives include hand-me-downs, garage sales, quilting, travel mugs, and composting (nutrients).
Recycle - discards are separated into materials that may be incorporated into new products. This is different from Reuse in that energy is used to change the physical properties of the material. Initiatives include Composting, Beverage Container Deposits and buying products with a high content of post-consumer material. Within recycling there is distinction between two types:
Upcycle- converting low-value materials in high-value products (more desirable) Downcycle - converting valuable products into low-value raw materials (less desirable)
Because of the proximity of mesosomes to the cell wall septal region, they may be the sites of some of the wall membrane synthetic processes.
It has been suggested that mesosome formation may preced and coordinate the formation of the septum.
They act as an anchor to bind and pull apart daughter chromosomes during cell division.
