Poaceae have hollow stems called culms plugged at intervals by solid leaf-bearing nodes. Grass leaves are nearly always alternate and distichous (in one plane), and have parallel veins. Each leaf is differentiated into a lower sheath hugging the stem and a blade with entire (i.e., smooth) margins.oaceae have hollow stems called culms plugged at intervals by solid leaf-bearing nodes.

Air conditioning system components consisting of Condensing Unit, Evaporator Coil, Refrigerant line. How air conditioning works is kind of a mystery to many of us. Furnaces are easy to understand, they heat air and blow it around your home in ductwork.
Con: Bacteria, mold and fungus. Air conditioners can be a breeding ground for the growth of bacteria and fungus. Moisture can accumulate in the coils and fan blades from condensation that forms when cold air circulates through the appliance.If left unchecked, things like mold and fungus can build up and get blown out into the air.ir conditioners can be a breeding ground for the growth of bacteria and fungus.
