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.
An Air Conditioning system involves many components such as the Compressor, Condenser, Evaporator and Drier. The A/C compressor is considered the heart of the air conditioning system.It acts as a supplier and regulator of refrigerant.he Freon gas is pumped by the A/C compressor and passed into the condenser. The compressor is one of two junctions in the A/C system which separates the high pressure and the low pressure sides.
