Addition Polymers. Addition polymers such as polyethylene, polypropylene, poly(vinyl chloride), and polystyrene are linear or branched polymers with little or no cross-linking. As a result, they are thermoplastic materials, which flow easily when heated and can be molded into a variety of shapes.
According to what I have read a stalk of celery is the whole bunch....a rib, is one of the many that make up the stalk....so many of the recipes are really wrong when th â¦ ey say one stalk....you would have way too much celery.
Celery, Apium graveolens, is a dicot. It is in the parsley family (Apiaceae or Umbeliferae), along with other notable dicots like the carrot.t has several characteristic fea â¦ tures of a dicot, including vascular bundles in a ring around the center of the stem, or pith, flower parts in 5's, a prominent taproot, and leaves with a branching network of veins. Celery is commonly mislabeled as a monocot, though the reason for the misunderstanding is unclear.
