five separate, oval petals 8-12 mm (5/16-1/2 in) long. The reddish-purple plums are fleshy, oval, 2.0-2.7 cm. (0.75-1.25 in) long; each fruit contains one seed. Wild plum flowers are insect pollinated.
In the physical sciences, an intensive property (also called a bulk property), is a physical property of a system that is not depending on the system size or the amount of mat â¦ erial in the system: it is scale invariant.
By contrast, an extensive property of a system is directly proportional to the system size or the amount of material in the system (see examples below). For example, density is an intensive quantity (it does not depend on the quantity), while mass and volume are extensive quantities.
