Plants classification

Plants can be divided into eleven divisions, according to basic factors such as methods of reproduction, energy sources, and physical structure (see Table 4.1). The division is a modification of the Linnaean classification system, being between kingdom and phylum. 

Division Common name Approximate number of species Characteristics 

Bryophyta Bryophytes, liverworts, hornworts, mosses 31,600 No specialized vascular tissues and no real roots must absorb moisture from their aboveground environment. 

Psilophyta Whisk ferns 5 Vascular plants with no seeds

Because of the complexity of integrated processes and the large volume of available data in highly automated plants, classification algorithms are increasingly used nowadays. They are applied to the design of monitoring systems and to reduce the dimension of the data reconciliation problem. 

The decision regarding blast resistant requirements is made by the owner, typically through standard practice or by following a site specific methodology as described in CCPS Building Guidelines or API RP-752. Both decision mechanisms may employ a plant classification or categorization approach based on the severity of blast hazards.
