THE POMEGRANATE CLASSIFICATION1
Organisms within this domain are eukaryotic; they each have a true nucleus and membrane-bound organelles. The DNA is contained within the nucleus.
Nearly all members of this kingdom are autotrophic and carry out photosynthesis to acquire nutrients. Species within this kingdom exhibit an alternation of generations, meaning their life cycles consist of both multi-cellular haploid and multi-cellular diploid stages.
This phylum (also known as Phylum Anthophyta) consists of flowering plants, called angiosperms. Pollination in these members occurs via wind, water, or animals. The seed is found within a protective covering called fruit.
The diagram below displays the taxonomic breakdown of the pomegranate from the origin of life to the plant group based on morphological characteristics.
Members of this class are commonly referred to as dicotyledons. They have distinct characteristics that set them apart from the monocotyledons, which make up the rest of the Phylum Magnoliophyta. The chart below compares characteristics of monocotyledons and dicotyledons.
The shoots of these plants have phloem within the xylem as well as more than one layer of phloem surrounding the xylem. Phloem and xylem consists of complex tissues in the vascular system of higher plants, and account for woody elements within the fibers (see Glossary).
Members of this family possess simple spiral leaves. They have floral organs that are made up of five to eight petals as well as five to eight sepals. Fruit emerges from the calyx and holds many seeds.
GENUS: PUNICA L.
This is the lone genus within Family Punicaceae. It contains two species” Punica granatum and Punica protopunica.
This diagram displays the taxonomic breakdown of the pomegranate from plant group to species based on morphological characteristics. Punica granatum is a member of the Family Punicaceae, which belows in the Order Myrtales. Another family within this Order, Family Myraceae, contains Eucalyptus dives. This organism is more commonly known as broad-leaf peppermint gum.
SPECIES: PUNICA GRANATUM
Punica granatumliterally translates into “seeded apple”. Commonly known as the pomegranate, this species is a deciduous tree with thorny branches, thick elongated leaves, and hardy fruit that contains many seeds.
This figure is a molecular phylogeny which outlines the evolutionary relationship of Punica granatum with other organisms based on molecular analysis.
