Species: Ananas comosus

Lets Take a Closer Look:

Domain: Eukarya
            Why? Ananas comosus have a true nucleus and membrane bound organelles. This domain contains a variety of species such as ostrich, sea cucumbers, and avocado to name a few.

Kingdom: Plantae
            Why? Ananas comosus are an autotrophic, photosynthetic plant with chloroplasts. All members of this kingdom have cell walls made of cellulose that aid in supporting the plant. The kiwi and the brazil nut are also members of this kingdom.

Phylum: Magnioliophyta
            Why? Ananas comosus are a flowering plant with seeds that develop within the flower’s ovary and becomes a fruit. Another feature members of Magnioliophyta (also known as Anthophyta) have is pollen grains to move the sperm from one flower to another (pollination). The venus fly trap and hot pepper are also members of this phylum.

Class: Liliopsida
            Why? Ananas comosus are monocots, which mean they have one cotyledon, veins on leaves are parallel, fibrous roots, and scattered vascular tissue. The flowers o n these plants usually have petals in multiples of three. The wild yam is also a member of this class. (2)

Order: Poales
            Why? Poales usually grow in sunny and dry regions. Also, a common feature among all Poales is that they have CO2- concentrating mechanisms like C4 photosynthesis or crassulacean acid metabolism (CAM). Ananas comosus is a CAM plant. (3)

Family: Bromeliaceae
            Why? Members of the Bromeliaceae family are of the epiphytic, which means they often grow non-parasitically on another plant. The water absorbing scales that are located on their leaves and stems also characterizes the Bromeliaceae family and help the plants to survive periods of drought. The stems have rosettes of stiff and narrow leaves to collect water. (2)

Why? Members of the subfamily Bromelioideae are defined as being epiphytic and terrestrial plants that have leaves with serrated edges. (2)

Genus: Ananas
            Why? Their sword shaped, tough leaves that grow in a rosette pattern from the crown characterize members of the genus Ananas. They also have fleshy fruits that are made up of many flowers. (7)

Species: Ananas comosus
            Why? Ananas comosus is a tropical plant with a large fleshy fruit. It has stems with rosettes of tough, serrated leaves. The dense terminal leaves for a fruit a syncarp (fleshy compound fruit), and the main axis grows through the fruit and extends to form a crown of tough leaves on top of the fruit. (5)

Phylogenic Trees:

The first phylogenetic tree shows how the Bromeliaceae family fits in the larger scheme of things, going through the Kingdom, Phylum, Class, Order and Family, based mostly on morphology.


The second phylogenetic tree shows how Ananas comosus fits within the Bromeliaceae family. It shows the Family, Subfamily, Genus and Species, and where it fits on the phylogeny of it all. This tree is based mostly one genetics and how each species differ from eachother.
