Reproduction
The Eastern Prickly Pear Cactus has
several means of reproduction. Being an angiosperm (flowering
plant) and a part of the Magnoliopsida (dicots), it produces a
bright yellow, pollen producing flowers.
The pads themselves rise from buds off of the stem or other
existing pads as seen to the left. Learn about another
dicot plant here, the English Ivy.
The brightly colored flowers attract insects such as bumble bees. When the bee lands on the flower, the anthers of the
plant release pollen which sticks to the bee. As it travels from
plant to plant, this pollen gets transferred with it.
In addition to using pollen as a means of reproduction, this
plant also reproduces sexually through seeds. The seeds are
produced through alternation of generations including haploid
and diploid stages of meiosis and mitosis. The seeds are
protected by a bright red colored fruit. These fruits are often
consumed by aerial organisms such as birds. The seeds end up
passing through the bird's digestive system, thus being
dispersed upon defecation. Click here to learn more about
