Anthophyta- Helianthus annuus 

The plants in Phylum Anthophyta are flowering plants, either herbaceous or hardwoods.  These plants are the most advanced of all plant forms.  The organisms are heterosporous seed plants.  Since the sperm is not motile, the sperm is conducted to an egg by a pollen tube.  The seeds on these plants are enclosed within a fruit.  The flowers are the means of reproduction, with ovules which are surrounded by two integuments.  The double fertilization leads to the formation of polyploidy endosperm tissue.  The plants posses stamens with two pairs of pollen sacs, sieve tubes and companion cells in the phloem, or vessels in the xylem.

Phylum Anthophyta plants dominate the vegetation of the modern world.  They have developed adaptations that made them more successful in the competition for a place in the sun, which makes them more widely grown.  The organisms are dominant in most terrestrial ecosystems outside of boreal forest.

Examples of organisms in the Phylum Anthophyta include: angiosperms (flowering plants)

The Phylum Anthophyta contains two classes: Monocotyledonae and Dicotyledonae.
