naked seeds born in cones), Angiosperms (flowering plants and seeds develop in
fruits)
• Subclass—Dicotyledonae (Dicot), which has two cotyledons and reticulate leaf
venation (such as a bean plant), Monocotyledonae (Monocot), which has only one
cotyledon and parallel leaf venation (such as corn)
• Order
• Family—grouped based on natural plant relationships using structural and cultural
similarities
• Genus—grouped based on morphology and genetic, biochemical, and molecular
relationships
• Species—grouped with even greater refinements than genus but still based on same
relationships as in genus
• Cultivar—cultivated variety (such as a "Delicious" apple)
