All plants within a species can interbreed readily and are genetically identical. T F 7. There can be several valid common names for a plant, and many different plants with the same common name. T F 8. Generally speaking, vegetables come from leaves, stems, and roots, while fruits come from the reproductive parts of a plant. T F 9. "Caryopsis" can roughly be thought of as the same as a term for a grain. T F 10. The pericarp develops out of the mesocarp, then becomes the receptacle. T F 11. "Bract" refers to a modified leaf, usually near a flower or inflorescence. T F 12. A perfect flower can be incomplete, but a complete flower cannot be imperfect. T F 13. Compound leaves often have meristematic buds at the base of each leaflet. T F 14. The genus is always capitalized, and the species written in lower-case letters. T F 15. The term "whorl" refers to three or more leaves arising from the node. MULTIPLE CHOICE: Circle the letter which best completes each statement.
