Practice question

Floral diagram provides schematic ground plan transverse section projection illustrating relative number of parts per whorl, degree of fusion connation and adnation, aestivation pattern valvate, twisted, imbricate or vexillary, and overall symmetry radial, bilateral or asymmetric. It depicts bract position, epicalyx, heterostemony and ovary placentation type parietal, axile or free central. However hereditary cytogenetic information such as chromosome count, karyotype, DNA sequence, ploidy level or genome size cannot be inferred from morphology alone. Diagrams serve comparative morphology and identification in systematics.
