A zygomorphic flower can be divided into two equal halves by only one plane (bilateral symmetry). Pea flowers exhibit this type of symmetry. \textit{Datura}, chili, and \textit{Petunia} have actinomorphic flowers (radial symmetry).

Scutellum is the single cotyledon in monocot seeds. Non-albuminous seeds (like groundnut) have no endosperm at maturity. Epiblast is a rudimentary cotyledon in some monocots. Perisperm is persistent nucellus tissue in some seeds.
