Sally is examining some untitled diagrams. One diagram shows a cotyledon, primary leaf, and hypocotyls, whereas the other diagram shows presence of coleoptile, primary leaf, and primary root. What do these diagrams depict?

A. germinating seeds of a dicot and a monocot respectively

B. germinating seeds of a monocot and a dicot respectively

C. fertilizing ovules of a monocot and dicot respectively

The diagram depicts the germinating seeds of a monocot and dicot respectively. The correct option is B. Plants that have only one cotyledon are called monocots ['mono' means one]. The structures usually find in germinating seeds of monocots are cotyledon, primary leave and hypocotyls while that of the dicot ['di' means two] plants are coleoptile, primary leave, primary root and especially two cotyledons.
