We have already examined the anatomical details of the stems, leaves, and roots of members of the Angiosperms in previous sections.
What sets the flowering plants (angiosperms) apart from the rest of the plants we have looked at? The flower is the distinguishing feature (the ‘flowering plants’). In the majority of the angiosperms each flower contains both male and female parts, that is, the flower is bisexual. In some species, however, either the male or the female parts are lacking and the individual flower is male (staminate) or female (carpellate). If both staminate and carpellate flowers grow on the same plant the species is termed monoecious; if the male and female flowers grow on separate plants the species is termed dioecious. The shape, arrangement, and number of floral parts are useful features for identification, and depending on the pollinating agent, some or all of these parts may be variously modified.
