these plants are not angiosperms.
there is no double fertilization in them.
endosperm is not formed in them.
endosperm gets used up by the developing embryo during seed development.

Each stamen which represents the male reproductive organ consists of a stalk or a filament and an anther.
An actinomorphic flower can be dissected into two equal halves from any plane.
Superior ovary is found in hypogynous flowers.
When stamens are attached to the petals, they are epiphyllous as in brinjal.
