Angiosperms can be monocot or dicots and that you canrecognize those differences in the flowers of those two types of plants. I need to find out any other major differences you couldfind between two flowers, could it be asexual v. sexual orself-pollination v. external pollination or something elseentirely. When an anther is a significant amount lower than thestigma could that result in a plant not unable toself-pollinate.
