In this section you can learn more about the characteristics of an angiosperm. The angiosperm is a flowering plant. That is it's characteristic feature. The flowering plant is the dominant form of plant life today. Angiosperms are the source of many raw material, natural products, and food that humans and many other mammals eat. The angiosperm structure has ten major parts. If you look in picture (B) you should be able to see and locate them more easily. There are ten major parts of the angiosperm. On the outside is the covering or protective part of the reproductive organs and the rest of the organs. This part is called the petals. If you look inside the petal you will find the anther, the pollen-bearing part of a stamen. The stigma, the part of the pistil that receives the pollen. The style, a narrow, usually cylindrical and more or less filiform extension of the ovary, which, when present, bears the stigma at its apex. Lastly the filament, the stalklike portion of the stamen, supporting the anthers. Normally you see a green like ball under the flower inside of it is the reproductive organs, such as the ovaries, which are the female reproductive organs, the ovule which is the small egg,and the receptacle, which is what hold all of the organs in. The leaves that branch upward are the sepals. Underneath all of this stuff is the pedicle which is the small stalk that bears the flower. Angiosperms can be both dicot or monocot. Dicot meaning that the flower has the stamens and the pistils in separate flows, either on the same plant or on different plants. Monocot meaning that the flower has both the stamens and the pistils on the same flower. To see examples look at the Microsoft Illustration on dicot and monocot plants. A.) Difference between Monocotand Dicot Plants. B.) The parts of the flower.
