Presentation on theme: "Flower Structure and Function"— Presentation transcript:
1Flower Structure and Function Leaf-like structures at the base of the flower are called sepals.They enclose the flower before it opens.They are usually green.
2Inside the sepals are leaf-like blades called petals. They are often white or brightly colored.They surround and protect the reproductive parts.They attract insects to the flower.
3A stamen is the male reproductive part of the flower. Each stamen has a long thin stalk called a filament.The filament supports the anther.The anther is a sac at the end of the stamen that produces pollen.
4A pistil is the female reproductive part of a flower. The enlarged base is called an ovary.The ovary contains ovules that produce eggs.The slender stalk of the pistil is called a style.The style supports the stigma, the sticky end of the pistil that collects pollen.
17Asexual reproduction in plants As only one parent is involved in asexual reproduction, all the offspring have exactly the same genes as their parent.The offspring are identical.Because of this, any genetic problems there may be will always be passed on to the new generation.
18StemsIn some species, stems arch over and take root at their tips, forming new plants.Wild strawberries do this.
19Roots Some plants use their roots for asexual reproduction. The dandelion is a common example.They send up new stems from their roots.
20LeavesSome plants can produce tiny plantlets that fall off and can take up an independent existence.Bryophyllum (Kalanchoë) is an example.
