Petals Brightly coloured and conspicuousmodified leavestoattractinsectsfor pollination and provide aplatformforinsects to land. Stamen Consists ofanther and filament; anther has 2 lobes,eachcontains 2 pollen sacs which producepollen grains.The pollen grain containstwo male gametes. Carpel (pistil)Consists of one or morestigmaswhich capture pollengrains,astyle through which pollen tube grows, and an ovary whichcontains ovules.The ovum is in the ovule.
