1. Reproduction in flowering plants

2. Flower Structure PETALS: These are usually brightly coloured and sometimes scented. They are arranged in a circle or a cylinder. The petals attract insects to the flower, the insects may bring about pollination. CARPEL : These are the female reproductive organs. Each carpel consists of an ovary, bearing of style and a stigma. Inside the ovary there are one or more ovules. The stigma has a sticky surface and pollen grains will stick to it during pollination. The style may be too long or too short. SEPAL: They are often green and much smaller than the petals. They may protect the flower when it is in the bud. STAMEN: These are the male reproductive organs. Each stamen has a stalk called the filament, with an anther at the end. Each anther consists of 4 pollen sacs.

4. Pollination Self-pollination: The pollen which reaches the stigma comes from the same flower or another flower on the same plant. Cross-pollination: Pollen is carried from the anthers of one flower to the stigma in a flower of another plant of the same species. The transfer of pollen from the anthers to the stigma.
