@ifeesciencenotes: POLLINATION Definition: Pollination is the transfer of pollen grains from the anther to the stigma of a flower of the same species. Types of Pollination: 1. Self-pollination This occurs when pollen is transferred from the anther to the stigma of the same flower or another flower on the same plant. 2. Cross-pollination This occurs when pollen is transferred from the anther of one plant to the stigma of a flower on a different plant of the same species. Agents of Pollination: • Wind • Water • Insects (e.g. bees, butterflies) • Birds • Other animals Structure of a Flower (Main Parts): • Anther - produces pollen grains • Stigma - receives pollen • Style - connects stigma to ovary • Ovary - contains ovules • Ovules - develop into seeds • Petal - attracts pollinators • Sepal - protects the flower bud • Pedicel - supports the flower Importance of Pollination: 1. It leads to the formation of seeds and fruits. 2. It is essential for the reproduction of flowering plants. 3. It helps maintain the balance of ecosystems.
