IB Biology Notes - Reproduction Angio HL. 9.3.1 - Structures of a dicotyledonous flower Pollination - The process of pollen transfer from an anther to a stigma. Fertilization - The fusion of a male gamete with a female gamete inside the ovule. This forms a zygote. Seed dispersal - The movement/transport of seeds away from the plant. Figure 9.3.2 - Phaseolus vulgaris seed internal (left) and external (right) structures Germination is the emerging and growth of an embryonic plant from a seed. Water is needed to rehydrate the cells of the seed. The absorption of water is followed by the formation of gibberellin in the embryo's cotyledon. Flowering in long-day and short-day plants is controlled by a pigment called phytochrome. Biology Tutorials - Biology-Online.org. Biology 1B - Lecture 1: Introduction / Fungi.
