Save my name, email, and website in this browser for the next time I comment. Some plants use water to move their pollen to other flowers; however, this strategy is uncommon. The pollen grain begins transporting sperm cells from the grain to the ovary when the pollen tube has been fully formed. Most of the pollen grains that are supposed to ensure fertilization happens are wasted in the air. Self-sufficiency. It is uneconomical for plants to create huge, scented, nectar-filled flowers to attract insects. Pollination failure is less likely. The seeds developed when germinated under favorable conditions grow into healthier plants. The term is often used in agriculture, and refers to the transfer of pollen from one plant to another plant of a different variety or species. Cross-Pollination is a type of pollination in which a pollen grain is delivered from the anther of one flower to the stigma of a flower on another plant belonging to the same species. 3.
