**Shortcut Methods and Tricks:**

**Pollen grains:**To estimate the number of pollen grains produced by a single flower, multiply the number of anthers by the average number of pollen grains per anther.**Pollination:**To determine the number of pollen grains required for effective pollination, multiply the number of stigmas in the flower by the number of pollen grains required per stigma.**Fertilization:**To calculate the percentage of zygotes that develop into seeds, divide the number of seeds produced by the number of zygotes formed and multiply by 100.**Germination:**To estimate the germination rate of seeds, divide the number of seeds that germinate by the total number of seeds planted and multiply by 100.
