How to Hard-Boil an Egg. Hard-boiling eggs is almost as easy as boiling water, if you know the right process: Cooking eggs too long or too vigorously can result in cracked shells, tough whites, and green-gray, sulfuric-smelling yolks.
Although all flowering plants rely on pollination for reproduction, there is a variation in how plants pollinate. There are two types of pollination called self-pollination and cross-pollination. Self-pollination is the more basic type of pollination because it only involves one flower.
Most flowering plants are hermaphroditic, with both male and female parts in one flower. Pollination in these plants involves the pollen moving from the stamen to the stigma inside each flower. The remainder of flowering plants have either male flowers, female flowers, or both.
