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.
Pollination is the process of moving the pollen from the male components of a plant or flower to the female parts. This fertilizes the female reproductive cells so that a fruit or seeds will develop. Pollen is produced in flowers in the stamens and then must be transferred to the pistil, the female reproductive organ. Pollination may occur within the same flower, which is called self-pollination. Cross-pollination, from one flower to another, is better and produces stronger plants, but it is more difficult. Plants have to rely on wind and animals to transfer pollen from one to another. Animals like bees and hummingbirds that make this transfer, are called pollinators. Pollen in the Garden and Allergies
