The other way is called apomixis, and that means that the seeds are produced without fertilization. Seeds develop in the seed pod (ovary), the swelling just behind the flower petals. But if later in the year conditions change and become harsh, the organism can switch to sexual reproduction to create a population that is more diverse and therefore, better able to withstand the varied conditions.

The genetic constitution of formed individuals remains the same as the parent cell. Botanists call this phenomenon the alternation of generations. Some fish also practice, and this is really cool: sequential hermaphroditism. Sexual reproduction is good for creating a diverse gene pool that can withstand a dynamic and changing environment. Reproductions in a laymans language can be described as a means to ensure the survival of the species. Both methods have advantages.
