There are many members of the plant kingdom, comprising about 260,000 known species of mosses, liverworts, ferns, herbaceous and woody plants, bushes, vines, trees, and various other forms that mantle the earth and are also found in its waters. They range in size and complexity from small, nonvascular mosses, which depend on direct contact with surface water, to giant sequoia trees, the largest living organisms, which can draw water and minerals through their vascular systems. (Raven) In this paper I just want to outline the major stages of a plant's life cycle. When you plant a seed in the ground, if the soil, water, and temperature are the right combination, a plant starts to grow. The roots grow down and leaves grow up. When the plant is big enough it makes flowers. Flowers help the plant reproduce. When the plant is big enough it makes flowers. Flowers help the plant reproduce by making pollen. The wind blows the pollen or a bee (pollinator) lands on the flower and carries the male pollen to the female part of the flower, called the ovule." Ovule" means "little egg." When the male pollen reaches the ovule it has been fertilized and will grow until it becomes a seed. When you plant this seed in the ground the seeds sprouts, and a new plant grows and makes new seeds, and the plant's life cycle goes on.

In more detail the life cycle of a flowering plant begins when the seed germinates. It progresses through the growth of roots, stems, and leaves; formation of flower buds; pollination and fertilization; and seed and fruit development. The life cycle ends with senescence, or old age, and death. Depending on the species, the life cycle of a plant may last one, two, or many years. Now I understand that when I went to buy flowers and the gardener, I was asked what kind of flowers I wanted, "biennials or perennials . Whatever the life cycle, most plants flower in response to certain cues. A n... Continue Reading
