Answer:
Flowering plants begin as seeds. These seeds store energy and food within them long enough to reach the right environment and germinate. Germination is the development of a plant, growing from a seed into a seedling. Seedlings are the second stage of a flowering plant's life. This is when their roots begin to form and photosynthesis can begin. Next comes the growth period. After the seedling is planted, it requires a lot of food and energy as more leaves begin to emerge. The next stage of a flowering plant's life is the flowering stage itself. This is when buds and flowers begin to sprout. It enters the reproductive stage and pollination begins, allowing more seeds to be sown.
