Flower seeds are the reproductive units of flowering plants, containing the genetic material needed to grow new plants. They come in various shapes, sizes, and colors, depending on the species. When planted in soil and given the right conditions, such as moisture and sunlight, flower seeds can germinate and develop into beautiful flowers. Each flower seed has a protective outer coat that helps it survive until the right conditions for growth are met. Inside, the seed contains an embryo and stored nutrients, which provide energy for the young plant as it begins to grow. Popular types of flower seeds include those from sunflowers, roses, and marigolds.
