Flower buds are the early stages of flowers, typically appearing as small, closed structures on plants. They contain the developing flower parts, including petals, stamens, and pistils, which will eventually open up to reveal the full bloom. Buds can vary in size, shape, and color depending on the species of plant. As the plant grows and conditions become favorable, the flower bud will mature and open, allowing for pollination. This process is crucial for the reproduction of flowering plants, also known as angiosperms. Flower buds can be found on many types of plants, including roses, tulips, and sunflowers.
