The picture below illustrates the life cycle of a sunflower from seedling to maturity. As apparently be shown in the diagram, the developmental process consists of several successive stages, commencing with the seeds being sowed and concluding when the sunflower reaches full maturity.
At the initial stage of life, the seeds are sowed and embedded deeply in the soil. The next stage begins when the seed splits open and breaks through the soil, which enables the seedling to spring up. Once the seedling emerges, it undergoes nutrients absorption by taking in carbon dioxide and releasing oxygen to the environment, which facilitates it to transform into the young plant. During vegetative growth, the young plant shoots up bigger in size and height with more branches elongate and leaves fill out.
When the young plant enters the flowering period, the bud comes out at the top of the plant’s branch. During this time, the bud gradually blooms until the sunflower fully unfolds with bigger petals and stamen. The end of the life phase lasts when the sunflower plant reaches its maturation and gives off scent to attract insects for pollination. The cycle only renews when the mature plant withers and returns nutrients to the soil, paving way for the new seeds to emerge.
