Plant development refers to the series of processes that a plant undergoes from a seed to a mature organism. This includes germination, where the seed absorbs water and begins to grow, followed by the formation of roots, stems, and leaves. Each stage is influenced by environmental factors such as light, temperature, and water availability, which help determine the plant's growth patterns. During development, plants also undergo differentiation, where cells become specialized for specific functions. For example, some cells may develop into xylem for water transport, while others become phloem for nutrient distribution. This specialization is crucial for the plant's overall health and ability to adapt to its surroundings.
