The final stage of a plant's life cycle is when it reaches maturity, becoming a mature plant. At this stage, the plant has completed its growth and development processes. It can produce flowers and seeds, thereby ensuring that the life cycle can continue. The mature plant is crucial for reproduction, as it is responsible for generating the next generation of seeds, which will eventually germinate and begin the life cycle anew.

In contrast, the seedling stage refers to an early period of growth after germination, while pollination is a specific process that allows for fertilization to occur, but does not represent a stage in the plant's life cycle per se. Germination is the process of a seed developing into a new plant, which is also an early stage. Therefore, recognizing the mature plant as the final stage encompasses the entirety of the plant's lifecycle from seed to growth and reproduction.
