What is the terminal phase of a flower's developmental process called, which includes wilting and shedding of flower parts?

The terminal phase of a flower's developmental process, which encompasses wilting and the shedding of flower parts, is known as senescence. This stage marks the end of the flower's life cycle, where it undergoes physiological changes leading to decay. During senescence, the flower's tissues break down, leading to a visible wilting and ultimately to the abscission of petals and other floral parts. This process is natural and allows the plant to redirect its resources towards new growth or seed production.

Pollination refers to the transfer of pollen from the male part of the flower to the female part, which is crucial for fertilization and the development of seeds, but it occurs much earlier in the developmental timeline. Photosynthesis is the process by which plants convert sunlight into energy, essential for growth and development but unrelated to the wilting or shedding of floral parts. Germination pertains to seeds and the process of a seed developing into a new plant, which is distinct from the lifecycle of an already mature flower.
