What does a stem on flower do?

The stem of a flower, also known as the peduncle, supports the flower and elevates it to facilitate pollination by making it more accessible to pollinators like bees and butterflies. It also transports water, nutrients, and sugars between the roots and the flower, playing a crucial role in the plant's overall health and growth. Additionally, the stem helps to stabilize the flower, allowing it to withstand environmental factors such as wind or rain.
