Final answer:
The stalk of an inflorescence is called the peduncle and it connects the inflorescence to the main plant.
Step-by-step explanation:
The stalk of an inflorescence is called the peduncle. It is the main stem of the inflorescence, which supports and holds the individual flowers or flower clusters. The peduncle connects the inflorescence to the main plant.
An example of a peduncle is seen in a sunflower. The tall, sturdy stem that holds the large flower head is the peduncle, allowing the flower to be displayed prominently.
When identifying the parts of a flower, it is important to understand that the stalk of an individual flower is called a pedicel, which attaches the flower to the peduncle.
