The term 'pollen-bearing part' refers to the male reproductive organs of a flower, which are the anther (6 letters) and the STAMEN (6 letters). The anther is the part of the flower that produces and contains pollen, while the STAMEN is the stalk that supports the anther. Together, the anther and STAMEN are responsible for producing and dispersing pollen, which is necessary for the fertilization of flowers and the production of seeds.
