The male part of a plant is called the stamen. It's not held by anything, but it is part of the flower, which is the reproductive structure of the plant.

Here's a breakdown of the parts:

* Stamen: This is the male reproductive organ. It consists of two main parts:

* Anther: This is the top part of the stamen where pollen is produced.

* Filament: This is the stalk that supports the anther.

* Flower: The flower is where the stamen is located, along with the female reproductive organ called the pistil.

So, while there isn't a specific thing that "holds" the stamen, it is supported by the flower and its structure.
