Answer 2

Answer:

Now that you know something about the flower and its parts, it is time to dig into some of the "business" end of what a flower does.

As you know, the anther of the stamen produces pollen grains. That in itself is an interesting process that I would discuss in detail with a course for biology majors. For this course, I'll leave it that indeed the anther makes pollen grains.

What is a pollen grain? This structure is almost dust-sized. It has an outer wall that, in some wind-pollinated species, is allergenic to humans. In the photomicrograph below, the thick wall appears somewhat reddish due to a dye used in the preparation of the microscope slide.
