question 20 (2.5 points)
in flowering plants, pollen grains form in the flowers male parts called

stamens

anthers

carpels

megaspores

endosperms

Explanation:

• Stamens: The stamen is the male reproductive part of a flower. It consists of two parts: the filament (the stalk) and the anther (the part where pollen is produced). So while stamens are the male parts, the specific part where pollen forms is more precisely the anther.
• Anthers: Anthers are the terminal sac - like structures of stamens. They are the sites where microspore mother cells undergo meiosis to produce microspores which develop into pollen grains.
• Carpels: Carpels are the female reproductive parts of a flower. They contain the ovary (where ovules are present), style, and stigma.
• Megaspores: Megaspores are produced in the ovule (within the carpel) through meiosis of the megaspore mother cell. They develop into the female gametophyte (embryo sac).
• Endosperms: Endosperm is a tissue that develops in the seed after fertilization. It provides nourishment to the developing embryo.

Answer:

anthers
