Question

which parts of the flower are included in the stamen? sepal, stem, ovary stigma, style, ovary petal, receptacle anther, filament

Explanation:

To determine the parts of the stamen, we recall flower anatomy: the stamen is the male reproductive structure of a flower, consisting of the anther (which produces pollen) and the filament (which supports the anther). Let's analyze each option:

• "Sepal, stem, ovary": Sepals are part of the calyx, the stem is not a stamen part, and the ovary is part of the pistil (female structure). Eliminate this.
• "Stigma, style, ovary": These are all parts of the pistil (female reproductive structure), not the stamen. Eliminate this.
• "Petal, receptacle": Petals are part of the corolla, and the receptacle is the base of the flower; neither is part of the stamen. Eliminate this.
• "anther, filament": As per flower anatomy, these are the two components of the stamen.

Answer:

anther, filament
