• A. a - pedicel, b - anther
• B. a - petiole, b - microsporangia
• C. a - peduncle, b - pollen sac
• D. a - filament, b - anther

Answer 1

The correct option is D a - filament, b - anther

The stamen is the male reproductive organ in flowers. The whorl of stamens forms the androecium.
A typical stamen consists of two parts:
●Anther
●Filament

An anther is a bilobed structure and each lobe has two pollen sacs (microsporangia) that consist of sporogenous tissue in the center. It produces the male gametophytes (pollen grains).

Filament is a slender stalk which possess anther at the tip.

Pedicel is the stalk that connects the individual flower to the plant stem.

Petiole is the part of a leaf that connects the leaf blade to the plant stem.

Peduncle is the main stalk of an inflorescence.

(D) a - filament, b - anther
