Study the figure and answer the following question. Identify the figure above.

Stamen is the male reproductive organ which consist of a stalk or a filament and anther. Each anther is by bilobed which are attached at the back by a sterile band called connective and each lobe has two chambers, the pollen sacs. The pollen grains are produced in the pollen sacs. Pollen is a fine powdery substance which consists of micro gametophytes and produces the male gametes or the sperm cells. The figure represents anther showing pollen grains.

Study the figure and answer the following question. Name the parts A-C.

Each anther is by bilobed which are attached at the back by a sterile band called connective and each lobe has two chambers, the pollen sacs.

Study the figure and answer the following question. State the function of part A-C.

The third whorl of the flower is composed of stamen, representing the male reproductive organ consisting of a filament and anther. Each anther is by bilobed which are attached at the back by a sterile band called connective and each lobe has two chambers, the pollen sacs. The part labelled A is pollen grain, which is a microscopic body that contains the male reproductive cell of a plant. The main role of pollen is to deliver male gametes (sperm) from the stamen of a plant to an ovule for fertilization of an egg, which then develops into a seed. The part labelled B is pollen sac which produces pollen grains which are male gametophyte containing the male gametes. The part labelled C is filament that is a slender, threadlike object, which functions by supporting the anther.
