Introduction:-
Structure of anther:- An anther is the male reproductive structure found in the flower of angiosperm plants. It consists of several key parts:
1. Filament: This is a slender stalk that supports the anther and positions it above the flower’s receptacle.
2. Anther lobes: Anthers typically have two lobes (anther sacs) that contain pollen-producing cells. These lobes are connected to the filament.
3. Pollen sacs: Inside each anther lobe, there are pollen sacs, also known as microsporangia. These sacs contain pollen grains, which are the male gametophytes of the plant.
4. Connective: The connective is a tissue that joins the two anther lobes. It plays a role in the dehiscence (opening) of the anther to release pollen.
5. Pollen grains: These are tiny structures produced within the pollen sacs of the anther. Each pollen grain contains the male reproductive cells (sperm) necessary for fertilization.
The anther’s primary function is to produce and release pollen, which can be carried by wind, insects, or other pollinators to the female reproductive structure (the stigma) of a flower, enabling fertilization and the formation of seeds.
