उत्तर
The anther contains pollen grains.
Explanation:
An anther contains male gametes called pollen grains. An anther is a component of a flower's stamen, which is its male reproductive organ. Anthers are bilobed and have four pollen sacs in the majority of plants. These pollen sacs undergo meiosis, which results in the production of haploid pollen grains.
