Which term refers to the male sex cell of a plant?

• A. Pollen
• B. Flower
• C. Ovary
• D. Petal

Answer: (A)

In plants, the male reproductive element is carried by pollen grains. Pollen grains are produced in the anthers of the flower’s stamen and contain the male gametophyte, which includes the male sex cell. When pollen reaches a compatible stigma, a pollen tube grows and delivers the sperm cells to the ovule inside the ovary, enabling fertilization. The other terms describe different parts or roles: a flower is the entire reproductive structure, the ovary houses ovules and is part of the female side, and a petal is a colorful part of the flower that helps attract pollinators. So pollen is the correct term.
