Male pollen is produced by the stamen, the male reproductive structure found in flowering plants. This pollen contains the male gametes, or sperm cells, that are needed to fertilize a plant's ovules and produce new seeds. After the pollen is made, it is often picked up by pollinators like bees and carried to other plants, which can lead to fertilization. However, some of this pollen can also escape into the atmosphere and float around until it lands on another plant.While male pollen can theoretically lead to fertilization without the help of pollinators, it's important to remember that this process is far less reliable than when pollinators are involved. (Pollinators are bees, butterflies, bats, hummingbirds, and beetles: Bees are the most well-known pollinators. They are responsible for pollinating over 70% of the world's crops!). The pollen must land on a receptive stigma, the female reproductive structure to successfully fertilize a plant. If the pollen floats away or lands on a non-receptive stigma, fertilization won't occur. Furthermore, the chances of male pollen landing on a nearby plant that's compatible with it are pretty slim.
