Which of the following crops does not require bees at all for pollination?

Corn is the crop that does not require bees for pollination. It is wind-pollinated, which means that its pollen is carried from the male flowers (tassels) to the female flowers (ears) by the wind, rather than relying on animal pollinators like bees. This natural process allows corn to reproduce without the need for pollinators, making it less dependent on the presence of bees in its growing environment.

In contrast, almonds and cranberries rely heavily on bee pollination to produce fruit. Bees significantly increase the yield of these crops. Broccoli does benefit from bee activity as well, though it is primarily self-pollinating. However, while bees can enhance the pollination of broccoli, it can still produce seeds without them, making corn the clear example of a crop that does not require bees for its reproductive process.
