Which type of vegetable requires no pollination?

Cabbage is the correct answer because it can produce edible heads without the need for pollination. Cabbage is a member of the Brassica family and it is typically grown for its tightly packed leaves. In terms of reproduction, many varieties of cabbage are capable of forming heads even if pollen is not transferred between flowers, which allows for self-fertilization and development without external pollinators.

Conversely, sweet corn relies on wind pollination to effectively develop its kernels, as each ear of corn requires pollen from the tassels to fertilize the ovules. Peppers also need pollination, though they can self-pollinate, they can benefit from cross-pollination to improve fruit set and yield. Tomatoes are known to be self-pollinating; however, they still typically benefit from the movement of pollen, facilitated by wind or insects, especially in terms of increasing fruit production and quality. Thus, cabbage stands out as the vegetable that does not require pollination for its edible crop.
