Detailed explanation-1: -Plants with smaller flowers use self-pollination. Peanuts, wheat, apricots, rice, tomatoes are some examples of self-pollinating plants.

Detailed explanation-2: -Not all perfect flowers self-pollinate without help; some require and many benefit from the assistance of pollinating insects according to Encyclopedia Britannica.

Detailed explanation-3: -Among other plants that can self-pollinate are many kinds of orchids, peas, sunflowers and tridax. Most of the self-pollinating plants have small, relatively inconspicuous flowers that shed pollen directly onto the stigma, sometimes even before the bud opens.

Detailed explanation-4: -Which Plants Are Self-Pollinating? Many, but not all, crops are self-pollinating. This includes: beans), broccoli, cabbage, carrots, cauliflower, corn, kohlrabi, onions, and peppers. Fruit trees also self-pollinate including apples, cherries, peaches, and pears.

Detailed explanation-5: -In general, in contrast to diploid roses which are mostly self-incompatible, tetraploid roses are self-compatible. To prevent self-pollination of the selected seed parent, the anthers (pollen sacs) must be removed from the blooms before any pollen is released (Fig. 1).
