Parthenocarpy is the development of fruit without fertilization, resulting in seedless fruits. This phenomenon can occur naturally or be induced artificially using plant hormones. Common examples include bananas and seedless grapes. These fruits are commercially valuable because they are easier to eat and often preferred by consumers. In normal fruit development, fertilization triggers seed formation. In parthenocarpy, this step is bypassed, but fruit growth still occurs. Other options are incorrect because parthenocarpy specifically refers to seedless fruit production. Thus, seedless fruit is the correct answer. This concept is important in botany and agriculture, especially in improving crop quality and market value.
