Are cashew nut walnut almond parthenocarpic fruits?

No, cashew nuts, walnuts, and almonds are not parthenocarpic fruits. Parthenocarpy refers to the development of fruit without fertilization, leading to seedless fruit. Instead, cashew nuts are the seeds of the cashew Apple, while walnuts and almonds are seeds of their respective fruits, all of which typically require pollination for proper fruit development.
