Muscadine grapes are categorized into two types based on their reproductive structures. What are they?

• A. Male (non-productive) and Female
• B. Self-pollinating and Cross-pollinating
• C. Hermaphrodite and Non-hermaphrodite
• D. Seeded and Seedless

Answer: (A)

Muscadine grapes are dioecious, meaning there are separate plants that produce different types of flowers: male flowers that provide pollen and female flowers that develop into fruit after fertilization. Male flowers don’t form fruit because they lack ovules, while female flowers have ovaries and, once pollen from a male reaches the stigma, fertilization leads to fruit with seeds. This separation of sexes is why you see male (pollen-producing, non-fruiting) and female (fruit-bearing) plants as the two reproductive types. Other options don’t describe the plant’s flower structure. Pollination type (self- vs cross-pollinating) is about how pollen moves, not the flower’s sexual form. Hermaphrodite vs non-hermaphrodite would imply flowers that combine both sexes on one plant, which isn’t the typical classification for muscadines. Seeded vs seedless refers to fruit characteristics, not the reproductive organs of the flowers.
