In which of the following groups, are all plants monoecious?

Correct option is C

The Correct Answer is (c) Maize, Cucumber, Fig, and Melon

A monoecious plant is one that bears both male and female reproductive organs on the same plant but in separate flowers. The correct group that consists entirely of monoecious plants includes Maize, Cucumber, Fig, and Melon.

• Maize (Zea mays) – Monoecious, with separate male (tassel) and female (ear) flowers on the same plant.
• Cucumber (Cucumis sativus) – Monoecious, having both male and female flowers on the same vine.
• Fig (Ficus carica) – Monoecious in some varieties, though dioecious in others.
• Melon (Cucumis melo) – Monoecious, producing separate male and female flowers on the same plant.

Information Booster:

• Monoecious plants have separate male and female flowers on the same plant (e.g., Maize, Cucumber).
• Dioecious plants have male and female flowers on separate plants (e.g., Papaya, Poplar).
• Examples of Monoecious Plants: Maize, Cucumber, Melon, Pumpkin, Coconut, Walnut.
• Examples of Dioecious Plants: Papaya, Date Palm, Poplar, Cannabis, Spinach.

Additional Information:

• Papaya and Poplar are dioecious, meaning male and female reproductive structures are present on different plants.
• Rose is hermaphroditic, meaning each flower has both male and female parts.
• Fig species vary; some are monoecious, but many are dioecious.
