What is true about ants in a colony?

In the context of ant colonies, the correct statement is that only reproductive forms have wings. This generally refers to the queen and male ants, which are the only members of the colony that develop wings. These winged ants take part in a reproductive process called nuptial flight, where they mate and subsequently establish new colonies.

Workers, which are the non-reproductive females, do not have wings and are primarily responsible for foraging, caring for the queen's offspring, and maintaining the nest. Therefore, the presence of wings is a characteristic limited to the reproductive castes and not a feature of the worker ants. This distinction is crucial for understanding the roles and physical characteristics within an ant colony.

The other options do not accurately represent the structure of ant colonies. For instance, the notion that all ants or only workers have wings is incorrect since worker ants are wingless, highlighting the importance of recognizing the specific roles and attributes of different castes within the colony. Additionally, workers do not produce eggs; that role belongs solely to the queen.
