Which component of a clam's internal anatomy is a part of the reproductive system?

In clams, the gonads are the specific organs associated with the reproductive system. Clams are generally hermaphroditic, meaning they possess both male and female reproductive structures. The gonads produce gametes, which are the reproductive cells; in males, these are sperm, while in females, they produce eggs. During the spawning season, the release of these gametes into the water aids in external fertilization, a characteristic reproductive strategy in many bivalves.

The other components listed have different primary functions. The kidneys are involved in excretion and osmoregulation, helping to filter waste from the blood. Palps, which are features near the mouth, assist in feeding and handling food particles, while gills serve primarily in respiration, allowing for gas exchange in the aquatic environment. Therefore, the gonadal structure is clearly distinct in its role within the reproductive system of the clam.
