Question

Which of the following structures is incorrectly paired with its function?

Options

• Gonads - gamete producing organs

• Spermatheca - sperm-transferring organ found in male insects

• Cloaca - common opening for reproductive, excretory, and digestive systems

• Endometrium - lining of the uterus, forms maternal part of placenta

Answer 1

Spermatheca - sperm-transferring organ found in male insects

Explanation:

• Gonads are correctly paired as gamete-producing organs.
• Spermatheca is not a sperm-transferring organ found in male insects; it is actually a sperm-storage organ found in female insects.
• Cloaca is correctly identified as a common opening for reproductive, excretory, and digestive systems.
• Endometrium is correctly described as the uterine lining forming the maternal part of the placenta.
