Question

Which of the following structures stores sperm in earthworms during copulation?

• A. Testes
• B. Spermatheca
• C. Vasa deferentia
• D. Seminal vesicles

Answer 1

The correct option is B Spermatheca

One pair of spermatheca are located in each segment from 6th-9th segments. The spermatheca stores sperms that the earthworm receives from its mate during copulation.
The immature sperms (spermatozoa) are produced by the testes.
The spermatozoa mature in the seminal vesicle and are stored there until copulation occurs.
The vasa deferentia is the spermatic duct which carries the mature sperm to the prostate gland.
