Q.
In the diagram of the reproductive system of earthworm A, B, C, D and E represents.
A) A-Seminal vesicle, B-Spermathecae, C-Prostate gland, D-Ovary, E-Accessory gland
B) A- Seminal vesicle, B- Ovary, C- Accessory gland D- Spermathecae, E- Prostate gland,
C) A- Spermathecae, B- Seminal vesicle, C- Accessory gland D- Ovary, E- Prostate gland,
D) A- Spermathecae, B- Seminal vesicle, C- Ovary, D- Accessory gland E- Prostate gland,
Explanation
Earthworm is hermaphrodite. Four pairs spermathecae are located in 6^(th) to 9^(th) segments (one pair in each segment). There are two pairs of testes present in 10^(th) and 11^(th) segment. One pair of ovaries is attached at the inter-segmental septum of the 12^(th) and 13^(th) segments. Two pairs of accessory glands are present one pair each in 17^(th) and 19^(th) segments and a pair of prostate glands in between 17^(th) and 19^(th) segments.
