Answer
(a) The reproductive cells A and B are:
- A → Ovum
- B → Sperm
(b) Parts of the reproductive system where the above cells are produced are:
- Sperms are produced in the testis.
- The ovum is produced in the ovary.
(c) The reproductive cells unite in the fallopian tubes of the female reproductive system.
(d) The main hormone secreted are:
- Ovary → Oestrogen and progesterone
- Testis →Testosterone
(e) Accessory glands found in the male reproductive system along with their functions are mentioned below:
- Seminal vesicle — They produce a secretion which serves as a medium for the transportation of the sperms.
- Prostate gland — It produces an alkaline secretion which mixes with the semen and helps neutralise acid in female's vagina.
- Bulbo-urethral gland — They produce a secretion which serves as a lubricant.
