  2. Ovum
  3. (d) Urethra
  4. (c) Urethra
  5. (c) Testes
    1. False
    2. True
    3. True
    4. False
    5. False
  6. The tail in the sperm is long and tapering of helps in the movement of sperm in the fallopian tube during fertilisation process.
  7. Fishes and frogs lay hundreds of eggs & release millions of sperms in water, but all eggs do not get fertilised & develop into new individuals. This is because the eggs & sperms get exposed to water movement, wind & rainfall. Also there are other animals in ponds which may feed on eggs. Thus, production of large number of eggs & sperms is necessary to ensure fertilisation of at least a few of them. In contrast to this, a hen’s egg get fertilized every time it lays & develops into a young chick.
  8. In female reproductive system, after fertilization, the embryo gets embedded in the uterus for further development.
  9. Importance of reproduction in organisms:
    Living organisms reproduce to maintain their number & for ensuring the continuance of their kind, generation after generation. It replaces old and dying ones by young ones later these young ones feeds, grows and reproduces again to sustain their number. Hence, reproduction is the fundamental feature of all living organisms. It is the means by which life goes on. Life would not exist if organisms did not reproduce.
