Give reasons : (i) Test tube baby programme is a boon to infertile couples.

Differentiate between : Sperm duct and fallopian tube (Function).

Fertilisation in humans is practically feasible only if i.The ovum and sperm are transported simultaneously to ampullary-isthmic junction of the cervix. ii.The sperm are transported into cervix within 48 hours of release of ovum in uterus. iii.The sperm are transported into vagina just after the release of ovum in fallopian tube. iv.The ovum and sperm are transported simultaneously to ampullary-isthmic junction of the fallopian tube.

(ii) Rupture of follicle and release of ovum from the ovary (iii) Monthly discharge of blood and disintegrated tissues in human female. (iv) Process of fusion of ovum and sperm. (v) Fixing of developing zygote on the uterine wall. (vi) The permanent stoppage of menstruation at about the age of 45 years in a female. (b) State the functions of the (0) Placenta (ii) Amniotic fluid. [ICSE 2004, 2015] (c) Using the symbol "X' indicates the region in the diagram where fertilisation occurs.[ICSE 2004)

A: In test-tube baby programme, ova from wife/donor (female) and sperms from the husband/donor(male) are collected and induced to form zygote under simulated conditons in laboratory. R: Embryos with more than 8 blastomees are then transferred to fallopian tube (ZIFT) to completes its further development.

Assertion : In test-tube baby program, ova from wife/donor (female) and sperms from husband/donor (male) are collected and are induced to form zygote under simulated conditions in laboratory. Reason : Embryos with more than 8 blastomeres are then transferred to fallopian tube (ZIFT) to complete its further development.

Identify development stage and place of occurrence. (a) Blastocyst, uterine wall (b) 8-celled morula, starting point of fallopian tube (c) Late morula ,middle part of fallopian tube (d) Blastula, end part of fallopian tube.
