Name the respective part of human female reproductive system: (i) that produces eggs. (ii) where fusion of egg and sperm take place, and (iii) where zygote implanted. (b) Describe in brief what happen to the zygote after it gets implanted.

Given below are diagrams showing the different stages in the process of fertilisation of an egg in the human female reproductive tract. Study the diagrams and answer the questions (i) Arrange the letters given below each diagram in a logical sequence to show the correct order in the process of fertilisation. (ii) Where does fertilisation normally take place? What is 'Implantation' that follows fertilisation ? (iii) Mention the chromosome number of the egg and zygote in humans. (iv) Explain the term 'Gestation'. How long does Gestation last in humans ? (v) Draw a neat, labelled diagram of a mature human sperm.

Site where release of second polar body in humans occur is: 1) Body cavity 2) Uterine cavity 3) Fallopian tube 4) Ovary

Given below is a diagram of the reproductive system of a human female : (i) Name the parts numbered 1-6. (ii) Normally after how many days does an ovary release an egg? (iii) Where are the sperms released during coitus? (iv) What do the sperms do after being released ? (V) What is the function of the organ numbered 5 ? (vi) How many days does it normally take from the fertilisation of the egg up to the birth of the baby?

Select correct statements related to the human female reproductive system i. The wall of the uterus has three layers of tissue i.e., mesometrium, ii. The endometrium is the inner glandular layers that lines the uterine cavity. iii. Myometrium is the middle thick layer of smooth muscle which exhibits strong contraction during delivery of the baby. iv. The endometrium undergoes cyclical changes during the menstrual cycle. (a) i and iv (b) ii and iv (c) ii, iii and iv (d) i,ii,iii and iv

Study the diagram given below and then answer the questions that follow : (i) Name the part labelled A. Name any two hormones produced by the part labelled A. (ii) What happens to the part labelled B if : (1) fertilisation takes place? (2) fertilisation does not take place ? (iii) Where does fertilisation occur ? (iv) Draw a neat diagram of the human sperm as seen under high magnification and label the following parts: (a) Acrosome (b) Mitochondria.
