(b) Both A and R are true but R is not the correct explanation of A.
(c) A is true but R is false.
(d) A is false but R is true.
6. .Assertion(A): Testes lie in penis outside the body. 1
Reason (R) : Sperms require temperature lower than the body temperature for
development.
7. Assertion(A) : Asexual reproduction is a primitive type of reproduction. 1
Reason (R) : Asexual reproduction involves only mitotic cell division.
8. In which of the following organisms, multiple fission is a means of asexual 1
reproduction?
(a) Yeast

(b) Leishmania
(d) Plasmodium
II. Answer the following. 5x2=10
1 Write difference between asexual and sexual reproduction. 2
2 What is placenta? Mention its role during Pregnancy. 2
3 List two functions of ovary of Female 2
reproductive System. How Can Pregnancy
be Prevented Surgically?
4. a) Name the reproductive and non-reproductive 2
part of bread mould (Rhizopus).
b) List any two advantages of vegetative propagation.
Study the diagram given below :-
5. Identify the process and which organism 2
uses the above method for reproduction?
Answer the following. 4x3=12
1 i) Name the mode of reproduction of the Following 3
Organisms and State the important Features of
each mode.
a) Planaria & Hydra (1)
ii) We can develop new plants from the leaves of Bryophyllum. Comment
iii) List two advantages of vegetative propagation
over other modes of reproduction.
2 Name the part marked A in the diagram. 3
ii) How does A reach part B?
iii) Write names of those parts of Flower
which serve the same function as the Following do in the animals
is testes B) Sperm (iii) Ovary iv) egg
3 i) How many eggs are produced every month by either of the ovaries in a human 3
female? Where does Fertilization takes place in the Female reproductive
System?
ii) what happens in case the egg released by the ovary are not Fertilised?
4 i) Suggests three Contraceptive methods to control the size of human population. 3
ii) Mention the factors that determine the Size of population.
III Answer the following. 5x2=10
1 The Female reproductive system includes the ovaries, Fallopian tubes, uterus, 5
vagina and mammary glands.
These organs are involved in the production and transportation of gametes and
the production of sex hormones. The Female reproductive system also facilitates
the Fertilisation of ova by sperm and supports the development of offspring
during Pregnancy and infancy.
i) In which part does:
a) Fertilisation take place
Diagram:
b) foetus develop
ii) which structures in human Female are equivalent to the following structure in
the male?
a) Testes
b) vas deferences
In each case say in what respect the structures are equivalent?
2 i) Use of a condom is beneficial for both the sexes involved in a sexual act. 5
Justify this statement giving two reasons.
ii) How do oral contraceptives help in avoiding pregnancies?
iii) What is sex selective abortion? How does it affect a healthy society? (State
any one consequence).
(OR)
Why are budding, fragmentation and regeneration all considered as asexual
types of reproduction?
With neat diagram explain the process of regeneration in Planaria.
