Answer: B
Explanation: Sexual reproduction involves the fusion of male
and female gametes, leading to the formation of offspring with genetic material
from both parents.
Answer: A
Explanation: Budding is a form of asexual reproduction where a
new organism develops from a bud or outgrowth on the parent organism.
Answer: B
Explanation: In fishes, external fertilization occurs when the
male releases sperm over the eggs released by the female in the water.
Answer: B
Explanation: Fragmentation is a form of asexual reproduction
where an organism's body breaks into fragments, each of which grows into a new
individual.
Answer: B
Explanation: Gametes (sperm and egg) are haploid cells, meaning
they contain half the number of chromosomes of the parent organism.
Answer: C
Explanation: Vegetative propagation is a type of asexual
reproduction where new plants grow from parts of the parent plant, such as
stems, leaves, or roots.
Answer: B
Explanation: Parthenogenesis is a type of asexual reproduction
where offspring are produced from unfertilized eggs, without the involvement of
male gametes.
Answer: C
Explanation: Amoeba reproduces by binary fission, where the
cell divides into two identical daughter cells.
Answer: A
Explanation: Both males and females produce gametes (sperm and
eggs, respectively) for sexual reproduction.
Answer: D
Explanation: Fertilization is a sexual reproduction process
where gametes combine to form a zygote, not a method of asexual reproduction.
Answer: A
Explanation: The primary function of the male reproductive
system is to produce and deliver sperm, which are the male gametes.
Answer: B
Explanation: Oviparous organisms lay eggs outside the body
where development occurs, such as birds and reptiles.
Answer: B
Explanation: In vegetative propagation, the formation of a new
plant does not involve the male gamete, as new plants grow from parts of the
parent plant.
Answer: C
Explanation: The anther produces pollen, which contains male
gametes (sperm cells) in flowering plants.
Answer: B
Explanation: In external fertilization, eggs and sperm meet
outside the female body, as seen in fishes and amphibians.
Answer: B
Explanation: Frogs are examples of organisms that exhibit
external fertilization, where the female lays eggs and the male fertilizes them
outside the body.
Answer: C
Explanation: In humans, fertilization typically occurs in the
fallopian tube, where the sperm meets the egg.
Answer: C
Explanation: Asexual reproduction allows for rapid population
increase, as only one organism is needed for reproduction.
Answer: D
Explanation: Pollination is a process involved in sexual
reproduction, not a method of asexual reproduction.
Answer: A
Explanation: Planaria can regenerate lost parts of their body,
a form of asexual reproduction.
Answer: B
Explanation: Parthenogenesis is a type of asexual reproduction
where an organism develops from an unfertilized egg.
Answer: B
Explanation: Viviparous organisms give birth to live young,
with internal fertilization and development inside the mother's body.
Answer: C
Explanation: Binary fission is the process in which a
single-celled organism divides into two identical daughter cells.
Answer: B
Explanation: External fertilization typically occurs in aquatic
environments where both eggs and sperm are released into the water.
Answer: B
Explanation: Ovoviviparity occurs in sharks, where the eggs
develop inside the female’s body and the young are born live.
Answer: C
Explanation: The testes are responsible for producing sperm in
males.
Answer: D
Explanation: Gametes are haploid, not diploid, as they contain
half the number of chromosomes of the parent organism.
Answer: C
Explanation: The ovary is the female reproductive organ in
flowering plants, which contains the ovules.
Answer: A
Explanation: The haploid generation is the gametophyte, which
produces gametes.
Answer: B
Explanation: In humans, after fertilization, the embryo
implants itself in the lining of the uterus for further development.
Answer: A
Explanation: Oogenesis involves the formation of one functional
haploid egg and polar bodies, which are non-functional.
Answer: B
Explanation: The sperm’s head contains the nucleus with genetic
material, and the mitochondria are found in the neck region, providing energy
for the sperm’s movement.
Answer: C
Explanation: In humans, fertilization typically occurs in the
fallopian tube, where the sperm meets the egg.
Answer: C
Explanation: The testes are the male reproductive organs
responsible for the production of sperm (male gametes).
Answer: A
Explanation: After ovulation, the corpus luteum secretes
hormones like estrogen and progesterone, which maintain the uterine lining for
possible pregnancy.
Answer: A
Explanation: Pollination is the transfer of pollen from the
male anther to the female stigma of a flower, leading to fertilization.
Answer: C
Explanation: Regeneration involves the growth of new parts of
the body from fragments or lost parts of an organism.
Answer: B
Explanation: The zygote is diploid, as it results from the
fusion of two haploid gametes, one from each parent.
Answer: C
Explanation: The anther is part of the male reproductive organ
(stamen) in a flower and is responsible for producing pollen grains.
Answer: B
Explanation: In honeybees, parthenogenesis is observed where
unfertilized eggs develop into males (drones), and fertilized eggs develop into
females (workers or queens).
Answer: B
Explanation: In humans, fertilization typically occurs in the
fallopian tube, where the sperm meets the egg.
Answer: B
Explanation: Rooting of stem cuttings is a method of vegetative
propagation where a new plant grows from a part of the parent plant.
Answer: C
Explanation: Internal fertilization occurs in humans, where
sperm is deposited inside the female reproductive tract, and fertilization takes
place within the body.
Answer: C
Explanation: The male gamete in plants is contained in the
pollen grain, which fertilizes the ovule to form seeds.
Answer: A
Explanation: Binary fission is an asexual reproduction method
where a single organism divides into two genetically identical daughter cells.
Answer: C
Explanation: The umbilical cord connects the fetus to the
placenta and allows the exchange of nutrients, gases, and waste products.
Answer: B
Explanation: Hydra reproduces through budding, where a new
individual develops from an outgrowth or bud on the parent organism.
Answer: A
Explanation: Frogs reproduce via external fertilization, where
eggs and sperm meet outside the female body in an aquatic environment.
Answer: C
Explanation: Spores are asexual reproductive bodies produced by
some plants and fungi that can grow into new organisms without fertilization.
Answer: A
Explanation: The fertilized egg in humans is called a zygote,
which undergoes further divisions to form the morula, blastocyst, and eventually
the embryo.
