Asexual Reproduction MCQs : This section focuses on the "Asexual Reproduction" in Biology Class 12. These Multiple Choice Questions (MCQs) should be practiced to improve the Biology Class 12 skills required for various interviews (campus interview, walk-in interview, company interview), placement, entrance exam and other competitive examinations.
_____________ is a mode of reproduction in which a new offspring is produced by a single parent.
A. Sexual reproduction
B. Asexual reproduction
C. Bisexual reproduction
D. Nonsexual reproduction
Explanation: Asexual reproduction is a mode of reproduction in which a new offspring is produced by a single parent.
Asexual reproduction is observed in?
A. multicellular organisms
B. unicellular organisms
C. Both A and B
D. None of the above
Explanation: Asexual reproduction is observed in both multicellular and unicellular organisms.
Which of the following is/are features of asexual reproduction?
A. Single parent involved
B. No fertilization or gamete formation takes place
C. This process of reproduction occurs in a very short time
D. All of the above
Explanation: All of the above are features of asexual reproduction.
During binary fission, the parent cell divides into two cells.
C. Can be true or false
D. Can not say
Explanation: True, During binary fission, the parent cell divides into two cells.
___________ is another mode of asexual reproduction exhibited by organisms
A. Binary Fission
Explanation: Fragmentation is another mode of asexual reproduction exhibited by organisms such as spirogyra, planaria etc. The parent body divides into several fragments and each fragment develops into a new organism.
Which of the following undergoes binary fission?
D. Ring worm
Explanation: Amoeba undergoes binary fission. Many single celled organisms undergo binary fission. The diagram depicts the process.
Which of the following is/are the advantages of asexual reproduction?
A. They are unable to adapt to the changing environment
B. Positive genetic influences pass on to successive generations
C. A single change in the environment would eliminate the entire species
D. Since only one organism is involved, the diversity among the organisms is limited
Explanation: Positive genetic influences pass on to successive generations is the advantages of asexual reproduction.
How does hydra reproduce?
Explanation: Hydra reproduces by forming buds externally. It grows and develops tentacles. It eventually separates from the parent and lives an independent life. This process may also be known as fragmentation in hydra since a part of it falls of and starts growing independently.
Budding is the process of producing an individual through the buds that develop on the parent body.
C. Can be yes or no
D. Can not say
Explanation: Yes, Budding is the process of producing an individual through the buds that develop on the parent body.
Which organism undergoes the phenomenon of encystation?
C. Ring worm
Explanation: Amoeba undergoes the phenomenon of encystation. Under unfavorable conditions, amoeba withdraws its pseudopodium and secretes a cyst that covers it.
