Here are 10 sample questions. Start a quiz to get randomized questions with scoring.
Q1
Easy
Which of the following is an example of asexual reproduction?
A.
Budding in yeast
B.
Pollination in plants
C.
Fertilization in animals
D.
Seed dispersal in plants
Show Answer & Explanation
Correct Answer: A
Budding in yeast is a form of asexual reproduction where a new organism develops from an outgrowth or bud on the parent organism.
Q2
Easy
Which organism reproduces asexually through binary fission?
A.
Bacteria
B.
Fungi
C.
Plants
D.
Animals
Show Answer & Explanation
Correct Answer: A
Bacteria reproduce asexually by binary fission, where a single cell divides into two identical daughter cells.
Q3
Easy
What type of asexual reproduction involves the fragmentation of the parent organism?
A.
Budding
B.
Fragmentation
C.
Spore formation
D.
Vegetative propagation
Show Answer & Explanation
Correct Answer: B
Fragmentation is a form of asexual reproduction where the organism breaks into fragments, each capable of growing into a new individual.
Q4
Medium
What is the primary advantage of asexual reproduction?
A.
Genetic diversity
B.
Rapid population increase
C.
Requires two parents
D.
More energy consumption
Show Answer & Explanation
Correct Answer: B
Asexual reproduction allows for rapid population increase since offspring are produced from a single parent without the need for mating, leading to quicker colonization of environments.
Q5
Medium
In which of the following organisms does budding occur?
A.
Baker's yeast
B.
Earthworm
C.
Human
D.
Hydra
Show Answer & Explanation
Correct Answer: A
Budding is a form of asexual reproduction commonly found in yeast, where a new organism develops from an outgrowth or bud on the parent organism, making Baker's yeast the correct choice.
Q6
Medium
Which type of asexual reproduction involves the organism breaking into pieces that regenerate into new individuals?
A.
Budding
B.
Binary fission
C.
Fragmentation
D.
Parthenogenesis
Show Answer & Explanation
Correct Answer: C
Fragmentation is the process where an organism breaks into pieces, and each piece can regenerate into a new individual, unlike the other types of asexual reproduction listed.
Q7
Medium
A unicellular organism reproduces by binary fission. If the organism divides every 30 minutes, how many organisms will there be after 3 hours?
A.
8
B.
64
C.
16
D.
32
Show Answer & Explanation
Correct Answer: B
After 3 hours (180 minutes), the organism will have undergone 6 divisions (since 180/30 = 6). The number of organisms after n fissions is given by 2^n. Thus, 2^6 = 64.
Q8
Hard
Which of the following statements about binary fission in prokaryotes is NOT true?
A.
It results in two genetically identical cells.
B.
It involves the replication of nuclear material.
C.
It is a form of asexual reproduction.
D.
It occurs in bacteria and some protozoans.
Show Answer & Explanation
Correct Answer: B
Binary fission does not involve the replication of nuclear material, as prokaryotes lack a true nucleus. The DNA simply replicates and divides without the formation of mitotic structures.
Q9
Hard
In which of the following organisms does fragmentation as a mode of asexual reproduction mainly occur?
A.
Planaria
B.
Mushrooms
C.
Hydra
D.
Yeast
Show Answer & Explanation
Correct Answer: A
Fragmentation is a form of asexual reproduction seen primarily in organisms like Planaria, where the body fragments and each piece can develop into a new individual.
Q10
Hard
A species of starfish is known to reproduce asexually through a method involving regeneration. Which of the following best describes this process?
A.
Budding
B.
Fission
C.
Regeneration
D.
Parthenogenesis
Show Answer & Explanation
Correct Answer: C
Regeneration is the process by which certain organisms, like starfish, can regrow lost parts and can also reproduce asexually by forming new individuals from their body parts.
