Sexual vs Asexual Reproduction Flashcards
What is asexual reproduction?
Asexual reproduction is a mode of reproduction where offspring are produced from a single parent without the involvement of gametes.
Give an example of an organism that reproduces asexually.
Bacteria, such as E. coli, reproduce asexually through binary fission.
True or False: Asexual reproduction results in genetically identical offspring.
True
What is sexual reproduction?
Sexual reproduction is a mode of reproduction that involves the fusion of male and female gametes, resulting in genetically diverse offspring.
Fill in the blank: In sexual reproduction, the male gamete is called a ______.
sperm
What is the female gamete in sexual reproduction?
Egg or ovum
Name one advantage of asexual reproduction.
It allows for rapid population growth since only one parent is needed.
What is budding in asexual reproduction?
Budding is a form of asexual reproduction where a new organism develops from an outgrowth or bud on the parent organism.
Which method of reproduction typically leads to greater genetic diversity?
Sexual reproduction
True or False: Asexual reproduction can occur in multicellular organisms.
True
What is fragmentation in the context of asexual reproduction?
Fragmentation is a form of asexual reproduction where an organism breaks into fragments, each of which can develop into a new organism.
Provide an example of a plant that reproduces asexually.
Strawberries can reproduce asexually through runners.
What is parthenogenesis?
Parthenogenesis is a form of asexual reproduction where an egg develops into a new individual without being fertilized.
Fill in the blank: In sexual reproduction, the combination of genetic material from two parents increases ______.
genetic diversity
What is an advantage of sexual reproduction?
It promotes genetic variation, which can enhance survival in changing environments.
True or False: All organisms can reproduce both sexually and asexually.
False
What is a zygote?
A zygote is the fertilized egg that results from the fusion of male and female gametes.
Name a type of organism that undergoes external fertilization.
Many fish and amphibians undergo external fertilization.
Fill in the blank: Asexual reproduction is generally faster than ______.
sexual reproduction
What is the primary disadvantage of asexual reproduction?
It lacks genetic diversity, making populations more vulnerable to disease and environmental changes.
Name a process by which some plants can reproduce asexually.
Vegetative propagation
True or False: Sexual reproduction requires two parents.
True
What is the role of pollination in sexual reproduction?
Pollination facilitates the transfer of pollen from male anthers to female stigmas, allowing fertilization to occur.
What is the difference between self-fertilization and cross-fertilization?
Self-fertilization occurs when an organism fertilizes its own eggs, while cross-fertilization involves the fusion of gametes from different individuals.
Fill in the blank: In asexual reproduction, offspring are produced by ______ division.
mitotic
What is a clone?
A clone is an organism that is genetically identical to its parent, typically produced through asexual reproduction.
