Reproduction Flashcards
(25 cards)
What is sexual reproduction?
A biological process that involves the fusion of male and female gametes to form a new organism.
True or False: Sexual reproduction results in offspring that are genetically identical to the parents.
False
Fill in the blank: In sexual reproduction, the male gamete is called a _____ and the female gamete is called an _____.
sperm; egg
What are the two main types of gametes involved in sexual reproduction?
Sperm and egg.
Multiple Choice: Which of the following is NOT a benefit of sexual reproduction? A) Genetic diversity B) Faster population growth C) Adaptation to changing environments D) Increased survival of species
B) Faster population growth
What is fertilization in the context of sexual reproduction?
The process where a sperm cell merges with an egg cell to create a zygote.
True or False: Sexual reproduction occurs only in animals.
False
What is a zygote?
The initial cell formed when a sperm fertilizes an egg.
Fill in the blank: The offspring produced by sexual reproduction inherit _____ from both parents.
genetic material
Multiple Choice: Which of the following organisms primarily reproduce sexually? A) Bacteria B) Fungi C) Mammals D) Viruses
C) Mammals
What role does meiosis play in sexual reproduction?
Meiosis is the process that produces gametes with half the number of chromosomes.
True or False: Sexual reproduction can lead to greater genetic variation compared to asexual reproduction.
True
What is external fertilization?
A process where fertilization occurs outside the female’s body, common in aquatic animals.
Fill in the blank: Sexual reproduction typically involves two parents, resulting in _____ offspring.
genetically diverse
What is internal fertilization?
A process where fertilization occurs inside the female’s body, common in terrestrial animals.
Multiple Choice: Which of the following is a disadvantage of sexual reproduction? A) Requires more time B) Produces genetically diverse offspring C) Involves complex mating behaviors D) All of the above
D) All of the above
What term describes the genetic makeup of an organism?
Genotype
True or False: Sexual reproduction is the only method of reproduction in nature.
False
What is the significance of genetic recombination during sexual reproduction?
It increases genetic diversity in the population.
Fill in the blank: The male reproductive system produces _____, while the female reproductive system produces _____.
sperm; eggs
What is asexual reproduction?
A form of reproduction that does not involve the fusion of gametes and results in genetically identical offspring.
Multiple Choice: Which of the following is a method of sexual reproduction? A) Budding B) Binary fission C) Pollination D) Fragmentation
C) Pollination
What is the term for the observable characteristics of an organism?
Phenotype
True or False: Sexual reproduction can occur in both plants and animals.
True
