Gamete 4.2 Flashcards
What are gametes?
Gametes are reproductive cells that unite during sexual reproduction to form a new organism.
True or False: Gametes are diploid cells.
False. Gametes are haploid cells.
What type of gamete do males produce?
Males produce sperm gametes.
What type of gamete do females produce?
Females produce egg (or ovum) gametes.
Fill in the blank: The process of gamete formation is called _______.
gametogenesis.
What is the significance of meiosis in gamete formation?
Meiosis reduces the chromosome number by half, producing haploid gametes.
Multiple Choice: Which of the following is NOT a function of gametes? A) Fertilization B) Genetic variation C) Growth and repair
C) Growth and repair.
True or False: Gametes contain a complete set of chromosomes.
False. Gametes contain half the number of chromosomes.
Short Answer: What is the genetic contribution of each parent to the offspring?
Each parent contributes one haploid gamete, resulting in a diploid zygote.
What is the role of the zygote in reproduction?
The zygote is the fertilized egg that develops into a new organism.
Fill in the blank: Sperm are produced in the _______.
testes.
Fill in the blank: Eggs are produced in the _______.
ovaries.
True or False: All animals produce gametes through the same method.
False. Different species may use different methods for gamete production.
What is external fertilization?
External fertilization is when gametes unite outside the bodies of the parents.
What is internal fertilization?
Internal fertilization is when gametes unite inside the female’s body.
Multiple Choice: Which of the following organisms typically uses external fertilization? A) Mammals B) Fish C) Birds
B) Fish.
What is the main purpose of gametes in sexual reproduction?
To combine genetic material from two parents to create genetic diversity.
Fill in the blank: The fusion of sperm and egg is known as _______.
fertilization.
True or False: Gametes are produced by mitosis.
False. Gametes are produced by meiosis.
Short Answer: What is the chromosome number in human gametes?
23 chromosomes.
What is a haploid cell?
A haploid cell is a cell that contains one complete set of chromosomes.
What is a diploid cell?
A diploid cell is a cell that contains two complete sets of chromosomes.
Multiple Choice: Which process increases genetic variation in gametes? A) Mitosis B) Meiosis C) Cloning
B) Meiosis.
Fill in the blank: The male gamete is also known as the _______.
sperm.
