#1
Which organ in the male reproductive system produces sperm cells?
Testes
ExplanationTestes produce sperm cells through spermatogenesis.
#2
What is the main function of the fallopian tubes?
Fertilization of the egg
ExplanationFallopian tubes are where fertilization typically occurs, as they transport the egg to the uterus.
#3
What is the name of the structure where spermatogenesis occurs in the testes?
Seminiferous tubules
ExplanationSeminiferous tubules are structures within the testes where spermatogenesis takes place.
#4
Which hormone is responsible for the development of secondary sexual characteristics in males?
Testosterone
ExplanationTestosterone is the primary male sex hormone responsible for the development of secondary sexual characteristics.
#5
What is the function of the prostate gland?
Production of seminal fluid
ExplanationThe prostate gland produces seminal fluid, a component of semen.
#6
Which structure connects the ovaries to the uterus?
Fallopian tube
ExplanationThe fallopian tubes connect the ovaries to the uterus, facilitating the transport of eggs.
#7
Which phase of meiosis involves crossing over of genetic material?
Prophase I
ExplanationCrossing over of genetic material occurs during Prophase I, promoting genetic diversity.
#8
What is the name of the process where a sperm penetrates an egg?
Fertilization
ExplanationFertilization is the process of sperm penetrating an egg, initiating the formation of a zygote.
#9
During which phase of meiosis does chromosome number get halved?
Anaphase I
ExplanationChromosome number is halved during Anaphase I as homologous chromosomes separate.
#10
What is the term for the shedding of the uterine lining during the menstrual cycle?
Menstruation
ExplanationMenstruation is the shedding of the uterine lining, occurring if implantation does not occur.
#11
During which phase of meiosis does homologous chromosome pairing occur?
Prophase I
ExplanationHomologous chromosome pairing occurs during Prophase I, leading to genetic recombination.
#12
What is the term for the release of an egg from the ovary?
Ovulation
ExplanationOvulation is the release of an egg from the ovary, typically occurring midway through the menstrual cycle.
#13
Which of the following cells is produced by meiosis?
Gametes
ExplanationMeiosis produces gametes, which are reproductive cells with half the chromosome number of somatic cells.
#14
Which of the following is a feature of meiosis but not mitosis?
Produces haploid cells
ExplanationMeiosis produces haploid cells with half the chromosome number, unlike mitosis which produces diploid cells.
#15
Which event occurs during telophase II of meiosis?
Division of the cytoplasm
ExplanationTelophase II involves the division of the cytoplasm, resulting in the formation of four haploid daughter cells.
#16
Which of the following events occurs during prophase II of meiosis?
Nuclear envelope breakdown
ExplanationProphase II involves the breakdown of the nuclear envelope, allowing spindle fibers to access the chromosomes.
#17
Which of the following is a characteristic of anaphase II of meiosis?
Separation of sister chromatids
ExplanationAnaphase II involves the separation of sister chromatids, resulting in the formation of haploid daughter cells.
