What type of cell division produces sperm and egg cells?

Back

Meiosis produces sperm and egg cells, maintaining the haploid number of chromosomes necessary for fertilization.

Front

What type of reproduction do humans use?

Back

Humans reproduce via sexual reproduction.

Front

What characterizes asexual reproduction?

Back

Asexual reproduction is characterized by one parent and genetically identical offspring.

Front

What is ovulation?

Back

Ovulation is the release of an egg from an ovary.

Front

What substances does the placenta transport between mother and fetus?

Back

The placenta transports nutrients and oxygen from the mother to the fetus and removes wastes and carbon dioxide from the fetus's blood.

Front

What is the role of meiosis in human reproduction?

Back

Meiosis reduces the chromosome number by half, producing haploid gametes (sperm and egg) for fertilization.

Front

Define fertilization in human reproduction.

Back

Fertilization is the process where a sperm cell joins with an egg cell to form a zygote.

Front

What is the function of the umbilical cord?

Back

The umbilical cord connects the fetus to the placenta, allowing for nutrient and waste exchange.

Front

What is the difference between haploid and diploid cells?

Back

Haploid cells have one set of chromosomes (n), while diploid cells have two sets (2n).

Front

What is the significance of the zygote being diploid?

Back

The diploid zygote contains the full set of chromosomes, restoring the species' chromosome number after fertilization.
