Answer the following questions on Sexual Reproduction in Humans IGCSE. Read the question carefully and write a detailed answer.
How does sexual reproduction differ from asexual reproduction?
What are the primary male and female sex organs?
How does the release of hormones regulate the menstrual cycle?
What is the process by which sperm is produced?
What is the role of fertilization in sexual reproduction?
Each question is worth 20 points
Sexual reproduction requires the combination of genetic material from two parents, while asexual reproduction does not involve the combination of genetic material from two parents. In sexual reproduction, offspring are genetically diverse, while offspring in asexual reproduction are genetically identical to the parent.
The primary male sex organs are the testes, which produce sperm. The primary female sex organs are the ovaries, which produce eggs.
Hormones released from the hypothalamus, pituitary gland, and ovaries control the menstrual cycle. FSH (follicle-stimulating hormone) stimulates the growth of follicles in the ovaries, which produce estrogen. When estrogen levels are high, LH (luteinizing hormone) is released, which causes ovulation. If fertilization does not occur, progesterone levels decrease, and the menstrual cycle begins again.
Sperm is produced through the process of spermatogenesis, which occurs in the seminiferous tubules of the testes. Spermatogenesis involves the division of diploid cells into haploid cells through meiosis.
Fertilization is the process by which sperm and egg combine to form a zygote. During fertilization, the haploid sperm fuses with the haploid egg, forming a diploid zygote. The zygote contains genetic material from both parents and is the first cell of the developing embryo.
