Grade 12 Questions and Answers Human Reproduction
Below are the key topics covered in the Human Reproduction Grade 12 CAPS South African Exam:
Anatomy of the Male and Female Reproductive Systems This section covers the structure and function of the male and female reproductive organs, including gamete production and transport. Students will also learn about the hormonal regulation of the male and female reproductive systems.
Fertilization and Early Development This section covers the process of fertilization and the formation and implantation of the embryo. Students will also learn about the different stages of prenatal development.
Menstrual Cycle and Pregnancy This section covers the phases of the menstrual cycle and the hormonal regulation of the menstrual cycle. Students will also learn about the stages of pregnancy and fetal development.
Sexually Transmitted Infections (STIs) This section covers the causes and symptoms of common STIs, as well as their prevention and treatment.
Contraception and Family Planning This section covers the different types of contraception and the advantages and disadvantages of each method. Students will also learn about the principles of family planning and reproductive health.
To excel in the Human Reproduction Grade 12 exam in South Africa, it is essential to have a solid grasp of each section mentioned above. In addition to studying the material, practicing questions and reviewing past papers can be beneficial in preparing for the exam.
Grade 12 Questions and Answers Human Reproduction
The following are grade 12 human reproduction questions and answers that can aid in better understanding the topic:
- What is the role of the hypothalamus in the female reproductive system?
Answer: The hypothalamus is responsible for producing gonadotropin-releasing hormone (GnRH) in the female reproductive system, which stimulates the pituitary gland to produce follicle-stimulating hormone (FSH) and luteinizing hormone (LH). These hormones regulate the menstrual cycle and prepare the ovaries for pregnancy by triggering the production of estrogen and progesterone.
- What is the difference between mitosis and meiosis?
Answer: Mitosis is the process of cell division that produces two identical daughter cells with the same number of chromosomes as the parent cell, while meiosis is the process that creates four genetically diverse daughter cells with half the number of chromosomes as the parent cell. Meiosis is used in the formation of gametes (sperm and eggs) for sexual reproduction.
- What is the function of the prostate gland?
Answer: The prostate gland is a vital part of the male reproductive system that secretes fluid that makes up a portion of semen. This fluid supports the motility and survival of the sperm as they travel through the female reproductive system.
- What is the function of the corpus luteum?
Answer: The corpus luteum is a temporary gland that develops in the ovary after ovulation. Its primary function is to produce progesterone, which thickens the endometrial lining of the uterus and inhibits uterine contractions to prepare for pregnancy.
- What is the process of fertilization?
Answer: Fertilization is the fusion of a sperm cell and an egg cell to create a single cell called a zygote. This process usually takes place in the fallopian tube, where the sperm and egg meet. The sperm must first penetrate the egg’s outer layer and then the egg’s membrane to reach the nucleus and combine with the egg’s genetic material. Once fertilization happens, the zygote divides and develops into an embryo. Practice with these questions and answers can improve the understanding and knowledge of human reproduction.
