D3.1 Flashcards
Compare sexual and asexual life cycles.
Outline the roles of meiosis and fertilization in the sexual life cycle.
State that meiosis and fertilization produce individuals with new combinations of genetic material.
Compare motility, size, energy reserves and production rate of male and female gametes of plants and animals.
Draw a diagram of the male reproductive system, including the penis (with erectile tissue), urethra, testis, scrotum, epididymis, sperm duct, prostate gland and seminal vesicle.
Outline the function of the following male reproductive structures: testis, scrotum, epididymis, sperm duct, seminal vesicle, prostate gland, urethra and penis.
Draw a diagram of the female reproductive system, including the ovary, uterus, vulva, vagina, cervix and oviduct.
Outline the function of the following female reproductive structures: ovary, uterus, vulva, vagina, cervix and oviduct.
Define ovarian cycle, uterine cycle and menstrual cycle.
State the source and location of action of hormones in the ovarian cycle, including FSH (follicle stimulating hormone), LH (luteinizing hormone), estrogen and progesterone.
Describe the negative feedback loop that regulates secretion of FSH during the ovarian cycle.
Describe the positive feedback loop that regulates secretion of LH during the ovarian cycle.
Outline events occurring during the uterine cycle.
Annotate a graph showing hormone levels of the menstrual cycle, illustrating the relationship between changes in hormone levels and follicular development, ovulation, changes to the corpus luteum, menstruation and the thickening of the endometrium.
Describe the process of fertilization in humans.
Compare in vivo and in vitro fertilization.
Outline the process of medically assisted reproduction using IVF.
Outline the process of medically assisted reproduction using IVF.
Outline the roles of FSH, oestradiol and progesterone in medically assisted reproduction using IVF.
Outline the lifecycle stages of flowering plants.
Identify the location of gametogenesis in flowers.
Contrast pollination and fertilization.
Draw and label an insect pollinated flower, including: petals, sepals, stamen, anthers, filaments, pollen, carpel, stigma, style, ovary and ovule.
State the function of the different parts of the animal-pollinated flower.
Outline structures of insect-pollinated flowers that aid in the attraction of insects and transfer of pollen between flowers.
Outline the reason for homologous structures in flowers.
Define cross-pollination.
Outline the benefits of cross-pollination and self-incompatibility in flowering plants.
List methods for promoting cross-pollination in flowering plants.
Outline why self-pollination is generally avoided, even in hermaphroditic plants.
Outline the mechanism that promotes self-incompatibility in flowering plants.
Distinguish seed dispersal from pollination.
State the function of a seed.
List mechanisms of seed dispersal.
Define germination.
Outline why water, oxygen and warmth are required for germination.
Outline the role of gibberellin during germination.
Define puberty.
Explain the control of puberty by GnRH and the hormones LH and FSH.
Describe the changes of puberty in males and females that result from the hormones oestradiol, progesterone and testosterone.
State that gametogenesis involves mitosis, cell growth, two divisions of meiosis and differentiation.
Define oogenesis and spermatogenesis.
Compare the processes of spermatogenesis and oogenesis, including the number of gametes, size of games, the timing of formation and release of gametes.
Define polyspermy.
State why polyspermy is detrimental to an organism.
Explain the acrosome reaction and the cortical reaction as mechanisms that prevent polyspermy.
Define zygote, blastocyst, embryo and fetus.
Outline embryonic development from zygote to blastocyst.
Draw a diagram of a blastocyst, labeling the inner cell mass.
Outline the process of implantation of a blastocyst into the endometrium.
List the source, target and function of human chorionic gonadotropin (hCG) as related to the maintenance of pregnancy.
Define “monoclonal antibody.”
Describe how a pregnancy test strip works, including the role of free and immobilized monoclonal antibodies.
State the function of the placenta.
Explain the benefits of having a high chorion surface area and a selectively permeable placental barrier.
List the direction and mechanism of transport between maternal and fetal blood in the placenta for CO2, O2, glucose, amino acids, lipids, antibodies and water.
List the source, target and function of progesterone as related to maintaining pregnancy.
List the source, target and function of oxytocin as related to the childbirth process.
Outline the role of positive feedback in childbirth.
Discuss the use of hormone replacement therapy in postmenopausal women.
Evaluate the relationship between HRT and incidence of coronary heart disease.
