Reproduction

Flowers, produce by the sporophyte, function in sexual reproduction The four floral organs are sepals, petals, stamens, and carpel. Sepals protect the floral bud. Petals help attract pollinators. Stamens bear anthers in which haploid microspores develop into pollen grains containing male gametophytes. Carpel contains ovules (immature seeds) in their swollen bases. Within the ovules, embryos sacs (female’s gametophytes) develop from megaspore. Pollination which precedes fertilization is the…

When looking at the data provided, the trends of native-species increase in the restored area and the abundance of exotic species seen in the degraded areas provides an idea of how effective the restoration efforts where at restoring them to the reference site. To begin, the data provided in table 5 gives an idea of the distribution of the number of species found at each site, and how much of a contrast is shown between the restored and degraded areas and how they compare to the reference site.…

Photosynthesis and sexual reproduction are the two main turning points in the history of life, because the ability to process energy from sunlight, random variation and non-random selection allowed for evolutionary growth and the survival of life. Photosynthesis, an important process of energy transformation is crucial in the development of metabolic microorganisms, as well as the evolutionary changes from primitive to more complex life. Sexual reproduction displays a significant evolutionary…

conceiving a child and giving birth. Infertility as well as rising prevalence of homosexual couples in the eyes of the fields of medicine has lead to the development of methods of assisted reproduction, one method being that of In Vitro Fertilization. In Vitro Fertilization, or IVF, has become a method of assisted reproduction highly recommended by physicians for infertile or homosexual couples. IVF, as it is related to the beginning of a life of a human, the health of the mother, and the family…

In the video, Dr. Scott Rae is making the comparison of using medical technology in the assist of procreation and using medical technology with the everyday usage of human’s bodily organs. He used the example of having medical technology assist people with kidney failure or with lung failure. The comparison is made when there is assistance with medical technology and procreation. To be honest, I have never thought of it that way. If there is a blockage in the fallopian tube, then why can’t…

mainly helps us produces the female egg cells necessary for reproduction, called the ova or oocytes. The reproductive system is very important part of the body system because it helps the population to reproduce, it is a very crucial factor of living.The reproductive system helps our body to produce new cells. One of the most widespread diseases of the reproductive system is known as prostate cancer that only affects the reproduction cells. Prostate cancer mostly happens when the cells in the…

Advances in technology related to genetic mapping and embryonic screening have raised several ethical dilemmas regarding the morality of parents choosing children based on certain characteristics. Screening for disability and sex is already occurring, and screening for other characteristics is not out of the question in the near future. The idea of “designer babies” is morally questionable for many people worried about “playing God” or causing problems at a broader, societal level. Based on the…

article delves into the help and hindrance of men. From Ridley’s perspective, males are useless as he further supports his claim “quote”. Key principles as stated in the article include man’s drive to execute violent crimes, poor pedigree, irrelevant reproduction value, and desire to fulfill an alpha role which promotes the previous assertions. Therefore, women exude superior qualities of the human race compared to men. Ridley argues why he believes males…

Understanding our present has much to do with first knowing of our past. In this essay I will be discussing how sex and biological reproduction impacted the division of labor and the origins of gender roles in early male and female hominids and Homo sapiens. I will also address how the advancements in the technology of biological reproductive control, has affected and shaped modern day gender roles. The major drive for early hominids and Homo sapiens was the acquisition of food and reproductive…

Rifkin’s article “Evolution’s Pregnant Pause: Artificial Wombs,” appeared in the Los Angeles Times in 2002, it successfully ask the question is artificial wombs waging a war against natural childbirth and women? This war has worried me because its purpose is to undermine the medical benefits of this technology. Traditionally women give birth, in which women are the principal caregivers of the children. Reading, Rifkin’s article he questions the parental responsibility and the role of women. The…
