ASEXUAL REPRODUCTION Asexual reproduction is a mode of reproduction by which offspring arise from a single parent‚ and inherit the genes of that parent only; it is reproduction which does not involve meiosis‚ ploidy reduction‚ or fertilization. The offspring will be exact genetic copies of the parent. A more stringent definition is agamogenesis which is reproduction without the fusion of gametes. Asexual reproduction is the primary form of reproduction for single-celled organisms such as the archaea

Reproduction in humans Reproduction Reproduction is a characteristic of all living organisms. It is the process that makes more of the same kind of organism. Reproduction is essential in all species to ensure that the species does not extinct. There are two types of reproduction‚ Asexual and sexual reproduction. Asexual Reproduction: Asexual means not sexual. This means that this kind of reproduction does not involve sex. Asexual reproduction is the production of genetically identical offspring from

Gametes are sex cells. Fertilisation is when half the genetic material comes from male gamete and half come from female gamete and they fuse together to form a zygote. Zygote is a fertilized egg. Embryo is a divided zygote. Binary Fission in Bacteria Bacteria are microscopic organisms made up of one cell and they do not have a nucleus but a loop of DNA. When bacteria‚ reproduce asexually the DNA loop is copied so that there is some for each new cell. The bacterial cell deivides into two by

Vegetative reproduction (vegetative propagation‚ vegetative multiplication‚ vegetative cloning) is a form of asexual reproduction in plants. It is a process by which new individuals arise without production of seeds or spores. It can occur naturally or be induced by horticulturists. Although most plants normally reproduce sexually‚ many have the ability for vegetative propagation‚ or can be vegetatively propagated if small pieces are subjected to chemical (hormonal) treatments. This is because meristematic

Bourgeoisie from the Proletariat. As Walter Benjamin defines it – it was mechanical reproduction of artwork that the capitalists in power and laymen alike were able to experience without the limitations of financial shortcomings for either class. In this essay I will discuss this concept in light of Benjamin’s famous piece entitled “The Work of Art in the Age of Mechanical Reproduction.” Mechanical reproduction allows for us to easily reproduce artwork in different forms. However‚ this process

The main connection between the Terran and the Tlic is the birthing process. The Tlic use the Terran to carry their grubs for them‚ because the Tlic are not able to carry their children themselves. The author uses her story to examine and explore reproduction rights that were being debated or taking place during the time she was writing. Some examples of these rights are exhibited in the incidents of abortion‚ rape‚ and surrogate parenthood. These issues that are present in the story are important because

Plants have two different ways to reproduce. The first one is vegetative reproduction. With this type all the plants that have the same parent have the same genetic make-up. This also lets plants pass adaptations on that they have abtained over the years. Plants with good genetic make-up usually spread quickly and take over an area. An example of this would be the dandelion. These plants can sprout from any part of the plant. An example of this is the potato‚ farmers will pick the potatoes and cut

Definitions In relation to the topic‚ MacLeod explains social reproduction as the theory that “explains how societal institutions perpetuate or reproduce the social relationships and attitudes needed to sustain the existing relations of production in a capitalist society.” (MacLeod 9) In this definition‚ the societal institutions are places like‚ government offices‚ and schools. These institutions according to him help continue to maintain the status quo by preserving the existing barriers between

Developmental anatomy is concerned with the changes that cells‚ tissues‚ organs and the body as a whole undergo from germ cells to the adult. Teratology (teratos=monester) is the division of embryology that deals with birth defects.. TERMINOLOGY Oocyte (ovum‚ egg) is the female germ or sex cell produced in the ovaries. Sperm (seed)‚ Spermatozoon (zoon=animal) is the male germ cell produced in the testes. Zygote (union) is the cell
