Sep. 21‚ 2014 Stem Cells Stem cells are the beginning of organism creation and have the potential to separate‚ becoming any kind of organism‚ endlessly. These cells have not gone through the process known as differentiation‚ which gives the cell a specific function. Technically‚ due to research over the recent years‚ scientists could grow certain organs with through stem cells because of the fact that these cells can be manipulated early on. There are multiple stem cells that have been determined

Stem cells are unique because they have the ability to generate new cells of any kind during early life and growth. There are about 200 different types of cells in the body; such as muscle‚ skin and brain cells. Most of these cells have to be repaired or replaced once in a while. For example our taste buds are replaced every 10 days‚ skin cells every couple of weeks and liver cells every 300-500 days. Stem cells serve as an internal repair system dividing essentially without limit to replenish

treatment of many diseases. Stem cell research has provided hope and has brought optimism among the scientists and doctors in curing the patients who suffered or died due to the once called "untreatable" diseases decades ago. Stem cells are the ones which can develop into any type of a body cell including the cells of blood‚ liver‚ brain‚ muscles‚ and many more. They are found in adult bone marrow‚ embryos‚ fetuses‚ and blood from the umbilical cord (Bailey 100). Stem cell research is the latest advancement

roles of mitotic cell division‚ meiosis‚ and fertilization in the human life cycle. Mitosis allows for growth and repair from the fertilized egg to the adult. In reproductively mature individuals‚ meiosis creates gametes with half the genetic material. The male gamete then fertilizes the female gamete during sexual reproduction‚ forming a zygote with a full set of genetic material. 2. Why are both cell division and apoptosis necessary for the development of an organism? Cell division is needed

1.A) Two main forms of cells exist: eukaryotic cells and prokaryotic cells. Prokaryotic cells are smaller and do not have membrane-bound nucleus or membrane- bound organelles‚ but do have: plasma membrane‚ cytosol and cytoplasm‚ and ribosomes. Prokaryotes contain much less DNA than eukaryotes and have circular chromosomes. Eukaryotic cells have information processing organelles‚ such as the nucleus which houses most of the cell’s DNA‚ and ribosomes which use information from DNA to produce proteins

physical development is (more or less) complete However‚ Dr Montessori said that the new born child is psychologically still in an embryonic state – his inner development is incomplete. For this reason‚ she said that the human being is a ‘spiritual embryo’ when he is born. After birth‚ the child’s task is to create him/herself. The child does this through his interactions with his environment‚ and therefore‚ we must provide the child with an environment which is carefully prepared for and suited
