background knowledge relating to the current cell theory‚ the differences between prokaryotes and eukaryotes‚ and the structures and functions found within cells. Once this knowledge is known‚ a person is then able to give their opinion in the debate. In the 1800s‚ the cell theory was developed. This theory states that cells are found in all living things making them the basic units of life and that all cells come from other cells. In order to be classified as a cell‚ the object in question must be able

What are microfilaments? (He said know how to identify/draw these) Note: since it is multiple choice‚ I doubt we will have to know how to draw them. **There are also short essay questions and‚ in past classes‚ he has asked students to draw. I thought the final was ALL MULTIPLE CHOICE???********************************

The CELL THEORY‚ or cell doctrine‚ states that all organisms are composed of similar units of organization‚ called cells. The concept was formally articulated in 1839 by Schleiden & Schwann and has remained as the foundation of modern biology. The idea predates other great paradigms of biology including Darwin’s theory of evolution (1859)‚ Mendel’s laws of inheritance (1865)‚ and the establishment of comparative biochemistry (1940). Ultrastructural research and modern molecular biology have

Cell wall is a fairly rigid‚ protective and supportive layer surrounding the cell external to plasma membrane of plants‚ bacteria‚ archaea‚ fungi and algae. It is absent in animals and most protists. It was first observed by Robert Hooke in 1665. It is not an entirely rigid structure as the cell wall expands due to the growth of the cell. It varies in thickness from o.1mm to I0mm.in most of the cells‚ cell wall is present from the very beginning to the last‚ but in slime molds (myxomycetes)

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

Eukaryotic Cells Worksheet Provide a list describing at least three differences between prokaryotic and eukaryotic cells: 1. While Prokaryotes contain just one copy of each gene‚ eukaryotic cells have two. For such reason‚ prokaryotes are known as haploid and eukaryotic as diploid. 2. While Prokaryotes see some nonessential genes being encoded into extra-chromosomal plasmids‚ such activity is typically absent in Eukaryotic cells. 3. The own way DNA is present in each type of cell has different

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
