Professor Derek J. Thiess Rhetoric 105 29th Nov‚ 2010 Embryonic Stem Cell Research Over the last decade the use of stem cells has been a controversial and heated topic. Debates have exploded over every aspect of stem cell research in nearly every region of the world. Every aspect of stem cell research has come under debate in nearly every region of the world. It has been speculated by scientists that stem cell research may have the power to potentially cure incredibly harmful diseases or

Animal Cells Every once living thing is composed of cells. Cells are small organisms that control everything in living things. When an organism is made of one or more cells it is called a multi cellular organism. The first person to discover cells was Richard Hooke. The cells that he saw were the dead cells of cork. When he first saw them they reminded him of the cells that nearby monks lived in. there are many different parts of the cell but all serve a purpose. These many parts of the cells are

microstructure of a typical animal cell and the functions of the main cell components. A typical animal cell is seen as a tiny‚ three dimensional sac which is in fact made up of many components‚ each as important as the other. The microstructure of an animal cell was in fact uncovered mainly through the use of both cell fractionation and electron microscopy. Each main component has its own‚ individual function which helps a cell to function and maintains the cell membrane. The components that I will

In life’s hierarchy‚ cells make up the lowest level of organization. Cells can perform activities required to sustain life. A cell’s ability to divide to form new cells is the basis for growth and repair in organisms. Cells also play a key role in the recycling of carbon‚ a chemical element essential to life‚ and also participate in cellular processes such as photosynthesis. With these points in mind‚ it should be noted that cells come in one of two forms: prokaryotic and eukaryotic. By investigating

1.) Cells are complex and incredible structures that through series of reactions can create cellular energy‚ reproduce genetic material and eliminate waste products. Eukaryotic cells are more complex than prokaryotic cells and it is believed that they evolved from prokaryotes. What are 3 major characteristics that distinguish eukaryotes from prokaryotes? Choose 2 pieces of evidence (that we learned about in class) and explain how they support the theory that eukaryotes evolved from prokaryotes

CELL ULTRASTRUCTURE CELL ULTRASTRUCTURE Cells are the smallest functional units of the body‚ (Waugh‚ A. and Grant‚ A.2010). Most cells are microscopic. The largest cell in the body is the female ovum. The erythrocyte is the smallest cell. The longest cell is the neuron. Cells group together to form tissues‚ each of which has specialised function. Different tissues group together to form organs. Organs are group together to form organ systems‚ each of which performs a particular function that

Chinese Culture - The Culture of Shanghai Shanghai University 30.11.2012 Shanghai – Brief Overview Shanghai is an important commercial harbor and the most important industrial town of the People ’s Republic of China. The administrative area has more than 23 million inhabitants. The status of the town corresponds to that of a province; the town is subordinated directly of the central government. Shanghai is an important traffic interchange and an important cultural center and educational

CELL REPRODUCTION DNA is the cell’s genetic material; chromosomes are the carriers of this genetic information. In proka-ryotes‚ the chromosome is a single circle of DNA. In eukaryotes‚ each chromosome is a complex of DNA and histone proteins found in the nucleus. BINARY FISSION Prokaryotic cells reproduce via binary fission. In this process‚ DNA Is replicated‚ and the cell splits in two roughly equal parts‚ each with a copy of the cell’s DNA. EUKARYOTIC CELL CYCLE Eukaryotic cells reproduce

Stem Cell Research Stem cell research is no longer a future unrealistic concept‚ it is here and having enormous impacts on the medical field. Stem cells are the primary cells that can be trained to develop into any human cell tissue such as muscle‚ skin‚ and brain. However‚ in embryonic stem cell research‚ to retrieve stem cells from embryos requires a process called therapeutic cloning where a person’s DNA is put into an unfertilized human egg (effectively cloning a person)‚ the embryo is then
