Biology- Animal cell The NUCLEUS is the largest organelle in the majority of cells. It contains genetic information in DNA‚ which is responsible for the cells unique characteristics. The nucleus is separated from the rest of the cell by.... ...The NUCLEAR ENVELOPE is used as a barrier which separates the contents of the nucleus from the cytoplasm‚ all in all keeping the DNA safe and intact. The nuclear envelope regulates the flow of substances into and out of the nucleus. The NUCLEOLUS is an important

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

Henrietta’s Cells. It is unfortunate that the Lacks family did not know that research was being done on Henrietta’s cells‚ which made the family feel like they were betrayed by doctors at the Johns Hopkins Hospital‚ but it was a common practice of doctors in the 1950s and consent was not required for research as it is today. Also‚ it is unfair that Samuel Reader and Monroe Vincent‚ the founders of Microbiological associates‚ a cell distribution company‚ made millions off of selling HeLa cells. However

Eukaryotes are organisms whose cells are organized into complex structures by internal membranes and a cytoskeleton. The most characteristic membrane bound structure is the nucleus. This feature gives them their name‚ (also spelled "eucaryote‚") which comes from the Greek word referring to the nucleus. Animals‚ plants‚ fungi‚ and protists are eukaryotes. Microorganisms and all other living organisms are classified as prokaryotes or eukaryotes. Prokaryotes and eukaryotes are distinguished on the

Prokaryotic Cell Structure Bacterial Cell Structure Mariana Ruiz Villarreal/Wikimedia Commons Prokaryotes are single-celled organisms that are the earliest and most primitive forms of life on earth. As organized in the Three Domain System‚ prokaryotes include bacteria and archaeans. Prokaryotes are able to live and thrive in various types of environments including extreme habitats such as hydrothermal vents‚ hot springs‚ swamps‚ wetlands‚ and the guts of animals.

Cells do everything from providing structure and stability to providing energy and a means of reproduction for an organism. There are many professions that have jobs like the organelles in a cell. One example is a Prison. A prison is a clear representation of a cell because all the organelles have a function that is tantamount to a prison. Also it is logical because each function have a function that relates to the jobs found in a prison. The Nucleus in a cell controls everything in the cell
