    that we know today. This is the 3 domain system proposed by Carl Woese. This system suggests that there are three forms of life. The Prokaryotes, Eukaryotes and the Archaea. Some research has been conducted that suggests the Eukaryotes formed from a cell fusion between an Archaea and a Prokaryote. This theory explains how the Eukaryotes become such a specialised life form. They were able to incorporate features from both Archaea and Prokaryotes. However, there are some missing pieces of information

    contain cells which are arranged into complex structures by internal membranes and a cytoskeleton. Eukaryotic cells have membrane-bound nucleus and many membrane-enclosed organelles such as the endoplasmic reticulum, mitochondria, lysosomes and Golgi apparatus, which are not found in prokaryotic cells. Most prokaryotes are unicellular, but some are multicellular. Life on earth is classified into five kingdoms based on what an organism's cells are like. The main division is between cells of the

    astronomer, invented the new machine called Archimedes’ screw with combining all of his knowledge. Like you can see, cities and machines are related. Some big cities were made by machine, and some machines were made because of the cities. Then, is the cell more like machine or city? To start, we need to discuss about similarities and differences between those two. What is the city? There are many different definitions of city and many people have different opinions about it and it is still very controversial

    Cancer Institute in Bethesda. He writes about genome cell biology, and its many early questions and theories that only recently could be answered due to the development of 3D imaging, and chromosome marking technologies. Chromosome markers have allowed for observations to be made into the genomes complex spaghetti like structure. It has been observed that in different cell types the chromosome position change, chromosomes on the periphery of the nucleus were more likely to become inactive, while the chromosomes

    THESIs: Cells Unit Cells are the basic unit of line. The purpose of learning about cells is to become educated on how living things work and what are needed to keep them healthy. Cells were learned about slowly and studied by many people. Cells are different based on what they have to support. Photosynthesis and cellular respiration are directly related. The cell cycle is how cells change and divide. Plants have many different cells and tissues that are for their own benefit. Cells are the

    organism develops from only one parent. The one process of cloning, called nuclear transfer, replaces the nucleus of an immature egg with a nucleus from another cell. Most of the work with clones is done from cultures. An embryo has about thirty or forty usable cells but a culture features an almost endless supply. When the nucleus has been inserted into the egg cell, the cell is given an electric shock to initiate the development. Traditionally this is the sperm?s role. In this

    One of the biggest changes between prokaryotic and eukaryotic cells is the fact that instead of only one intracellular space they are now divided and has membrane bound organelles. Why would eukaryotic cells go through all the difficulty to become compartmentalised? It obviously must have held some advantages which outweighed the trouble. In this essay the advantages and resulting problems of specialised compartments in eukaryotic cells will be discussed. First we will look at the advantages gained
