possible‚ that cancer cells have the same characteristics as normal stem cells and that is why they grow and invade rapidly? And if so can scientist and doctors use this information to find a permanent cure or a better way to stop cancer? The vague knowledge about how cancer is formed is that our healthy genes are suddenly mutated. They are most likely mutated during a process called mitosis. Mitosis is apart of the cell life cycle.

microscopic objects such as cells. The first to accomplish this was Robert Hooke when he used a light microscope to observe a thin slice of cork. Hooke observed that the cork was made of tiny structures of which he called cells. Hooke was in fact looking at the cell walls of dead plant cells that make up the cork. After Hooke‚ a Dutch scientist named Anton van Leeuwenhoek used the light microscope to observe living cells inside stagnant rain water. This then developed the cell theory in which all living

have a huge impact on the communication between cells. Cell communication is a crucial process necessary for cells to carry out various functions. Drugs such as Methylenedioxymethamphetamine (MDMA)‚ known as ecstasy‚ can create barriers or confusion to cells. Cell to cell communication carry messages from signaling cells to target cells. Usually a cell will bind with a target cell through a receptor protein in the plasma membrane of the target cell

The cell is the fundamental structural unit of all living organisms. Some cells are complete organisms‚ such as the unicellular bacteria and protozoa; others‚ such as nerve‚ liver‚ and muscle cells‚ are specialized components of multi-cellular organisms. Cells range in size from the smallest bacteria-like mycoplasmas‚ which are 0.1 micrometer in diameter‚ to the egg yolks of ostriches‚ which are about 8 cm (about 3 in) in diameter. Although they may differ widely in appearance and function‚ all cells

Prokaryotes were the only form of life on Earth for millions of years until more complicated eukaryotic cells came into being through the process of evolution.
