differences between cancer cells and normal cell. Some of the differences are well known ‚where as others have only been recently discovered and are less well understood.You may be interested in how cancer cells are different as you are coping with your own cancer or of a loved one. For many researchers understanding how does cancer cells function differently from normal cells foundation for developing treatments designed to rid the body of cancer cells without damaging normal cells.

Impact of Technology on Cell Theory Technology has had a profound impact on the development of cell theory‚ allowing scientists to view the components of organisms on an unprecedentedly small scale. Before the creation of microscopes‚ misconceptions about how organisms were originated arose. The idea of spontaneous generation‚ a theory held for nearly two millennia‚ proposed that organisms originated from inorganic matter. The lack of technology impeded on the development of cell theory‚ until the creation

History of the Cell Theory Ryan Strehlein Cells‚ the make-up of all living things. Some cell are complete organisms‚ such as unicellular bacteria and protozoa. Other types of cells are called multicellular‚ such as nerve cells and muscle cells. Withen the cell is genetic material‚ Deoxyribonucleic Acid (DNA) containing coded instructions for the behavior and reproduction of the cell. The cell was first discovered by the 1665 English scientist Robert Hooke‚ who studied the dead cells of cork with

Site Plan | I. Neurons/nerve cells A neuron is a cell specialized to conduct electrochemical impulses called nerve impulses or action potentials. Neuron is the main cellular component of the nervous system‚ a specialized type of cell that integrates electrochemical activity of the other neurons that are connected to it and that propagates that integrated activity to other neurons. They are the basic information processing structures in the CNS.

Bacterial cells are Prokaryotic cells. These cells have several internal structures and surface structures. The cell walls are of two types‚ gram positive and gram negative. Out of all the structures‚ the two selected structures are the cell- wall and endospores. The cell- wall of bacterial cells is found in three distinct shapes such as spherical‚ spiral and rod shaped. The cell wall of the bacterial cells is composed of the proteins and polysaccharides. This is collectively called peptidoglycan

characteristics of a healthy cell and a cancer cell is very different. Healthy cells stop reproducing when there are enough cells‚ however‚ cancer cells continue to reproduce. Due to this continued growth a tumor‚ which is a cluster of cancer cells‚ is formed. Cancer cells do not interact with other cells like the healthy cells. Healthy cells stop growing when they hear signals from the nearby cells‚ in contrast‚ cancer cells do not respond to these signals. When healthy cells get old or damaged they

Abstract: The question of the investigation is if lectin can induce mitosis in the cell of an onion root tip. The hypothesis is that‚ if the lectin does not induce mitosis‚ then there should not be a great change in the number of cells that undergo mitosis. The alternate is‚ if the lectin does induce mitosis‚ then there should be an increase in of cells in mitosis. The control group of the experiment had root tip treated with water‚ and the experimental had root tip treated with lectin. Upon the
