biology‚ cell theory is a scientific theory that describes the properties of cells‚ which are the basic unit of structure in all organisms and also the basic unit of reproduction. The initial development of the theory‚ during the mid-17th century‚ was made possible by advances in microscopy; the study of cells is called cell biology. Cell theory is one of the foundations of biology.The observations of Hooke‚ Leeuwenhoek‚ Schleiden‚ Schwann‚ Virchow‚ and others led to the development of the cell theory

allow cell phones to be sold without pre-market testing. The rationale‚ known as the “low power exclusion‚” distinguished cell phones from dangerous microwave ovens based on the amount of power used to push the microwaves. At that time‚ the only health effect seen from microwaves involved high power strong enough to heat human tissue. The pressure worked‚ and cell phones were exempted from any type of regulatory oversight‚ an exemption that continues today. An eager public grabbed up the cell phones

though a cell is the basic unit of an organism it can be pretty complex inside of one. So why don’t we try and make it a little simpler by comparing it to something we’re all more comfortable with? Take Disneyland for example! Everyone is familiar with Disneyland and how it works. Let’s see just how similar these two can be. First‚ would be the entrance gate. The entrance gate could be our cytoplasm. Cytoplasm is the jelly-like fluid that fills a cell and inside is all the other cell organelles

PLANT CELL Introduction Plant cell is the basic unit of structure and function in nearly all plants. The range of specialization and the character of association of plant cells are very wide. In the simplest plant forms a single cell constitutes a whole organism and carries out all the life functions. In just slightly more complex forms‚ cells are associated structurally‚ but each cell appears to carry out the fundamental life functions‚ although certain ones may be specialized
