The 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

Stem Cell Research
Stem Cell Research Miguel Amador Biology 131 November 8, 2003 Stem Cell Research Stem cells are located deep down in our bone marrow. They have the incredible ability of “generating an endless supply of red cells, white cells, and platelets”(1). They have been called the “Mother of all blood cells” due to their ability to regenerate the entire blood supply of a persons body. Just to think that this is possible is actually pretty incredible.

Matthias Schleiden - Cells
Cells Discovery and Basic Structure In 1655, the English scientist Robert Hooke made an observation that would change basic biological theory and research forever. While examining a dried section of cork tree with a crude light microscope, he observed small chambers and named them cells. Within a decade, researchers had determined that cells were not empty but, instead, filled with a watery substance called cytoplasm. Over the next 1 years, research led to the formation

Detailed Differences Between Eukaryotic and Prokaryotic Cells
DETAILED DIFFERENCES BETWEEN EUKARYOTIC AND PROKARYOTIC CELLS Cells are divided into two categories namely the Prokaryotes and Eukaryotes. These two have varying differences between them. Speaking in simple cell biology words, prokaryotes are primitive, simple organisms that lack membranous cell organelles. The opposite of this are eukaryotes, which are advanced and complex organisms having membrane bound cell organelles. Seemingly simple in structure and markedly different from eukaryote and protist organisms, prokaryotic cells are believed to
