microscopes; Mathias Schlieden- German botanist- all plants made up of living cells; Theodor Schwann- zoologist, all animals made up of cells; Rudolph Virchow- all cells come from preexisting cells. 3. According the Virchow, all cells are formed from other cells. 4. Three advantages of using light microscopes are they are simple and easy to use, inexpensive, and magnifies up to 2000 times. 5. The advantages of using electron microscopes are its expansive, it has 3D surface features, magnifies up to 100,000 times. 6. An organelle is one of several formed bodies with a specialized function, suspended in the cytoplasm and found in eukaryotic cells. 7. g 8. g 9. In order to maintain efficiency in providing the parts of the cell to obtain the needed nutrients, the cell size must consists of a surface area greater than the volume of the cell. This allows for specializations, and for larger organisms. 10. Unicellular organisms carry out the functions of life. 11. d 12. Tissue is an integrated group of cells with a common structure and function. Organs are a specialized center of body function composed of several different types of tissues. Organ systems are the functions of all the organs working together in a particular system, i.e. digestive system. 13. Drawn on separate sheet. 14. Cell wall- provides structure for the plant cell and protects cell from mechanical damage. Plasma Membrane-at the boundary of each cell, functions as a a selective barrier that allows u sufficient passage of oxygen, nutrients, and wastes to served the entire volume of the cell.
