1. 1. Microscope Development A. Definition B. History of Cell Biology INTRODUCTION I. Cell Cell Biology

a. Zacharias Janssen, 1595 first light microscope c. Robert Hooke, 1665 coined Cellulae d. Anton VanLeeuwenhoek, 1672 Homunculus andAnimalcules b. Galileo, 1609 focusing device

e. Charles Spencer, 1850s first compound scope f. Max Knot & Ernst Ruska, 1933 first electron microscope

2. 2. Basics of Cell Theory

a. Robert Dutrochet, 1824 plants made of cells c. Theodor Schwann & Matthias Schleiden, 1839 Cell Theory i. The cell is the basic unit in living organisms. b. Robert Brown, 1824 Brownian motion & the nucleus ii. The cell is the building block of organisms.

e. Rudolph Virchow, 1859 Spontaneous Generation d. J. Purkinji, 1840s coined the term protoplasm iii. Cells arise from preexisting cells.

3. 3. Cellular Control

a. Karl VanNageli, 1846 plant cells derived from direct division of maternal cells d. Frank Meischer, 1871 proposed nuclein material of nucleic acids b. E. Strausburger & Walter Fleming, 1840s directions for growth and division of cells contained in the nucleus c. Gregor Mendel, 1860s proposed a hereditary molecule was responsible for expression of traits in an organism

d. Robert Altmann, 1889 purified nucleic acids into purine and pyrimidine bases DNA in all cells, while RNA variable e. James Watson & Francis Crick, 1953 summarized research and built model of DNA

2. Strategies

1. Lytic = inject, insert, take over, direct, and destroy Figure 18.6

2. Lysogenic = same except hide for a time then lytic Figure 18.7
