Document Summary

Describe the difference between a basic and applied biological science. Basic biological science is the foundation for understanding many processes of physiology, ecology, and genetics which applied biological science helps us to solve many problems relating to health, agriculture, and industry. Phylogenic trees show the evolutionary relationships between cells. All cells carry out or have the potential to carry out _metabolism/life processes_. Know the seven scientists from lecture #1 and their contributions to the study of microbiology: robert hooke. Coin the term cells on viewing cork: antoni von leeuwenhoek. First to describe bacterial cells wee animalcules : ferdinand cohn. Defined bacterial as chlorophyll-less cells of characteristic shape that multiply by cross division and live as single cells, filamentous cell chains, or cell aggregates. First to describe the life cycle of endospore forming bacteria established a scientific journal of bacteriology. Developed initial classification scheme for bacteria: martinus beijerinck.
