Chloroplasts likely first entered a host cell as food before establishing a successful merger with the cell so they were not digested.Ages ago, as land plants were evolving, they ran into a few impediments. Soil can sometimes prove a nutrient-poor and inhospitable environment. In order to grow and thrive, plants need nitrogen to make proteins, but they lack the chemistry set to convert free nitrogen in the air into a form their cells can use. l, e, d, l, i. To overcome these obstacles, early plants struck deals with co-evolving bacteria and fungi. Bacteria will take steps to insure their survival. This can take the form of creating resting structures that allow the microbe to sleep during bad times. During abundant times, many microbes will store excess carbon, nitrogen, sulfur or phosphorous in inclusions in the cell. Not only is structure important to understand functional relationships, it's also fascinating to observe what these little architects come up with.

Each new discovery relied on previous ones and in turn spawned further inquiry. A web of interdependent concepts evolved over time through the work of scientists in many related disciplines and nations. Often the research of one individual impacted the efforts of another studying a completely different problem. Keep this in mind as you look at this history. Major advances in bacteriology over the last century resulted in the development of many effective vaccines (e.g., pneumococcal polysaccharide vaccine, diphtheria toxoid, and tetanus toxoid) as well as of other vaccines (e.g., cholera, typhoid, and plague vaccines) that are less effective or have side effects. Another major advance was the discovery of antibiotics. These antimicrobial substances have not eradicated bacterial diseases, but they are powerful therapeutic tools.
