Patterns of Bacterial Growth

Introduction

For the purposes of identifying patterns of growth, bacteria colonies can be through of as multicellular organisms. (info about communication)

Patterns of growth are a result of bacteria adapting their behavior to suit their environment.

Select a topic that includes microbes (bacteria, protist, fungi, or algae). Any kind of topic is possible, because all living organisms and ecosystems include microbes. For example, Google "kangaroo bacteria".

Compose a title for your page. Type your exact title in the Search window, then press Go. The MicrobeWiki will invite you to create a new page with this title.

Open the class template page in "edit." Copy ALL the editable text. Then go to YOUR OWN page; edit tab. PASTE into your own page, and edit.

what is it?

identifying characteristics: A bump or branch that sticks out will not be rounded or smoothed over by new growth, but emphasized. It's more likely to catch a wandering particle because it has three facets available for growth, compared to a particle in a line, which only has one facet.

Agar Density

Include some current research, with at least one image.

Nutrient Density

Include some current research, with a second image.

Conclusion

Overall text length should be at least 1,000 words (before counting references), with at least 2 images. Include at least 5 references under Reference section.
