Symbiotic Relationship fix nitrogen many pathogenic aid in human digestion aid in digestion many pathogenic (malaria, African sleeping sickness, amoebic dysentery) cellulose digestion many pathogenic (athlete’s foot, yeast infection, ringworm) lichen epiphyte mycorrhizae mistletoe parasitic worms, barnacles, clownfish
Ecological Importance fix nitrogen decomposers decomposers algae major aquatic oxygen & food producers algal bloom decomposers major oxygen & food source (photosynthesis - trophic level 1) human impact on environment
Examples Escherichia coli
Streptococcus methanobacteria algae, diatoms, amoebas, lichen, yeast, mushrooms trees flowers grass sponges

mammals

The six kingdoms are grouped according to five major categories in addition to other major characteristics. The categories are:

I. CELL TYPE: (kind of cell) all cells are made of the same organic material) A. PROKARYOTIC: no organized nucleus, no internal membranes, peptidoglycan cell wall, have ribosomes (small), bacteria and blue-green algae B. EUKARYOTIC: organized nucleus, internal membranes, nonpeptidoglycan cell wall

II. CELLULAR ORGANIZATION: A. NUMBER OF CELLS 1. UNICELLULAR: (single-celled) all life functions, solitary or colonial (chains or clumps) 2. MULTICELLULAR: (many-celled) a. hyphae body form b. tissue differentiation (limited to advanced organisms) B. LEVELS OF ORGANIZATION (Tissue Differentiation) 1. cells, 2. tissues, 3. organs, 4. organ

Dougherty 3/15/2012 Biology Half Sheet 1. Humans are classified like any other organism by their kingdom, phylum, class, order, family, genus, and species. Humans are in the kingdom Animalia. This is because we are heterotrophs and are multicellular. Humans are in the phylum Chordata. This is because we have a backbone. We belong in the class Mammalia because we give milk, have hair all over, and we give birth to offspring. We are in the order Primates because we have and opposable thumb.…

R selection Use a batch culture also known as a serial culture (the liquid culture in the test tubes). Use this because they have an abundant amount of nutrients, just make sure that you transfer the culture to a new fresh tube everyday so the bacteria will continue in the exponential phase of growth, therefore always being selected to grow as fast as possible. (you could also use a chemostat which is a continuous culture system) K selection K selection you could use continuous culture device…
