Here's some vocabulary words that you will need to know when learning about RHIZOBIA! (Katie)

 

- Nitrogen = it is a gas, that makes up 78% of the atmosphere, it also is found in all living tissues.

- Fix = to secure something (in this sense nitrogen) onto something else (in this sense a root).

- Proteobacteria = a major group of bacteria, including bacteria in charge of fixing nitrogen in plants.

-  Microbe = A very tiny form of life -- microbes include bacteria, fungi, and protozoan parasites.

- Legumes = A pod, such as that of a pea or bean, that splits into two valves with the seeds attached to one edge of the valves.

- Nodule =a special structure of roots of certain plants which contain the symbiotic, nitrogen fixing bacteria Rhizobium.

- Nutrients = the necessary components of food that microbes and all life require to exist and grow. Essential elemental nutrients include such basic molecules as nitrogen, carbon, oxygen, hydrogen, phosphorus, potassium and trace minerals.

- Proteins = an important molecule that is found in all life. Proteins are polymers, that is, long strings of individual amino acids.

- Symbiosis =  an ecological relationship between two or more different species living together in direct contact. There are several types of symbiotic relationships, including parasitism, in which one organism hurts the other; commensalism, in which one organism benefits without hurting the other; and mutualism, in which both partners gain from the association. In microbial ecology when the term symbiosis is used, unless stated otherwise, it refers to mutually beneficial relationships.
