role of cyanobacteria

[=)]

What is the role of cyanobacteria in the development of photosynthesis?

thanks

Please explain what it is that you want to know...Cyanobacteria is very important, as it produces a great deal of the oxygen we breathe. Plants are also thought to have had a common ancestor with cyanobacteria (That's biospeak for "have evolved from," a saying not really correct, and any biologist will refute the phrase "having evolved from" ).

Photosynthesis did not depend on any one species to form. It happened so on a molecular level within any photosynthetic organism.

This type of bacteria makes up most of the energy in the world.

It is found in most seaweeds and ocean bacterias. They produce over 50 percent of the earths photo enegery so they are extremely important

Your estimate might be a little conservative =D Cyanobacteria is usually grouped with phytoplankton, and the entire group is responsible for up to 70% of the world's oxygen's release from Carbon Dioxide.

Well, cyanobacteria evolved from eukaryotic chlorolasts, which in turn are found in plants today. And since they produce oxygen as a by-product of photosynthesis, their important role in photosynthesis over millions of years is to basically change our atmosphere from being CO2-rich to O2-rich. Essentially, their ultimate function in the process made what we are today.

Isn't that just a summary of what was said already? =D

i got this big test to take an i need som help.
i need to padd it so i can pass this class.

1.what are the characteristices of prokayotes?
2. what does the process of cellular respiration do?
3.what is the major atmospheric byproduct of photosynthesis?

Must be a bummer for ya...

It is not found in seaweed. Rather it is believed that through endosymbiosis between Cyano and other singled celled organisms that seaweed formed. The only relationship is DNA.
