Bacteria are single celled microbes. The cell structure is simpler than that of other organisms as there is no nucleus or membrane bound organelles. Instead their control centre containing the genetic information is contained in a single loop of DNA. Some bacteria have an extra circle of genetic material called a plasmid. The plasmid often contains genes that give the bacterium some advantage over other bacteria. For example it may contain a gene that makes the bacterium resistant to a certain antibiotic.
Bacteria are classified into 5 groups according to their basic shapes: spherical (cocci), rod (bacilli), spiral (spirilla), comma (vibrios) or corkscrew (spirochaetes). They can exist as single cells, in pairs, chains or clusters.
The creosote bush has two significant adaptations that allow it to survive for prolonged periods without water. The first adaptation is its small, waxy leaves which minimize the amount of water that evaporates from them. The second adaptation is its wide, shallow network of roots that captures as much water as possible when it becomes available. Hope this help you.
