WebSix facts about prokaryotic cells. Bacteria are an example of prokaryotic cells. Prokaryotic cells do not have a membrane -bound nucleus, their DNA is circular and naked. Prokaryotic cells are very small (an average bacterial cell is around 8 micrometres long). These cells do not have any membrane-bound organelles such as mitochondria. Webeukaryote, any cell or organism that possesses a clearly defined nucleus. The eukaryotic cell has a nuclear membrane that surrounds the nucleus, in which the well-defined chromosomes (bodies containing the hereditary material) are located. prokaryote, also spelled procaryote, any organism that lacks a distinct nucleus …
WebAnabaena: Classification and Characteristics. Anabaena is a genus of nitrogen-fixing cyanobacteria that exist as plankton. The blue-green algae are symbiotic in nature but produce neurotoxins, which are detrimental to plants, wildlife, and even humans. Anabaena are shaped like a string of beads and found mostly in shallow water or in wet soil. WebEukaryotic cells are cells containing membrane-bound organelles and are the basis for both unicellular and multicellular organisms. In contrast, prokaryotic cells do not have any membrane-bound organelles and are always part of unicellular organisms.
