Gram positive bacteria and cyanobacteria have no nuclei; also, they predate eukaryotes.
cyanobacteria
Cyanobacteria is the phylum of bacteria. Often called blue-green algae, it belongs to the bacteria domain and the eubacteria kingdom.
Yes, cyanobacteria are classified as gram negative bacteria.
Eubacteria is a kingdom of prokaryotic organisms that includes various types of bacteria, while cyanobacteria are a specific group of photosynthetic bacteria within the kingdom Eubacteria. Cyanobacteria are known for their ability to carry out oxygenic photosynthesis and produce oxygen as a byproduct. They are often referred to as blue-green algae due to their color and aquatic habitat.
Cyanobacteria are a type of bacteria capable of photosynthesis, often referred to as blue-green algae, while eubacteria is a larger category that includes various types of bacteria other than cyanobacteria. Cyanobacteria have specialized chlorophyll pigments that allow them to perform photosynthesis, while eubacteria cover a wide range of bacterial species with diverse characteristics and functions.
eubacteria, cyanobacteria, and I can' t find the other one, ARCHAEBACTERIA
Cyanobacteria is not a major branch of domain Bacteria. Eubacteria, on the other hand, is a major branch and includes many different types of bacteria. Cyanobacteria is a specific group of photosynthetic bacteria within the domain Bacteria.
Cyanobacteria are now classified as part of the domain Bacteria. They are prokaryotic organisms that are capable of performing photosynthesis like plants and algae.
Archaebacteria and eubacteria.
Eubacteria and Archaeabacteria.
Eubacteria and Archaebacteria
I'm sorry for the answer you were previously given on this question. The answer is eubacteria.
