Final answer:
Eubacteria have prokaryotic cells, which lack a membrane-bound nucleus and other membrane-bound organelles. Eukaryotic cells, in contrast, have a membrane-bound nucleus and other membrane-bound organelles.
Step-by-step explanation:
Cells are classified into two broad categories: prokaryotic and eukaryotic. Eubacteria, also known as bacteria, have prokaryotic cells. Prokaryotic cells lack a membrane-bound nucleus and other membrane-bound organelles. They have a simple structure and are usually smaller than eukaryotic cells.
Eukaryotic cells, on the other hand, have a membrane-bound nucleus and other membrane-bound organelles. They are more complex in structure and larger in size compared to prokaryotic cells. Animal cells, plant cells, fungal cells, and protist cells are all examples of eukaryotic cells.
Eubacteria, which belong to one of the three domains of life, consist of prokaryotic cells. Cells are broadly classified as either prokaryotic or eukaryotic. The defining feature of prokaryotic cells, such as those of eubacteria, is that they do not have a nucleus. Instead, their genetic material, DNA, is typically organized into a single circular chromosome that floats freely within the cell. Prokaryotic cells also lack other membrane-bound organelles found in eukaryotic cells. They are often single-celled and are considered more ancient and simpler in structure when compared to eukaryotic cells, which have a nucleus and membrane-bound organelles. Prokaryotic organisms, including eubacteria, play critical roles in environments and as part of the human microbiota.
