Actually they were procaryotic cells. To be more exact, it is a scientific guess.
The first true cells were prokaryotic cells. These were simple life-forms that didn't have a nucleus. The next to evolve were eukaryotic cells which do have a nucleus.
An armadillo is eukaryotic because its cells have nuclei. Prokaryotic cells however do not. Prokaryotes are mainly very simple life forms such as bacteria. Eukaryotes are more advanced life forms such as animals, plants, and in this case an armadillo.
prokaryotic and eukaryotic cells.
There are many forms of parasitic bacteria. The parasitic bacterium that depends on eukaryotic host cells are of the Rickettsia family.
The first true cells were prokaryotic cells. These were the first living organisms and were simple life-forms that didn't have a nucleus.
There are two main forms of locomotion in a eukaryotic cell. They are cilia and flagella. Both can be found on cells.
Butterflies have eukaryotic cells. These kind of cells are found in animals, plants, and fungi. Eukaryotic cells have a membrane-bounded nucleus.
Viruses come in both prokaryotic an eukaryotic forms.
The endoplasmic reticulum (ER) is an eukaryotic organelle that forms an interconnected network of tubules, vesicles, and cisternae within cells.
The definition of eukaryotic is that of any organism having as its fundamental structural unit a cell type that contains specialized organelles in the cytoplasm, characteristics of all life forms except bacteria, blue algae and other primitive organisms.
No, cells in a eukaryotic multicellular organism are specialized for a specific function. Many of these specialized cells come together to form tissues, which forms organs. Each organ is specific to one job needed for life.
A cell with a nucleus and membrane-bound organelles is a eukaryotic cell. Eukaryotic cells are cells make up forms of life like plants, animals, and fungi.
