It was single celled, and probably something similar to an algae. Algae are eukaryotes. Cyanobacteria (blue green "algae") are actually prokaryotes. Eukaryotes have been around some 1.5 to 2 billion years.
Scientists infer this by studying the evolution of life on Earth. The first living organisms likely evolved in an anaerobic (oxygen-free) environment, as oxygen levels were not initially present in significant amounts on Earth. These organisms would have been adapted to survive in environments without oxygen, and the need for oxygen likely evolved later as more complex organisms developed.
Scientists examine the creatures cell structure to see if it is prokaryotic or eukaryotic. Prokaryotic organisms are usually simple organisms and eukaryotic ones are complex. For example, humans are eukaryotic. Bacteria is prokaryotic.
both animal and plant cells have a nucleusboth animal and plant cells have a nucleusAnswer (improved)A nucleus can be found in eukaryotic cells. Prokaryotic cells lack nuclei. bacteria
Yes, eukaryotic cells have structures like flagella or cilia that help them move. They can also undergo processes like amoeboid movement to change shape and move. Organisms made up of eukaryotic cells, like animals and fungi, are also capable of mobility.
Oxygen first entered Earth's atmosphere through the process of photosynthesis by early cyanobacteria and other photosynthetic organisms. These organisms produced oxygen as a byproduct of their metabolic processes, gradually increasing the amount of oxygen in the atmosphere over millions of years.
The first eukaryotic organisms on earth were likely single-celled organisms such as protists, which are a diverse group of organisms that have a nucleus and other membrane-bound organelles. These organisms are thought to have evolved around 1.6-2.1 billion years ago.
Prokaryote
Multicellular organisms are eukaryotic.
Animals are not prokaryotes.They are eukaryotic organisms.
Eukaryotic cells have a nucleus and other membranebound organells, while prokaryotic cells don't
No most unicelluar organisms are not eukaryotic alot of them are prokaryotic
The primary characteristic used for the first division of organisms is whether they are prokaryotic or eukaryotic. Prokaryotic organisms lack a true nucleus and membrane-bound organelles, whereas eukaryotic organisms have a distinct nucleus and membrane-bound organelles within their cells.
The first organisms are believed to have been simple archaebacterias. It is believed that, due to it's ability to live in harsh conditions and the design that is much simpler than that of a eukaryotic cell, they were the first to inhabit the Earth.
