Mitochondria and chloroplasts have their own DNA
Mitochondria and chloroplasts have their own DNA.
The presence of cellular structures in eukaryotic cells are similar to prokaryotes. Mitochondria and chloroplasts are thought to have once been prokaryotic cells that were incorporated into larger prokaryotic cells. There are a number of biochemical similarities between the eukaryotic organelles and prokaryotic cells. Eukaryotic organelles are still the same size as the prokaryotic cells from which they are believed to have been derived.
Multicellular organisms
Although there is no fossil evidence for the evolution of eukaryotes from prokaryotes, scientists have inferred this through studying modern organisms. Scientists believe that eukaryotes evolved from prokaryotes because both have RNA and DNA as genetic material, contain ribosomes, and also utilize the identical 20 amino acids.
They are eukaryotes, multicellular, have nuclei, and have cell walls.
Prokaryotes are a lot simpler than eukaryotes so it can be assumed that prokaryotes evolved before eukaryotes.
Scientists thing protists evolved from archaea, which are simply single celled organisms.
Mitochondria and chloroplasts have their own DNA.
Unicellular organisms evolved first; and from them evolved the multicellular organisms. But that leads onto another question as to why multicellular organisms evolved.
Prokaryotes are much simpler organisms than eukaryotes. It is thought that eukaryotes evolved from prokaryotes. In both cases the evolution process was lengthy and similar to the evolution of other organisms.
(; No, there's some things that are unicells. Humans, and larger types of organisms are multicellular. Small organisms are unicells because their body ain't large enough and they don't need alot of cells like us. ;)
unicellular organisms are made up of only one cell whereas multicellular organisma are made up of many cells working in coordination. unicellular organisma are not evolved and thus are prokaryotes whereas mukticellular organisms have eukaryotic cells.

Probably a form of bacteria. They evolved into multicellular organisms. Some evolved into plants because they could do photosynthesis
Animals in the kingdom Animalia evolved from simple multicellular organisms around 600 million years ago. Their evolutionary path can be traced back to a common ancestor shared with other multicellular organisms like sponges and jellyfish.
The first forms of life were single-celled amoeba - these rapidly evolved into many multicellular organisms eventually giving rise to the human race.
They are eukaryotes, multicellular, have nuclei, and have cell walls.
