This is an accident of how the first eukaryotic plant cells evolved to be different from other eukaryotic cells billions of years ago. It is what defines eukaryotic plants.
when did the equus frist appear in the fossil record
The first cells on earth were likely prokaryotic. This is because the prokaryotic cells are not complex like eukaryotic cells.
The differnece between this two are as followings- Eukaryotic cells are cells that contain a nucleus. Like you and me. Prokaryotic cells are cells that dont have a nucleus. Like bacteria ( But do contain genetic materials and chromosomes) Hope this helps!

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.

in north America.
Cyanobacteria are the first to appear in the fossil record.
Anatomically modern humans first appear in the fossil record in Africa about 195,000 years ago.
