The first eukaryotic cells appear in the fossil record around 2 billion years ago during the Proterozoic eon. The oldest known eukaryotic fossils are single-celled organisms called acritarchs. These early eukaryotes eventually gave rise to more complex multicellular life forms.

Are chloroplasts found in plant cells why?
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 first eukaryotic cell first appear?
Eukaryotic cells are believed to have appeared around 2 billion years ago. This is supported by fossil evidence and molecular data that suggest eukaryotes diverged from prokaryotes around that time.
Were the first cells prokaryotic or eukaryotic?
The first cells were likely prokaryotic, as they are simpler and more primitive compared to eukaryotic cells. Prokaryotic cells lack a nucleus and membrane-bound organelles, while eukaryotic cells have these structures.
When did the Equus first appear in the fossil record?
The Equus genus first appeared in the fossil record around 4 million years ago during the Pliocene epoch.
What are the oldest cells on earth?
The first cells on earth were likely prokaryotic. This is because the prokaryotic cells are not complex like eukaryotic cells.
According to the fossil record when did the first prokaryotic cells appear on your planet?
2.5 billion years ago

Why are the chloroplasts found in plant cells only?
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.

The first forms of life were simple eukaryotic cells?
Actually they were procaryotic cells. To be more exact, it is a scientific guess.
What was the first type of true cells to form on earth was?
Prokaryotic cells were the first type of true cells to form on Earth. These cells lacked a defined nucleus and other membrane-bound organelles, but were able to carry out essential functions of life.
The fossil record suggests that the first animals to evolve lived where?
in north America.
What is the definition of range of a fossil species?
The range of a fossil species refers to the span of time during which the species existed on Earth. It is determined by the oldest and youngest known occurrences of that species in the fossil record. The range provides information about the species' period of existence and can be used to study evolution and environmental changes over time.
When did eukaryotic cells first appear?
2.1 billion years ago
