What is the best evidence that all life evolved from prokaryotic rather than eukaryotic ancestors?
The oldest fossil form of life known is prokaryotic (Archeabacterias)
Which of the three domains has the most ancient fossils?
According to Biologists, the large domain that includes the oldest known fossil cells is called bacteria within the prokaryotic microorganism.
Are fossil sponges one of the oldest known animal fossils?
yes
What kingdoms contain the oldest forms of life on earth?
Domain Bacteria contain the oldest known fossils of cells in bacterial cells.
Which cell organelle is known as cell with in cell?
Mitochondria and plastids (like chloroplasts) are known as cells within a cell because they are believed to have been prokaryotic cells before entering eukaryotic cells.

The oldest fossil form of life known is prokaryotic (Archeabacterias)
How old are the oldest prokaryotic fossils on earth?
The oldest known fossilized prokaryotes were laid down approximately 3.5 billion years ago, only about 1 billion years after the formation of the earth's crust.
Which of the three domains has the most ancient fossils?
According to Biologists, the large domain that includes the oldest known fossil cells is called bacteria within the prokaryotic microorganism.
Does eukaryotic cell have a smaller cell nucleus than an prokaryotic?
Not necessarily, however eukaryotic cells are known in general to be larger and more complicated than prokaryotic cells, so there is a good chance that it will.
When did the first fossils form?
The oldest known fossils are up to 3.5 billion years old.
Is cyanobacteria Eukaryotic or Prokaryotic?
Prokaryote
Are fossil sponges one of the oldest known animal fossils?
yes
What is the differernce between prokaryotic and eukaryotic cells?
The most commonly identified difference is that eukaryotic cells are nucleated, prokaryotic cells are not.Most eukaryotic cells have only one nucleus, but some have more. Some species of a fungus called slime molds are known to have several thousand nuclei in one cell.However the more general difference is that eukaryotic cells contain organelles (e.g. mitochondria, chloroplasts, nucleus, endoplasmic reticulum, Golgi apparatus) and prokaryotic cells don't. These are believed to have originated as symbiotic microorganisms that entered the cells of the ancestors of early eukaryotes and took up permanent residence.

Mitochondria and plastids (like chloroplasts) are known as cells within a cell because they are believed to have been prokaryotic cells before entering eukaryotic cells.
What part of all cells makes energy?
Are we talking about eukaryotic or prokaryotic cells? In prokaryotic cells (bacteria) the cell membrane is the site of the electron transport chain which makes the cells energy currency known as ATP (adenosine-triphosphate) In eukaryotic (plants, animal) cells the major source of energy (ATP) is produced by the mitochondria.
Cell walls are not found on typical cells of?
There are two types of cells that contain a cell wall that is not found in plants. These two are known as prokaryotic and eukaryotic cells.
