Scientists are not completely sure, but it is positives that these cells would have to produce their own energy rather than obtaining it by consuming other cells. Also these cells were simple and most likely hollow spherical blogs of plasma membrane with some type of genetic material inside (DNA, RNA, proteins, etc.)

∙ 13y agoLife on the earth has originated from primordial membranes. This is the sequence of events.
- First the hydrocarbon molecules formed and in watery medium became bi-layered membranes.
- A biological big bang occurred which imparted electrical potentials across these membranes. These membrane potentials represent consciousness even now.
- Formation of 'Phantom cells' from membranes which started metabolism inside them. This gave rise to organic molecules.
- Formation of 'True cells' happened gradually. The need to execute repeated tasks resulted in DNA/RNA formation through 'molecular etching'.

What is true about cell specialization?
Is true about cell specialized, the human body contains many different cell types.
Is it true that Animal cells have a cell wall?
That is not true. Plant cells have cell walls. Animal cells have cell membranes, but no cell walls.
