How have eukaryotic cells evolved?
Unicellular organisms may have developed from procaryotes to increase metabolic efficiency.
- Unicellular organisms have developed from prokaryotes to increase metabolic efficiency.
- Eukaryotic cells are more specialised cells within the Protista kingdom. They can be both unicellular and multicellular organisms. They have membrane bound organelles (chloroplast and mitochondria), and a nucleus, which contains long strands of DNA structured in chromosomes.
- Some of the simple prokaryotic cells may have engulfed other cells which became internal structures or organelles and evolved into first eukaryotic cells.
- The theory has been popularised by L. Margulis. It is now supported by detailed experimental testing.
