L3: EUKARYOTES VS. PROKARYOTES
==Characteristics of Prokaryotic Cells==
- Bacterial cell wall – Peptidoglycan
- Has a long single strand of DNA plus
- Asexual reproduction by fission, Sexual production unknown.
- Kingdom Monera (bacteria and cyanobacteria)
==Characteristics of Eukaryotic Cells==
- More complex
- Either unicellular or multicellular
- Plant cell wall-cellulose Fungi – chitin
- 80’s ribosomes
- Asexual reproduction by mitosis and Sexual reproduction by fusion of gametes
- Kingdom of Animalia, Kingdom of Plantae, and Kingdom of Fungi
The distinction between prokaryotes and eukaryotes is considered to be the most important distinction among groups of organisms. ==Eukaryotic== cells contain membrane-bound organelles, such as the nucleus, while prokaryotic cells do not. Differences in the cellular structure of prokaryotes and eukaryotes include the presence of mitochondria and chloroplasts, the cell wall, and the structure of chromosomal DNA.
==Prokaryotes== were the only form of life on Earth for millions of years until more complicated eukaryotic cells came into being through the process of evolution.
