Prokaryotic and Eukaryotic cells
The nucleus is the matter here!
(Pro=No; eu=yes; karyote= nucleus).
# Prokaryotes are bacteria (but not viruses) which do not possess prominent nuclei and most other organelles that are present in the eukaryotic cells, i.e. mitochondria, Golgi, ER etc.
- Chromosomal DNA and the extra-chromosomal circular plasmid DNA are present.
- Plasmidin paracytic prokaryotes contain antibiotic-resistant genes such as ampicillin and tetracyclin
- The cell wall is present and is made up of mucopolysaccharides (peptides+sugars) moiety.
- The cell wall gives protection to the body by inhibiting the action of host body enzyme digestion
- .
- Prokaryotic cell Plasmid DNA
# Eukaryotes possess nuclei and other organelles perfectly in the cell.
- Cell walls in plants are made up of cellulose (a polysaccharide). The cell wall gives physical strength from osmatic and turgor pressure and shape to the plant cell.
- Q: If mitochondria are absent in the bacteria, how do they perform cellular respiration for ATP production?
- Mesosomes formed from the folding of plasma membranes consisting of all the enzymes which can run cellular respiration.
