Main difference between Prokaryotes and Eukaryotes
Prokaryotes:
- Prokaryotes includes bacteria, blue-green algae, mycoplasmas and PPLO.
- They are smaller and multiply more rapidly.
- They vary greatly in shape and size.
- All prokaryotes have a cell wall and cell membrane.
- No well defined nucleus.
- Matrix is filled with cytoplasm.
- In addition to genomic DNA, it has smaller DNA's called Plasmids which is resistant to antibiotics.
- No organelles are present except ribosomes.
- It has unique Inclusions. Inclusions is the reserve material stored in the cytoplasm.
- Differentiated form of cell membranes called mesosomes is the characteristic of prokaryotes.
Eukaryotes:
- Eukaryotes includes protists, plants, animals and fungi.
- Compare to prokaryotes, they multiply slowly.
- The cells are not identical.
- All eukaryotes do not have cell walls.
- Well defined nucleus with a nuclear envelope.
- Cytoplasm have many compartments due to presence of cell organelles.
- Genetic material is organised into chromosome.
- Many membrane bound cell organelles are present such as Endoplasmic reticulum, Golgi bodies, Golgi apparatus, Lysosomes, Vacoules, Mitochondria, Plastids, Ribosomes.
- It have complex locomotary and cytoskeletal structures like cilia,flagella.
- Ribosomes are present in both the cells i.e. in prokaryotes and eukaryotes.
