DIFFERENCESCHARACTERISTICS PROKARYOTES EUKARYOTES

SIZE OF CELL Typically 0.2-2.0 m m in diameter

Typically 10-100 m m in diameter

NUCLEUS No nuclear membrane or nucleoli

True nucleus, consisting of nuclear membrane & nucleoli

MEMBRANE-ENCLOSED ORGANELLES

Absent Present

RIBOSOMES Smaller size (70S) Larger size (80S)

DNA lacks histones,Single circular chromosome

Multiple linear chromosomes with histones

CELL DIVISION Binary fission Mitosis

CAPSULE Have capsule Not has capsule

CELL WALLS Cells wall made up of peptidoglycan

Cell walls usually made up of cellulose

Example of organelle

Cellular Organelle Function( s)

1. Nucleus 1.Storage of genetics information2. Synthesis of DNA and RNA

2. Mitochondria 1. Cellular respiration

3. Endoplasmic ReticulumI. Rough ERII. Smooth ER

1. Protein synthesis2. Lipid synthesis

4. Golgi body / apparatus Processing, packaging and distribution of proteins and lipids

5. Ribosomes Protein synthesis

Cellular Organelle Function( s)

6. Lysosome Intracellular digestion

7. Chloroplast Sugar synthesis

8. Cell wall Support and protects cell contents

9. Centriole Formation of basal bodies

10. Vacuole and vesicle Storage of substance

11. Cytoskeleton 1. Provides support to the cell2. Maintains cell shape 3. Aids in cell motility
