Bacteria have 70s ribosomes.Eukariyotes have 80s ribosomes
Actually a ribosome is a small organelle that is found in both eukaryotic and prokaryotic cells. However, the ribosome in a prokaryotic cell differs in shape compared to the ribosome in a eukaryotic cell.
A free ribosome is a ribosome that is not attached to the rough endoplasmic reticulum and is thus suspended in the cytoplasm.
Ribosome assembly begins in the nucleolus of a cell.
Ribosomes are not membrane bound, they are free cytoplasmic organelles responsible for the translation of cytoplasmic mRNA's. When a ribosome begins to synthesize proteins that are needed in some organelles, the ribosome making this protein can become "membrane-bound". In eukaryotic cells this happens in a region of the endoplasmic reticulum (ER) called the "rough ER". The newly produced polypeptide chains are inserted directly into the ER by the ribosome and are then transported to their destinations. Ribosome in eukaryotes are called 80S ribosomes and consist of a small 40S subunit and a larger 60S subunit. Prokaryotes have 70S ribosomes consisting of a 30S and 50S subunits. Hope this helps.
The site of ribosome synthesis is in the nucleolus of eukaryotic cells. The nucleolus is a specialized region within the cell nucleus where ribosomal RNA (rRNA) is transcribed and ribosomal subunits are assembled before being exported to the cytoplasm for final maturation.
Prokaryotic and eukaryotic
in prokaryotic cell ribosome is partly synthesised from nucleoid and partly from pre-exsisting ribosomes. in eukaryotic cell ribosomes are partly synthesised from nucleorar organiser region and partly from pre-exsisting ribosomes.

ribosome
most of the antibiotics kill or inactivate bacteria by inhibitting the protein synthesis... protein synthesis consists of 'transcription' and 'translation'.. the translation process requiers mRNA and ribosomes.Human(eukaryotic) ribosome is different from bacterial(prokaryotic) ribosome... Antibiotics inhibit the protein synthesis by altering the ribosomal constitution.Since human ribosomes are different from bacterial ribosome,the substances which are harmful to bacterial ribosome doesn't harm human ribosomes.. Thus human cells are immune to antibiotics..
Eukaryotic
The ribosomes produce proteins.
prokaryotic and eukaryotic cells.
The antibiotic binds to the ribosome of the prokaryotic cell, so it inhibits the proteins translation, hence the cell dies. You have to consider that prokariotic ribosome it´s different to eukaryotic ribosome, so this antibiotic doesn´t affect our cells, only the target bacteria

ribosome
No. A ribosome is a complex of protein and RNA molecules found inside both prokaryotic and eukaryotic cells. Its function is to translate messenger RNA into protein.
