We can compare prokaryotic cells and eukaryotic cells in following points:
• The prokaryotic cells are simple and primitive type of cells whereas •Eukaryotic cells are complex and advanced cells.
•The DNA is small and circular in prokaryotic cells whereas the DNA is large and linear in eukaryotic cells.
•In prokaryotic cells 70s type of ribosome is found in cytoplasm but in Eukaryotic cells both 70s (inside cell organelles) and 80s (in cytoplasm) are found.
• In prokaryotic cells cellular respiration takes place through cell membrane but in eukaryotic cells cellular respiration takes place through mitochondria.
Hope it helps!
