Comparing Eukaryotic and Prokaryotic
Eukaryotic
Larger cells
DNA is linear
Nucleus present-DNA inside
no cell wall in animals
many organelles mitochondria present
large ribosomes
Prokaryotic
Extremely small cells
DNA is circular
Cell wall made of polysaccharide
no mitochondria few organelles
smaller ribosomes
