    According to the website www.tutorvista.com‚ Prokaryotes differ from eukaryotes in their structure‚ packing‚ density‚ and arrangement of their genes on the chromosome. Differences in cellular structure of prokaryotes and eukaryotes include the presence of mitochondria and chloroplasts‚ the cell wall‚ and the structure of chromosomal DNA. All cells share some common characteristics that make them living things and all organisms are composed of cells which are the basic fundamental unit of life.

    environment. Carries ribosomes that are responsible for the production of proteins (rough). Synthesis lipids from fatty acids and glycerol and transports these to the Golgi body (smooth). Ribosomes – This binds to the rough endoplasmic reticulum and to the mRNA. It also enables translation of mRNA to produce proteins. Golgi apparatus – Receives proteins from the ribosomes via endoplasmic reticulum and chemically modifies them for export (particularly in secreting cells). Produces vesicles to transport
