Prokaryotic cells lack membrane-bound organelles found in eukaryotes. However, prokaryotes must perform many of the same functions as eukaryotes. For THREE of the organelles identified in part (a), explain how prokaryotic cells carry out the associated functions

Nucleus Hereditary information/DNA/chromosomes or RNA synthesis in

cytosol.

Ribosomes Site of protein synthesis.

ER (endoplasmic reticulum) Diffusion of molecules in cytosol.

Rough ER Protein synthesis/transport in cytosol; may be linked to

transcription.

Smooth ER Lipid synthesis or detoxification occurs in cytosol.

Mitochondria Other membranes or cytosolic molecules function in ATP

synthesis.

Chloroplasts Other membranes or cytosolic molecules function in light

absorption/photosynthesis/carbohydrate synthesis.

Plastids Pigments are distributed throughout cytosol or are associated

with membranes.

Vacuole, vesicles Inclusion bodies/granules/large molecules in cytosol.

Cilia or flagella Motility via bacterial flagella
