Prokaryotes ­ simple cells e.g. bacteria

Eukaryotes ­ cells found in plants and animals that have membranebound organelles

Organelle ­ small cellular structure that has a specific function

Viruses are noncellular/akaryotic and cannot carry out metabolic processes.

Metabolism ­ all the chemical reactions in cells e.g.…
