Like humans, cells also need specialised structures to carry out metabolic activities, especially unicellular organisms. So the parts of the cell that help it to carry out the various activities, for example digestion, excretion, respiration and so on are called organelles.
eg: nucleus, endoplasmic reticulum, vacuoles, golgi apparatus or golgi complex
