List the specific functions of the following:
$(i)$ Rough endoplasmic reticulum
$(ii)$ Golgi apparatus
$(iii)$ Lysosomes
$(iv)$ Mitochondria
$(v)$ Plastids
$(vi)$ Vacuoles

(N/A) $(i)$ Rough endoplasmic reticulum is the site of protein synthesis.
$(ii)$ Golgi apparatus is involved in the storage,modification,and packaging of products in vesicles. It also synthesizes complex sugars from simple sugars and is involved in the formation of lysosomes.
$(iii)$ Lysosomes act as the waste disposal system of the cell by digesting foreign materials and worn-out cell organelles.
$(iv)$ Mitochondria are known as the powerhouses of the cell because they produce energy in the form of $ATP$ through cellular respiration.
$(v)$ Plastids are the sites of photosynthesis in plants and store pigments like chlorophyll.
$(vi)$ Vacuoles provide storage for nutrients and water. In some organisms,they help in the digestion of food and the expulsion of excess water and waste.
