The coconut can refer to the whole coconut palm, the seed, or the fruit. Coconuts are known for their versatility of uses, ranging from food to cosmetics. The inner flesh of the mature seed forms a regular part of the diets of many people in the tropics and subtropics. Coconuts are distinct from other fruits because their endosperm contains a large quantity of clear liquid, called "coconut milk" and when immature, may be harvested for their potable "coconut water", also called "coconut juice". Tamilnadu pollachi coconut is a thick lentil weighing 500 to 600 grams.
