Juicy, acidic, but still flavourful, lemon is one of the most widely used citrus fruits worldwide. The fruit is a modified berry with tough, leathery rind. Lemon’s peel contains many volatile oil glands in pits. Interior flesh is composed of segments, called carpels, made up of numerous juice-filled vesicles that are specialized hair cells. Mature lemons turn yellow from green. Lemons are acidic because of citric acid which aids in smooth digestion, and helps dissolve kidney stones.
