The tree's ellipsoidal yellow fruit is used for culinary and non-culinary purposes throughout the world, primarily for its juice, though the pulp and rind (zest) are also used in cooking and baking. The juice of the lemon is about 5% to 6% citric acid, which gives lemons a sour taste. Fun Fact: Know how they say to roll a lemon on a counter top to break the cells inside that hold the liquid in order to get more juice out of juicing them? Well, you can microwave them for 20 seconds as well, just to get every bit possible! You should be able to get 2-3 tablespoons of juice per lemon.

The fruit is yellow-orange skinned and generally, an oblate spheroid in shape; it ranges in diameter from 10–15 cm (3.9–5.9 in). The flesh is segmented and acidic, varying in color depending on the cultivars, which include white, pink, and red pulps of varying sweetness (generally, the redder varieties are the sweetest). Fun Fact: It is named grapefruit due to the way it grows – in bunches like grapes. They have fleshy interiors that are often found in pink, red or white color.
