Why does a lemon produce more juice than a orange and tomato?

A lemon typically produces more juice than an orange or tomato due to its higher acidity and water content, which allows for a more abundant liquid extraction. Additionally, the structure of a lemon's cells is more conducive to juicing, as they are filled with juice vesicles that release liquid more easily when squeezed. Oranges and tomatoes, while juicy, have thicker skins and varying pulp structures that can limit juice yield.
