Belonging to the rose family (Rosaceae), the apple is a unique and widely consumed fruit, but its botanical classification is often misunderstood. The definitive category of fruit is apple is not a simple one, as it belongs to a specific subgroup called pomes.

The average American consumes about 16 pounds of fresh apples annually, yet many are unaware of their botanical classification. Apples, along with pears and quince, belong to a distinct group known as pome fruits, a designation that comes from their unique core structure. This classification is part of the Rosaceae family, or the rose family, which also includes a surprising number of other popular fruits.

Over 7,500 apple cultivars exist, but not one of them is related to the pineapple. This tropical fruit, known for its spiky exterior and sweet interior, is often misunderstood, but is pineapple considered an apple? The definitive answer is no, and the reasons lie deep in their botanical and historical roots.

The cultivated apple, *Malus domestica*, is one of the most widely grown tree fruits in the world. To understand the category of apple, one must explore its botanical classification, which places it firmly within the rose family, Rosaceae, alongside many other familiar fruits.

In a 2022 study, researchers identified 47 chitinase genes in the genome of domesticated apple (Malus domestica), proving that apples have chitinase. These enzymes are vital components of the fruit's pathogenesis-related (PR) protein family, which serves as a frontline defense against threats like fungal pathogens.

With over 7,500 cultivars in existence, the characteristics of an apple can differ wildly depending on the specific variety. From the tart and firm Granny Smith to the sweet and tender Golden Delicious, each apple offers a unique profile of color, texture, and flavor. Understanding these traits can help you choose the perfect apple for eating, cooking, or baking.

Studies show that apple seeds contain a cyanogenic compound called amygdalin, but only in very small, safe concentrations. Contrary to popular myth, the minuscule amount of amygdalin in an apple is not dangerous under normal consumption circumstances.
