核心, 果核
the central part of a fruit that typically contains seeds, like in apples, pears, and pineapples
The core of a fruit is the central, often tough or fibrous, part that contains the seeds or reproductive structures. It is typically surrounded by the flesh or edible portion of the fruit. In some fruits, such as apples and pears, the core contains the seeds housed within a central seed cavity. The core may also include other structures, such as vascular tissues for nutrient transport. While the core is not always consumed, it plays a crucial role in the fruit's development and reproduction, as it houses the seeds necessary for the plant's propagation.
