In botany, what is a common example of a seed?

In botany, a seed is typically defined as an embryonic plant enclosed in a protective outer covering, often along with some stored food. The mango pit exemplifies a seed because it contains the embryo of the future mango plant. The hard outer layer of the pit helps protect the embryo until conditions are favorable for germination.

While acorns, pea pods, and kernels are also related to seeds, they are categorized differently; for instance, acorns are the seeds of oak trees, while a pea pod contains multiple seeds, and a kernel (like on a corn cob) refers to the seed of a cereal plant. The mango pit stands out as a clear and recognizable example of a single seed containing the necessary components for the development of a new plant.
