The term 'Seed Pod' refers to the protective covering of a seed, which can be either a hard or soft shell. An example of a hard seed pod is an ARIL, which is a fleshy, brightly colored covering that encloses the seed of certain plants such as yews and pines. An example of a soft seed pod is a BOLL, which is a dry, leathery, or membranous covering that encloses the seeds of certain plants such as cotton and flax.
