Quizplus · Accepted Answer

The mature seed consists of the seed coat, which protects the contents of the seed, the nutritive tissue, which provides energy and nutrients for the developing embryo, and most importantly, the embryo itself. The embryo is the tiny, developing plant that will eventually grow into a mature plant. Pollen grains are not part of the mature seed, as they are involved in pollination and fertilization. Fruits are structures that develop from the ovary of a flower after fertilization and are not always present in mature seeds. The integument is a layer of protective tissue that surrounds the ovule, which will eventually develop into the seed coat, and is not part of the mature seed itself.
