Accepted Answer

The key difference between spores and seeds is that spores are single-celled reproductive structures while seeds are multicellular embryos. Spores are produced by fungi, algae, and some plants such as ferns, mosses, and liverworts. They are usually smaller than seeds and can travel longer distances through the air, water, and soil. Seeds, on the other hand, are produced by seed plants such as gymnosperms and angiosperms. They contain an embryo, stored nutrients, and a protective coat, and can develop into a new plant when conditions are favorable.
