Spores vs. Seeds — What's the Difference?
Edited by Tayyaba Rehman — By Fiza Rafique — Published on December 3, 2023
Spores are microscopic reproductive units of fungi, algae, and some plants, while seeds are the mature fertilized ovule of flowering plants containing an embryo.

Key Differences
Spores are tiny, typically single-celled reproductive units produced by certain bacteria, fungi, algae, and non-flowering plants. They are formed without fertilization and can develop into new organisms without fusion with another reproductive cell. Seeds, on the other hand, are developed from the fertilized ovules of flowering plants and contain a plant embryo, nutrients, and a protective outer covering.
Spores are known for their resilience and ability to survive in extreme conditions, including drought or intense heat. This durability allows them to remain dormant for extended periods until they find a conducive environment to germinate and grow. Seeds, while also capable of dormancy, generally rely on a coat and stored food to support the young plant's growth until it can produce its own food through photosynthesis.
When discussing dispersal, spores are often lightweight and can easily spread through air, water, or other organisms. Some spores are equipped with unique structures to facilitate their dispersal, ensuring the continuation of their species. Seeds utilize various dispersal mechanisms, including wind, animals, water, or even explosive mechanisms, ensuring they land in a location suitable for germination.
Regarding origin, spores can be produced by an array of organisms across different kingdoms of life. For instance, ferns, which are plants, produce spores, as do fungi and certain bacteria. Seeds are exclusively the domain of the plant kingdom, more specifically, the angiosperms or flowering plants.
It's essential to recognize that both spores and seeds play crucial roles in the continuation of their respective species. While they serve a similar overarching purpose of reproduction, their structures, origins, and mechanisms of action showcase nature's diverse strategies for life propagation.
