Q:

What are the advantages of seeds over spores?

A:

Quick Answer

Seeds, when compared to spores, have distinct advantages due to their hard outer shells and internal structures called endosperms, which provide essential nutrients for enclosed seedlings. Seeds are found only in flowering plants and gymnosperms. They contain embryos deep within their centers, which are surrounded by a sack of nutrients and minerals enclosed by a tough protective outer shell that protects the growing seed from predation and life-threatening exposure to the elements.

Full Answer

The hard outer shells of seeds are perhaps their most valuable assets. Seed coats help protect the growing seedlings from damage caused by farm equipment and machinery, desiccation and predation by bugs, insects and birds. The shells also protect against potentially harmful conditions such as wind, heavy rain, frost and extreme heat. These hard outer shells are also quite helpful in protecting species located in fire-prone areas: unlike spores, which wilt and die in high temperatures, seeds protect their inner embryos from destruction during fires, enabling them to safely remain dormant and continue growing. The endosperms in seeds are also important contributors to the growth and success of the enclosed embryo. Endosperms, much like human wombs, supply seedlings with the nutrients and minerals they need to fully grow and develop.

  • Q:

    Why do seeds need to be dispersed in new places?

    A:

    Seeds need to be dispersed away from the parent plant to ensure the survival of the seedlings and the species as a whole. If seeds remain close to the parent plant, the seedling will have to compete with the parent for access to sunlight, nutrients and water.

    How does pollination occur?

    A:

    Pollination may occur as cross-pollination between plants, or when bees, insects and birds transport and replant pollinated seeds and spores. Pollination takes place naturally in several ways, without human intervention. Some plants have the ability to repopulate among each other via the technique of cross-pollination, although most organisms rely on wind currents or pollinators, such as bees, birds and other insects to complete the process.

    How do ferns reproduce?

    A:

    Ferns reproduce through their spores, which are produced in very small spots called sori. Each sorus consists of numerous tiny, spherical granules that contain sporangia. Once the sporangia mature, they burst and release spores into the wind, and this is how new ferns emerge.
