For the sake of clarity on lichens and mosses ...this is from the Wiki page on Seeds:
A seed is a small embryonic plant enclosed in a covering called the seed coat, usually with somestored food. It is the product of the ripened ovule of gymnosperm and angiosperm plants which occurs after fertilization and some growth within the mother plant. The formation of the seed completes the process of reproduction in seed plants (started with the development of flowers andpollination), with the embryo developed from the zygote and the seed coat from the integuments of the ovule.
Seeds have been an important development in the reproduction and spread of flowering plants, relative to more primitive plants like mosses, ferns and liverworts, which do not have seeds and use other means to propagate themselves. This can be seen by the success of seed plants (both gymnosperms and angiosperms) in dominating biological niches on land, from forests to grasslandsboth in hot and cold climates.
The term seed also has a general meaning that predates the above — anything that can be sown, e.g. "seed" potatoes, "seeds" of corn or sunflower "seeds". In the case of sunflower and corn "seeds", what is sown is the seed enclosed in a shell or husk, whereas the potato is a tuber.
Lost lichens and missing mosses
Urgent action needed after reports declare nearly 50 of Wales' smallest wild plants extinct.
