The term GARDEN STARTER can be solved by the four-letter word SEED. A SEED is a small embryonic plant enclosed in a covering called the SEED coat, usually with some stored food. Seeds are the product of the ripened ovule of gymnosperm and angiosperm plants. They are the means by which angiosperms disperse their species and a primary mechanism for the generation of biodiversity. Seeds have been an important development in the reproduction and success of angiosperms, relative to more primitive plants such as mosses, ferns, and liverworts, which do not have seeds and use water-dependent means to propagate themselves.
