Final answer:
The correct answer is that a seed provides protection for the plant embryo, nourishes it, and allows plants to disperse their offspring widely.
Step-by-step explanation:
The true statement about reproduction using a seed is that it provides protection for the embryo. Seeds play a crucial role in the reproductive cycle of seed plants, acting as a protective vessel for the developing plant embryo. The seed also supplies nourishment and aids in maintaining dormancy under unfavorable conditions, improving the chances for successful germination and growth when the environment becomes suitable. This adaptation has allowed seed plants to distribute their progeny across both space and time, becoming highly successful in a variety of habitats.
The main purpose of reproduction using a seed is to provide protection for the embryo. Seeds have a tough outer coating that shields the developing embryo from desiccation and other environmental hazards. This protective layer ensures the survival and successful development of the embryo into a new sporophyte.
