Sporoderm: The sporoderm refers to the outer layer or covering of a spore.The sporoderm protects the genetic material (pollen grain or spores) and helps in its dispersal.

Spermoderm: The spermoderm, also known as the seed coat, is the protective covering of a seed. It is formed from the integuments of the ovule after fertilization. The spermoderm consists of one or more layers and helps in protecting the embryo and the endosperm inside the seed. It also aids in seed dormancy and germination.

In summary, the sporoderm refers to the outer layer of a spore, while the spermoderm represents the protective covering of a seed.

Hence, the correct answer is option 3.
