Vocabulary : Spermatogenesis to Spermatophyte

Spermatogenesis : The development of the spermatozoids.
Spermatogenetic : Relating to, or connected with, spermatogenesis; as, spermatogenetic function.
Spermatogenous : Sperm-producing.
Spermatogonium : A primitive seminal cell, occuring in masses in the seminal tubules. It divides into a mass (spermosphere) of small cells (spermoblast), which in turn give rise to spermatozoids.
Spermatoid : Spermlike; resembling sperm, or semen.

Spermatoon : A spermoblast.
Spermatophore : Same as Spermospore. ;; A capsule or pocket inclosing a number of spermatozoa. They are present in many annelids, brachiopods, mollusks, and crustaceans. In cephalopods the structure of the capsule is very complex.
Spermatophorous : Producing seed, or sperm; seminiferous; as, the so-called spermatophorous cells.
Spermatophyta : A phylum embracing the highest plants, or those that produce seeds; the seed plants, or flowering plants. They form the most numerous group, including over 120,000 species. In general, the group is characterized by the marked development of the sporophyte, with great differentiation of its parts (root, stem, leaves, flowers, etc.); by the extreme reduction of the gametophyte; and by the development of seeds. All the Spermatophyta are heterosporous; fertilization of the egg cell is either through a pollen tube emitted by the microspore or (in a few gymnosperms) by spermatozoids.
Spermatophyte : Any plant of the phylum Spermatophyta.
