what is a molecule
not a single structure but plenty of them; it moves and movements cost lots of energy
caca
seminiferous tubules
antheridium
The structures in the sperm that provide energy are known as mitochondria. They have a main function of producing motility for the human sperm.
seminal vesicles
The tightly coiled structure that produces sperm is called the seminiferous tubules. These tubules are located within the testes, the male reproductive organs.
fructose
The reproductive structure of a gymnosperm is the cone. The cone produces pollen or sperm cells that will later on fertilize a female plants eggs or anthers
the archegonium structure produces haploid egg cells (the female reproductive structure-think "egg" like archEGonium) wheras the antheridium produces haploid sperm cells (the male reproductive structure)
Produces sperm
