The statement is pointing out the continual nature of the alternation of generations life cycle. The acorn is a fruit, a dry one which contains a seed, product of an ovule, made by a female gametophyte and pollinated by pollen from a male gametophyte. These gametophytes are dependent on an oak tree, a sporophyte. The acorn makes the oak tree, which repeats these steps to produce more acorns.
