Where the eggs of gymnosperms and angiosperms are produced. provide the word best described for the definition

Gymnosperms A gymnosperm [Greek for "naked seed"] is a vascular plant that produces seeds that are not protected by fruit but are hidden in a woody cone. They do not have flowers but most retain their leaves year round.  Angiosperms Angiosperms are vascular plants that produce flowers and fruit with one or more seeds. Angiosperms make up two classes: monocot and dicot. Angiosperms make up more than 80% of all plant species, ranging from roses to palm trees.
