Practice question

Meaning naked seed reflects condition ovules exposed directly upon sporophyll surfaces or ovuliferous scales without enclosing ovary wall derived from carpel fusion, terminology gymnos Greek naked sperm seed. In conifers ovules sit on adaxial scale surface, ginkgo terminal on stalk, cycads leaf margin ovulate. Integument forms testa not fruit wall, embryo present as zygotic product developing after fertilization, ovules clearly present as precursors before pollination. Lack fruit enclosure distinguishes from angiosperms where carpels fuse into ovary producing true fruit pericarp. Fleshy sarcotesta aril mimicking fruit ecologically not homologous to true pericarp developmentally, so naked designation remains accurate systematics.
