NettetThe eggs of amniotes also contain four additional extra-embryonic tissues: the chorion, amnion , allantois, and yolk sac, shown below. Extra-embryonic membranes are membranes present in amniotic eggs that are derived from the embryo, but are not actually part of the body of the developing embryo (thus “extra”-embryonic). Zoologists characterize amniotes in part by embryonic development that includes the formation of several extensive membranes, the amnion, chorion, and allantois. Amniotes develop directly into a (typically) terrestrial form with limbs and a thick stratified epithelium (rather than first entering a feeding larval tadpole stage followed by metamorphosis, as amphibians do). In amniotes, the transition fro… canon lide 220 software windows 11
