Ответы

Ответ:

У папоротников гаметофит представляет собой небольшое, но самостоятельное растение, иногда называемое заростком.

Развивается из оплодотворенной яйцеклетки, или зиготы. На спорофите в специальных органах — спорангиях — в результате мейоза развиваются гаплоидные споры. У цветковых растений, голосеменных и сосудистых споровых (папоротники) спорофит значительно крупнее гаметофита.
