PPT-GYMNOSPERMS INTRODUCTION

Gymnosperms Gymno naked sperma seed include simpler and primitive plants They are characterised by the presence of naked ovules borne unprotected on the surface of the megasporophylls.

The Importance of Seeds. Q: What adaptations allow seed plants to reproduce without open water?. A: Adaptations include 1)a reproductive process that takes place in cones or flowers, 2)the transfer of sperm by pollination, and 3)the protection of embryos in seeds.
