BEHOLD: Sword ferns! Point leaves mean a feisty fern!

Behold, one of the first terrestrial plants to possess a working vascular system! Finally a plant that can transport water, minerals and photosynthetic products throughout the plant. This wonderful plant actually has true roots and leaves to help it absorb nutrients from the earth, and true leaves to help contain water from evaporation and photosynthesize. These wondrous, leafy, plants are multicellular, photosynthetic and autotropic like most of it's green realatives. |
