Land Plants Complex multicellular organism that range in size from minute to MASSIVE. Adaptations of this type of plant include anatomical, physiological, and reproductive features. Waxy Cuticle Covers aerial portions of a plant, protects against water loss. Resides ON TOP of the epidermis. Stomata Used for gas exchanged, required for photosynthesis. Guard Cells surround this and can open or close it depending on environmental/chemical interactions. Antheridia Gametangia that produce SPER...
