WebBryophytes have stoma and a waxy cuticle on their body that helps protect them from dessication. A gametangia (layer of protective cells) surrounds the gametes and the embryo may be packaged in a waterproof spore that begins to grow when it encounters water. But still restricted to moist habitats: 1. No vascular tissues ...

WebAnswer (1 of 2): Hydrophytes are plants that grow submerged or partially submerged in water. The cuticle is a layer of tissue on the outside of most leaves and stems, and its primary function is to help the plant conserve moisture. The outermost layer of the cuticle is waxy, which effectively sea... We have already spent quite a bit of time considering the evolutionary tree of life and the three domains of life.
