Chapter 22, Problem 5RQ
Summary Introduction
To enlist:
The structural adaptations necessary for the invasion of dry plants and also state which adaptations are possessed by nonvascular plants, ferns and by gymnosperm and
Introduction:
Adaptations are the special features that allow plants to survive in a particular area. Sometimes lack of specific adaptations makes very difficult for the plant to survive. Plant adapt certain features like the development of cuticle when the environment is very dry, opening and closing of stomata is governed by the level of water in the plant body.
