Diffusion does not require energy
Answer:
Basal meristems
Explanation:
Meristems are the portion of plants able to generate any kind of new tissues. Therefore, the way plants keep their meristems protected is related to climate adaptation.
Grasslands tend to be arid ecosystems, so grasses have developed basal meristems, meaning they spend the dry season very close or under soil, where water evaporates slowlier than above surface, until wet season allows meristems to generate new stems and leaves.
This disposition is also useful in cases of fire and grazing, which are also frecuent in grasslands.
