You are presented with the question "What do Xerophytes do to adapt to dry environments?" and the following answer choices: 
- By wind and rain
 - The flowers are pollinated
 - photosynthesis.
 - Transfers energy
 - To conserve energy
 - alter their physical structure
 - thermal insulators
 - hydrate their cells

Now knowing that plants that are adapted to very dry environments are called xerophytes and plants that have adapted by altering their physical structure are called xerophytes , choose the best answer.


 

      alter their physical structure
