Fact 1: Plants that are adapted to very dry environments are called xerophytes.

Fact 2: Plants that have adapted by altering their physical structure are called xerophytes .

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