Step-by-step explanation:
Cardon cactus plants grow in the deserts of Baja California and parts of Sonora in Mexico. They are also found in the southern parts of California and neighboring Arizona in the United States. These cacti thrive in their harsh desert environments due to several adaptations. They have shallow roots that can reach out far from the base of the stem to gather as much moisture as possible. The cacti also have a large stem that can store water, and thorns that protect the stem from thirsty animals.
