Saguaros of the Sonoran Desert and cactus adaptations
The text explains spines shade cacti and deter predators while a waxy skin protects from sun. Saguaros grow to 60 feet in the Sonoran Desert of Arizona and northern Mexico, start branching at 50 to 70 years, and produce white yellow or pink flowers. Cacti have areoles that house spines flowers and branches, with internal woody skeletons and expandable epidermis to store water.

Desert Cacti Support Wildlife and Native Uses
Cacti provide nectar for bats birds and insects aiding pollination and seed production. Fruits feed birds mammals and coyotes while larger birds nest in cacti. In extreme drought deer jackrabbits and bighorn sheep feed on cactus sap. Native Americans used cactus fruit for wine jelly syrup and candy. Prickly pear pads are edible after spine removal.
