Encourage the students to explain the functions of each part, filling in details from the Saguaro Parts and Their Functions chart below. Write the name next to each part as the group discusses it. · What are they for? (They allow the cactus to swell and take in water, or shrink as the water is used.) · What do they do for the cactus?
An important diference between naturally occurring saguaro and planted saguaro can exist in the root system. Saguaro roots may have been severely trimmed during transplanting. Poor planting and inefective establishment techniques are challenges for transplanted saguaro.
The xylem vessels transport water from the roots. Phloem facilitates the transfer of sugars throughout the plant. As plants age, the vascular tissue produces wood. Drawing shows four common cacti of the Sonoran desert: Cholla, Saguaro, Prickly Pear, Barrel Cactus.
Though they’re about 30 inches across, their root systems can extend as far as 100 feet (or as wide as three school buses parked in a line). These majestic cactuses can live up to 200 years. They develop their upturned arms (as many as 24!) at 75 to 100 years of age.
The saguaro (suh-waa-row), also known as the giant cactus, has been an iconic symbol of the American southwest for ages. These majestic beings are easily recognized by their size and structure, sometimes reaching a height of 50 feet tall.
Gray spines densely cover the stem. The funnelform-campanulate flowers are 8.5-12.5 cm and the outer parts are green with lighter borders and the inner parts are petal-like and white. The nocturnal flowers appear singly at the uppermost areoles and they smell like ripe melons. When open, each flower is filled with many white stamens.
4 Μαρ 2022 · We assess phylogenetic structure across the geographic range of the saguaro cactus, an emblematic member of Cactaceae, a clade known for extensive hybridization and porous species boundaries.
