Why Doesn’t the Palo Verde Tree Need Water?

The video explores the unique adaptations of the Palo Verde tree, which thrives in arid regions like the American Southwest. Unlike succulents, it is a deciduous tree with small leaves that limit water loss. The tree performs photosynthesis through its green trunk and stems, allowing it to survive without leaves. It has deep roots and trichomes to capture and conserve water. However, its thin bark makes it vulnerable to wildfires, especially in areas with invasive grasses.

What characteristic allows the Palo Verde tree to thrive in arid environments where other trees might not survive?

• It grows only in wet areas.

• It has a bright green trunk and stems for photosynthesis.

• It stores water in its trunk like a cactus.

• It has large leaves to capture more sunlight.

How do the small leaves of the Palo Verde tree help it conserve water?

• They provide shade to the trunk.

• They reduce water loss by limiting transpiration.

• They allow the tree to store more water.

• They increase the rate of transpiration.

What is the primary function of the Palo Verde tree's green trunk and stems?

• To store nutrients for the tree.

• To perform photosynthesis without leaves.

• To provide structural support.

• To protect the tree from predators.

Which adaptation helps the Palo Verde tree access water during dry periods?

• Its thick bark that retains moisture.

• Its deep roots that reach groundwater.

• Its ability to grow only during rainy seasons.

• Its ability to store water in its leaves.

What makes the Palo Verde tree more vulnerable to wildfires?

• Its thick bark that traps heat.

• Its shallow roots that catch fire easily.

• Its thin bark that offers little protection.

• Its large leaves that dry out quickly.
