How can the saguaro cactus take up so much water?

Cactus plants have their roots a few inches below the ground to help them absorb as much water as possible. Their roots are shallow and widely spread to enable them to collect water even from light rains. What is this? These plants also develop some temporary roots that absorb extra water during rainy days.

How does a saguaro cactus soak up so much water in such a small amount of time?

Watering Technique

Saguaro cactus roots are located near the surface of the soil. This enables them to soak up even small amounts of rainfall. Because the roots are close to the soil surface, watering a saguaro cactus isn’t the same as watering other plants.

How do saguaro cactus absorb water?

Saguaros have a smooth and waxy skin which surrounds its tall, columnar stem in a vertically ribbed fashion. This in return allows the cactus to absorb large amounts of water, that is, when water is available. As the cacti absorb this water, the outer pulp expands like an accordion.

How does the saguaro cactus hold large amounts of water?

The interior of the cactus is filled with a sponge-like tissue, which is used to hold the water. As more and more water gets stored, the skin of the cactus begins to expand, making room for more storage. As a result, the saguaro cactus can become quite heavy as more and more water is stored.

Why do cactus have thorns?

Over time, those leaves evolved into the spiky spines we see on cactuses today because they help the plants survive in hot, dry environments. “They can be a defense mechanism to discourage herbivores – animals that eat plants – from eating the cactus. But, also, spines create shade!” explains Kimberlie McCue.
