Barrel Cactus
Ferocactus cylindraceus
• Barrel cacti live in warm desert environments
of North America.
Barrel Cactus
Ferocactus cylindraceus
• These cacti live in desert
environment where there is
plenty of sun so photosynthesis is
easy– leaves have adapted to
serve a different function.
• Most of the photosynthesis in
these plants occurs in the
enlarged stem or barrel itself.
• Spines are modified leaves that
provide protection from
predation.
Barrel Cactus
Ferocactus cylindraceus
• These cacti are adapted to
gather and store water.
• Unlike most desert plants,
cacti do not have deep root
systems.
• Instead, they spread their
roots out at the surface to
catch rain water.

• Once they gather the
water, they store it in
their thick stem or
trunk.
• Folds in the trunk
allow these plants to
expand and contract as
water becomes more
or less avaliable.
