Desert cactus, roots, stem and needles

1. DESERT CACTUS

2. What is a Cactus?
They are plants
that live in dry
regions.

3. Roots
-Long: lie close to
the surface of
the ground so
they can catch
water from
desert rains.
-Cork-like bark:
to absorb the
water quickly.

4. Stem
-No leaves: instead the stem does the job of
making food for the plant and storing its
water.
-Grow upward: so not too much of the plant
faces the rays of the sun.

5. Needles
-Sharp and pointed: to keep desert animals
from sucking out the water.
