6. Leaves and Water
 Leaves pull water
and minerals
through the plant.
 Water and
minerals are taken
in at the plant’s
roots and pulled up
the stem to every

9. Leaves and Branches
 As a plant gets bigger
it needs more food and
more air, so it must
grow more leaves.
 It grows more
branches so that the
leaves are spread out
and do not shade each
other.
