Adaptations
Roots
• The purpose of the roots is to
hold the plant in the ground
and to draw water from the
soil.
Why do trees have strong roots?
• Would an adult tree be able to
survive with roots like the ones
below?
Why do cacti have shallow roots?
Water lilies have long roots. Why do
water lilies have long roots?
What is the purpose of the dandelion’s
large thick root?
Stems
• The purposes of the stem are to
keep the plant upright and
bending toward the sun, and to
move water throughout the
plant.
• Some stems also provide
protection for the plant.
Vines have stems that can climb up the
house. Why are the vines climbing the
house?
Why do trees have strong stems?
Cacti have thick stems that store water
when the habitat does not provide it.
What would happen if cacti
had thin stems?
Cause
If cacti had
thin stems…
Effect
Why do some
stems have thorns?
Leaves
• The purpose of leaves is to
produce food for the plants.
• The leaves absorb the light for
the sun.
• Leaves come in all different sizes,
textures, thicknesses, and shapes.
Why do water lilies have wide leaves?
Evergreen trees have leaves that are
thin waxy needles to protect them
from freezing and losing water.
Flowers
• The purpose of flowers is to attract
organisms, such as birds and insects,
for pollination.
• Pollination is the spreading of pollen
from one flower to another.
• Flowers come in different sizes,
colors, and smells.
Why do plants
produce different
types of flowers?
Fruit
• The purpose of the fruit is to
protect the seeds.
• Not all plants grow fruits.
Some plants grow cones that
protect the seeds.
Some fruits are moist and fleshy.
Fleshy fruits attract animals that eat
them helping to disperse the seeds.
Some fruits are dry and/or hard.
Seeds
• The purpose of seeds is to grow new
plants.
• Some seeds begin to grow as soon as
conditions allow for germination.
• Seeds have adaptations that allow
them to be dispersed and also to
have enough food for the plant until
it begins to make its own food.
Seeds grow into new plants.
