Food Storage Roots Most roots store some
food
Some are enlarged to store starch and other carbohydrates
Examples: sweet potato, carrot, beet, radish

Extend above the surface of water
for plants that grow in swampy areas
Helps roots exchange gases
Example: Mangrove
Pneumatophores

Roots that occur above the surface of the soil Examples: prop roots in corn (support in high
wind)

Peg-like projections penetrate
host’s stem Usually in plants that do not
contain chlorophyll (can’t make food)
Examples: pinedrops, dodder (one organisms benefits, one is
harmed)

Huge roots near base of
trunk Usually in trees that grow in
shallow soil Rainforest environmentsExample: many tropical trees
