It support the plant
They attract pollinators
They suck up water and nutrients from the soil
An apple is an example
They are beautiful
They are hidden underground
They hold the plant steady in the ground
They protect the developing seeds of the plant
They take carbon dioxide from the air into the plant
They make seeds that will someday grow into new plant
It carries water, minerals and food between the roots, the leaves and flowers
They catch energy from sunlight
They are delicious
