yes.
roots
No.You plant the bulb of the onion underground and it grows and when it is ready the onion will be above the ground, but the roots will still be underneath.
Roots modified to perform some special function such as climbing or storage
Plants usually store food in their fruits and seeds such as many crop plants like wheat, pea, pegion pea etc; in the stem tubers like potato or in roots like sweet potato. Whether they store their food in roots or fruits depends on the plant.

examples of plants with modified roots.....
There are many things a plants roots do for an ecosystem. Plants roots help prevent erosion of soil for example.

If you are being strict about "plant", then yes. For example seaweed is an algae, not a plant - it doesn't have roots. Some plants have very reduced roots, mosses for example.
Onion roots emerge from the base of the condensed stem.
To adapt to the environment they are in.Example:Some cacti have their roots deep in the ground, to get groundwater.Some cacti have their roots spread out, to catch rainwater. Their roots also secrete an acid that makes it difficult for other plants (including other cacti) to grow on those roots. This limits the competition for water.

Cactus plants hold water temporarily in their roots. They also hold it temporarily on their modified leaves. They hold it permanently in their stems.
Modified roots are roots which change their structures to carry out vital functions such as photosynthesis, gather oxygen, store food or water, or support the stem.BIBLIOGRAPHY FROM URL:http://www.tutorvista.com/biology/modified-rootsHoped I helped!
Many plants do not have seeds- for example, the Aspen tree, which spreads by roots, most hosta plants (also spread by roots), and many ferns (spread by spores).
Carrots, Potatoes, Beets,
Legumes do. Peas are a good example.
