soil that plant needs to produce food. Some plants have taproots (A). A taproot is the main root
that goes deep into the soil. Some plants have fibrous roots (B). Fibrous roots have same size
and grow long but not deep. Fibrous roots have root hairs that take in water and nutrients from soil.
Other plants like most trees have creeping roots(C). These roots are hard, not so deep and
spread away from plants. Others have tuberous roots (D). Tuberous roots are very thick roots.
