Primary root (taproot) - Fleshy, long single root,
that grows straight down
Stores food
Fibrous root system - Slender roots and lateral
branches
Anchors plant to soil
Adventitous roots - Roots develop from organs of
the shoot system
Prop roots & Climbing roots

Haustoria:
Rootlike projections that grow into host plant
Make contact with vascular tissue and extract
water and nutrients
Mycorrhizas:
Associations between roots and fungi
Assist in water and mineral extraction
Root nodules - Contain nitrogen-fixing bacteria
