2. c. store food: tubers (potatoes, carrots, beets)
Functions:
a. anchor plants
b. absorb water
c. store food: tubers (potatoes, carrots, beets)
d. may produce runners which grow into new plants

3. 2. Structures:
Root Hairs- tiny hairs that absorb water and minerals
Cortex-bulk of root, transports water to vascular core
Parenchyma-makes up cortex, may act as storage
Vascular cylinder-xylem and phloem of the root
Endodermis-single cell layer that controls flow of water into vascular bundle
Apical Meristem-where growth occurs
Root cap- protective covering over end of root
