Bio 101 lab practicum
1. what is the most common tissue in young roots: Parenchyma
2. The water conducting tissue in plants is called...: Xylem
3. What is gravitropism?: a plants response to gravity by growing toward or away from gravity
4. What is the function of the root cap: protect apical meristem of the root
5. In what zone of the root are cells actively dividing?: Zone of division
6. What structure increases the surface area of roots for water absorption: Root
hairs
7. What zone are root hairs found in a longitdinal section of a root: zone of maturation
8. Ranunculus is a plant that lives for many years. Corn is an annual plant. Why
are there no starch grains in the cortex of the roots of Zea mays?: because Zea does
not store food because it does not overwinter.
1/5
, 9. Why might it be important for the root not to be moving through the soil
when there are root hairs developing?: Because root hairs are delicate and they would be ripped
off the root.
10. Label the diagram of the root tip below:
11. Label the cross section of the root:
12. Tendrils:
13. fibrous root: type of thin root that makes up a highly branched root system (no main root), in monocots
14. Palmate venation, lobed leaf margin:
