lab 20: Vegetative Plant Structures

lenticels

Function in gas exchange

Compare the origin of primary, secondary, and adventitious roots.

Primary comes from the radical of the embryo

Secondary comes from pericycles and adventitious roots.

Root hairs

Epidermal outgrowths for absorption in roots

cambium

Tissue where the phloem and xylem grow

pericycle

Produces the secondary or branch roots & the vascular cambium of root
