What is the role of root hair in plants?
Extension of a single epidermal cell
What is the cortex in plant structure?
Packing tissue composed of spherical, unspecialized cells
What is the function of the endodermis?
A single layer of cells
What forms the xylem in the vascular cambium?
Dividing cells
What are the components of the vascular cambium?
Constantly dividing cells between xylem and phloem
What are xylem vessels primarily composed of?
Long, narrow, hollow tubes formed from columns of elongated cells
What happens to the contents of xylem cells as they mature?
The contents die and the cross walls breakdown
What is the role of lignin in xylem vessels?
Thickens the walls and provides support
How does water move through a flowering plant?
By a combination of root pressure, transpiration, and capillarity
True or False: Xylem vessels are living cells.
False
What is the function of cork cambium?
