Which of these cells in a plant are dead at maturity? Choose all that apply.
A. Phloem fibers
B. Guard cells
C. endodermis
D. Companion cells
E. Palisade mesophyll cells
F. Sieve tube elements
G. Pericycle cells
H. Xylem fibers
I. Xylem vessel elements
Homework Answers
A, H
Xylem has four components. Tracheids, vessels and xylem fibers are dead. Xylem parenchyma is alive.
Phloem has four components. Sieve tubes, sieve cells and albuminous cells are alive. Phloem fibers are dead.
Dead at maturity means the cells are not able to perform any metabolic function. They do not have Protoplasm. The cell wall is highly lignified.
