Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Damaging the bark of a tree is bad for the tree for all the the following reasons EXCEPT ____
A
bark protects the tree from pathogens
B
damaged cambium, which is just under the bark, could prevent future growth
C
doing so could damage the phloem and affect sugar transport
D
xylem, which is just under the bark, won’t be able to transport water
Explanation: 

Detailed explanation-1: -Dead phloem tissue becomes the bark of a tree. The band of tissue just inside of the cambium is the xylem, which transports water from the roots to the crown. Dead xylem tissue forms the heartwood, or the wood we use for many different purposes.

Detailed explanation-2: -Secondary xylem also known as wood is produced by the vascular cambium layer of cells. Bark comprises all the tissues external to the vascular cambium, therefore, secondary xylem is not present in the bark.
