The balloon like protrusion into the tracheary elements that develop in heart wood and increases the durability of the wood is called:

A
Tyloses developing from the phloem parenchyma
B
Bulliform cells developing from epidermal cells
C
Bulliform cells developing from hypodermis
D
Tyloses developing from xylem parenchyma

Solution:

The balloon like protrusions develop into the tracheary elements from xylem parenchyma cells are called tyloses. Normally tyloses develop in the heart wood and increases the durability of the wood.
