Solution
Verified by Toppr

Tyloses are the balloon-shaped extension of xylem parenchyma cells of vessels in the heartwood. These structures are mostly found in drought exposed plants or in infected plants wherein they serve to reduce the surface available for transport in the conducting element and thereby acting as morphological defenses.
Therefore, the correct answer is option A.
