Answer:
Correct Answer: C
Solution:
The tracheids are different from vessels for having the presence of a pit pore.
Tracheids have larger pits in smaller numbers while vessels have small pits in larger numbers.
Both vessels and tracheids show the removal of lignin in the form of complete curved bands or in the form of diagonal rods of the ladder known as callosiform thickening.
