Question

Basic difference between vessel and Tracheid is
A. Types of pits
B. Thickness and lignifications
C. Perforations of end walls
D. Function

Answer 1

Hint:
They both play a role in water and mineral conduction in plants. Although they both perform the same type of functions, yet they strikingly differ from each other as the structure of cells is different for both of them.

Complete answer:
The basic difference between vessel and tracheid is the Perforations of end walls. So, option C is correct.
Now, let’s have a view at the terms vessel and Tracheid.
Food, supplements, water, minerals are moved from roots to leaves by two kinds of vascular tissues, viz, xylem and phloem.
Xylem tissue transports water and minerals from roots to different pieces of the plants, with the assistance of tracheids and vessels. These Xylem tissues are otherwise called tracheary components.
They both are dead cells at maturity and they possess a secondary lignified cell wall.
But there are certain points of differences between Vessels and Tracheid.

Additional information: The vessels are made by piling up of many cells .ie. Syncyte. The tracheid is made of individual cells .ie. not syncyte.

Note: The vessels are made up of perforated end walls which aids them in acquiring a tube-like long structure but the tracheids are devoid of perforations. So, the similarities and dissimilarities between the two of them should be kept in mind.
