Lignin supports. the stems of ___ .

  1. a. mosses
  2. b. hornworts
  3. c. ferns
  4. d. liverworts

Summary Introduction

Introduction: Lignin is a natural polymer found in plant cell walls. Lignin and cellulose both function together and provide structural support to the plants. Lignin is hydrophilic and allows the transport of water in the vascular tissues through tracheal elements. It is present in the walls of xylem cells. This helps the vascular plants to stand tall and branch further.

Explanation of Solution

Reason for the correct statement:

Ferns are the diverse seedless vascular plants. The vascular plants consist of lignin present in their secondary cells walls. They provide the structural support to the plant by enabling tracheary elements in xylem cells to stand the tension generated during the water transportation. The interconnected vascular strands in the stems provide rigidity and stiffness to maintain their verticality.

Hence, option c. is correct.

Reasons for the incorrect statement:

Option a. is given as “mosses”...
