Question

The water conducting tissue in Bryophyta is

• A. Parenchyma
• B. Sclerenchyma
• C. Trachieds
• D. Sieve tubes

Answer 1

The correct option is A Parenchyma

Stems in mosses are multicellular and can show a surprising amount of tissue differentiation depending on the species of moss. Typically, most mosses have cortical cells (also called parenchyma cells), that compose much of the stem, and thick walled cells called as stereids for structural support. Some mosses have internal conducting strands, that guide water and even metabolites through the stem. In general the cells that conduct water are called as hydroids and cells that conduct metabolites are called as leptoids. A leptoid is a type of elongated food-conducting cell in the stems of some mosses, which surround strands of water-conducting hydroids.

Hence the correct option is A.
