Question
Bryophytes have all of the following characteristics excepta) multicellularityb) lignified vascular tissuec) specialised cells and tissuesd) a reduced, dependent sporophyt
Solution
The correct answer is b) lignified vascular tissue.
Bryophytes, which include mosses, liverworts, and hornworts, are indeed multicellular (a) and have specialized cells and tissues (c). They also have a reduced, dependent sporophyte (d). However, they do not have lignified vascular tissue (b).
Vascular tissue, which includes xylem and phloem, is a characteristic of vascular plants, not bryophytes. The xylem helps with water transport and the phloem with nutrient transport. Lignin is a complex organic polymer that hardens and strengthens the cell walls of vascular plants. Bryophytes, lacking these, are non-vascular plants that absorb water and nutrients directly from their surroundings.
