Question

In Bryopsida the rhizoids are
1. Multicellular and unbranched
2. Unicellular and unbranched
3. Multicellular and branched
4. Unicellular and branched

Answer 1

Correct Answer - Option 3 : Multicellular and branched

Concept:

• Bryophytes are small, non-vascular plants. They do not possess true roots, leaves, and stems
• They are amphibious in nature and are also called ''amphibians of the plant kingdom'' because these plants can live in soil but are dependent on water for sexual reproduction.
• Bryophytes can be categorized into three types Hepaticopsida or Liverworts, Anthoceropsida or Hornworts, and Bryopsida or mosses

​Explanation:

Bryopsida or Mosses:

• All the mosses are included in this group.
• The main plant body is differentiated into rhizoids, stem-like, and leaf-like structures
• The rhizoids found are multicellular and branched. These rhizoids possess oblique seta
• Examples of Bryopsida are Funaria (Rope moss), Andria (Granite moss), Polytrichum ( Hair cap moss)

• Rhizoids are the simple hair-like protuberances that extend from the lower epidermal cells of bryophytes.
