The most common structure for vegetative propagation in Lichens is __________.
The most common structure for vegetative propagation in Lichens is __________.
Show Hint
Think of the tiny powdery granules that dust off a lichen thallus.
Updated On: Jul 4, 2026
- bulbils
- soredia
- cephalodia
- pycnidia
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Lichens, being a symbiosis of fungus and alga, reproduce vegetatively by releasing small propagules that already contain both partners.
Step 2: The most common of these are soredia, tiny powdery granules made of a few algal cells wrapped in fungal hyphae, which break off and disperse to start new lichen thalli elsewhere.
Step 3: Cephalodia are patches containing a different photobiont, pycnidia are fungal fruiting structures, and bulbils are not typical lichen structures, so option (B) soredia is correct.
