- CSalvinia, Selaginella and Azolla show heterospory.
- DThe genome of TMV is RNA.
Correct answer
B. Cyanobacteria form mycorrhizae which helps in the absorption of phosphate
Step-by-step solution
"Myco" - "rhiza" literally means "fungus" - "root" and describes the mutually beneficial relationship between the plant and root fungus. These specialized fungi colonize plant roots in a symbiotic manner and extend far into the soil. Mycorrhizal fungal filaments in the soil are truly extensions of root systems and are more effective in nutrient and water absorption than the roots themselves. Cyanobacteria on the other hand is not a fungus.
