Which one of the following is heterosporous?
Equisetum
Dryopteris

C.
Salvinia
The sporophyte of pteridophyte produces meiospores inside sporangia. which may be homosporous (e.g.,) Adiantum, Dryopteris, Equisetum, etc.) or heterosporous (e.g., Salvinia, Selaginella, etc.)
Identify the wrong combination
Dryopteris → Rhizome
Cycas → Coralloid roots
Volvox → Colonial form
Marchantia →Pseudoelaters
