Your Answer
A
Psilotum
Your Answer
B
Adiantum
Your Answer
C
Equisetum
Correct Answer
D
Salvinia

Solution

The correct option is D Salvinia
Within the sporangia, the spore mother cell undergoes meiosis to form spores. If all the spores are of the same kind the plant is said to be homosporous (Lycopodium, Psilotum, Adiantum, Equisetum and Dryopteris), and if they are of two different kinds (macro and micro), the plant is called heterosporous (Selaginella, Isoetes, Marsilea, Azolla and Salvinia).
