Which among the following sets of pteridophytes are characterized by the production of two distinct spore types?
Salvinia and Selaginella
Psilotum and Equisetum
Adiantum and Pteris
Lycopodium and Dryopteris
Given below are two statements : One labelled as Assertion A and the other labelled as Reason R:
Assertion A : The initial phase of the gametophyte in the moss life cycle is the protonema stage.
Reason R : Protonema arises directly from spores liberated from the capsule.
In the light of the above statements, choose the most appropriate answer from options given below:
Both A and R are true and R is the correct explanation of A
Both A and R are true but R is NOT the correct explanation of A
A is true but R is false
A is false but R is true
Which structure represents the first stage of the gametophyte generation in the moss life cycle, developing directly from a germinated spore?
Protonema
Capsule
Sporophyte
Gametophore
In the life cycle of mosses, the spore directly develops into a branched, filamentous structure called:
Prothallus
Protonema
Sporangium
Antheridium
What is the immediate product of spore germination in the moss life cycle?
Capsule
Protonema
Sporophyte
Rhizoid
