In which of the following gametophyte is not independent free living?
Marchantia
Pteris
Pinus
Funaria
Correct answer: Pinus
Solution
In Pinus, the gametophyte is highly reduced and remains dependent on the sporophyte for nutrition and protection, so it is not free-living. Marchantia, Pteris, and Funaria all have independent, free-living gametophytes.
