select correct option of haploid structures of a bryophyte 
1 . capsule 
2 . seta
3 . gemma and foot 
4 . protonema 

Dear Student,

The spore was haploid and so are the resulting protonema. A bryophyte spore germinates and produces an often algal-like mat, called a protonema and the leafy or thalloid stage of the gametophyte develops from the protonemal stage. Hence option 4 is correct. 

Regards.
