Hello!

I am a bit confused by the liverwort gemma and the moss spores... how are they different?
:confused:

Thanks!

I am afraid we might get a question like that on the exam, since so many things can be compared.
I know that the gemma allows for asexual reproduction, and that it needs water for asexual reproduction...
But I feel that I'm still missing something...

Thank you!
 
I believe gemma are produced by the gametophyte generation (haploid) and combine to grow into diploid organisms, while spores are produced by the sporophyte generation (diploid) and grow into the gametophyte.
