Plants alternation of generations

[nemzy]

okay so the plant has two life cycles:

the diploid stage - sporophyte
the haploid stage - gametophyte

but is the archegonium and antheridium diploid or haploid?

and is the protnema diploid or haploid?

thanks

Both the archegonia and antheridia are reproductive structures that form on the gametophye (so they have the same complement of chromosomes as the rest of that plant).

A protonema is an early stage in the development of a gametophyte (just like the archegonia and antheridia, they have the same complement of chromosomes as the rest of that plant).
