Summary

[edit]
Description
English: illustrated life cycle of Polytrichum sp.

1) the sporophyte 2) the spores 3) the spores germinate into a protonema 4) antheridia 5) archegonia

6) fertilization
Čeština: kreslený životní cyklus ploníku

1) sporofyt – štět s tobolkou 2) výtrusy 3) z výtrusů vyklíčí prvoklíček 4) samčí pohlavní orgány – antheridia = pelatky 5) samičí pohlavní orgány – archegonia = zárodečníky 6) díky splynutí pohlavních buněk může opět vzniknout štět s tobolkou

Pokud se tento obrázek rozhodnete použít ve škole, ne abyste po dětech chtěli, aby se životní cyklus učily nazpaměť… Za rozumné však považuji dát jim nějaká tvrzení, jejichž (ne)pravdivost mohou ze schématu vyčíst, např. „před vytvořením štětu s tobolkou musí dojít ke splynutí pohlavních buněk“, „mech se rozmnožuje pomocí semen“ apod.
