Will these propagate? 🥹

Hey all, VERY big noob to plants but have become obsessed and been lurking multiple subs for the past week for 10 hours a day

1 I found a big monstera that was dead/no leaves just 1 big stalk – I cut a chunk of the stem off with hopes of regrowing it, will this work or do I need some sort of node etc?

1. Same question for a leaf that fell off an alocasia elephant ear – does it need more/a node or will this work? Bottom of it is firm

If you need any more info please ask – hoping for this sub to become my new second home 😀

Thanks!!
