can someone help me with these terms for plants
Propagation i am assuming this is reporduction

I do not know what these terms mean when it comes to plants(adventitous and rhizome)i am assuming they have something to do with reproduction, but i would like to know how to make new plants with the plants that i already have and i understand that most of them use these two forms of propagation from what i have read. I know that sounds a little confusing so if you have any questions please ask. Thanks
