Hi! I got two aquatic plants and I am hoping you can help tell me what they are.

Plant 1. This plant has like long green etensions and smaller versions of itself coming off it. I planted the "main" plant and the smaller attached ones are floating, but they have roots coming off. Should I plant the "extensions" too? They are connected to the main plant by long green grass ropes/vines.

This is the other plant, plant 2.

Thanks for the help if anyone knows what they are and if I should also plant the "babies" the one main plant has.
