Plant learned about it forgot the name???

Question

My mom brought home this plant that has leaves that fan out like a fern but are tiny and when touched they close up toward the middle and the branch falls to the ground. I used to know what they were called but can't for the life of me remember what they are called.

Answer 1

Mimosa, probably.  Also known as "sensitive plant".  Here's a picture; does it look familiar?
