The Touch-Me-Not plant is a small plant whose leaves close and droop when you touch them.

Its science name is Mimosa pudica.

👀 What happens when you touch it?

• The leaves fold inward
• The stem may bend down
• After some time, the leaves open again

(thigmo = touch, nasty = movement)

⚙️ How does it work? (Simple science)

Inside the plant:

• There are tiny cells filled with water
• When touched, water moves away quickly
• Cells lose pressure → leaves collapse

🧠 No muscles, no brain — just smart plant cells!

🛡️ Why does the plant do this?

The leaf-closing helps the plant:

• Scare away insects 🐜
