The image is a photograph of a sign in a store. The sign is white with black text and a logo on the top left corner. The text on the sign reads "Physical defense systems: tricky weapons". Below the text, there is a list of different types of weapons used in physical defense systems. 

The list includes:

- Many plants use several techniques to arm themselves against herbicide-vores. One technique is the secret of a waxy coating, which serves as a physical barrier that protects plants from bacterial and fungal diseases.

On the right side of the sign, there are illustrations of a wooden spoon and a fork. The background is blurred, but it appears to be a store with other items on display.
