Fun Paper Friday

This week's Fun Paper Friday features a study on the leaf-mimicking abilities of Boquila trifoliolata. The vine is capable of changing the shape and size of its leaves to resemble those of neighboring plants, potentially as a form of camouflage against herbivores. But the most surprising part? It can even mimic artificial plastic leaves. This finding challenges existing theories that leaf mimicry is driven solely by chemical signaling or genetic exchange between plants, suggesting instead that Boquila may possess a form of plant vision through specialized light-sensitive cells called “plant ocelli.” This discovery opens new possibilities for understanding plant sensory and adaptive behaviors.
