"Sixth" sense? So what are a plant's other 5 senses?

Probably chemical particles in the air. Plant roots are designed to seek out nutrient particles in the soil, so detecting similar particles in the air is but a small step.

Chloroplasts. How else would plants "know" which way to turn toward the sun? Seeking darkness is common in the seedling stages of many climbing aroids.

It didn't have to, any more than a lichen-mimic moth needs to know it looks like lichen. In the case of the moth, start with a population of variously-colored moths who instinctively rest on lichen-covered tree trunks; then, those who happen to look most like lichens would be the survivors. In the case of the plant, the same general principle operates.
