What is the liquid on the sundew?

The liquid on the sundew plant is a sugary, mucilaginous secretion produced by glandular hairs called trichomes on its leaves. This sticky substance attracts and traps insects, which are then digested by the plant to absorb nutrients. The liquid serves both as a lure and as a means of digestion, enhancing the sundew's ability to thrive in nutrient-poor environments.
