Sundew (Drosera) is an insectivorous plant. Here each leaf is covered by the glandular hair like tentacles on the upper surface. Each tentacle bears a reddish gland which secrets a viscous fluid that glitters like dew drops in sunlight. Insects, mistaken by the substance as honey, come in contact and get entangled. Tentacles bend upon the insect and leaf assumes cup-like structure in which the insect is trapped and digested.
