Tentacles in Plants
In carnivorous plants, tentacles refer to the stalked glands of the upper surface of the leaves.
On a sundew plant, they are hairlike projections with a drop of nectar-like glue which attract insects. When an insect is captured, the tentacles bend inward and the leaf rolls together as shown in the picture. The tentacles then secrete enzymes to dissolve and digest the insect.
