Overview of Drosera tentacles in TEM: the gland head is formed by an outer and inner layer of secretory cells (outer gland cells, OGC; inner gland cells, IGC). They are supported by a bell-shaped layer of endodermoid cells (EC) that curve out to the surface at the base of the head. They surround the core of tracheids (Tr) and connect to the stalk by a ring of epidermal and parenchymal neck cells (ENC; PNC). These neck cells are continuous with the cells of the tentacle stalk, the epidermal and parenchymal stalk cells (ESC; PSV). Transfer of substances from the glandular cells to the stalk is provided by plasmodesmata between glandular cells, endodermis, neck cells, and tentacle stalk
