Teaching Plant Anatomy Through Creative Laboratory Exercises
Hydathodes usually occur along the margins or at the tips of leaves and are
characterized by abundant xylem leading to the hydathode, modified mesophyll
cells, and several stomata that remain open. A large hydathode, illustrating these
...

All three BEs have about average expression level in hydathode. Hydathode
permits the release of water through pores in the epidermis or margin of leaves,
and it is connected to the plant vascular system by a vascular bundle. However,

Each hydathode consists of a pore in epidermis followed by large intercellular
spaces, loosely arranged parenchyma and blindly ending xylem elements (
tracheids terminate below the air chamber). The loosely arranged mass of
parenchyma ...

At around the same time, subepidermal cells at the tip of the leaf differentiate to
form a hydathode and associated epithem (the subtending airspace). The
hydathode consists of a series of specialized stomata known as water pores that
allow ...

Fundamentals Of Botany:
Hydathode represents modified bundle-ends. Guttation liquid is not pure water
but a solution containing a great number of dissolved substances. The loss of
water in the form of vapour from the aerial parts of the plant is known as
transpiration.
