FAQ
Frequently Asked Questions
No. Stomata are pores for gas exchange (CO2 in, O2 and water vapor out) and have guard cells that open and close. Hydathodes are pores for liquid water secretion (guttation) and typically lack guard cells.
The water droplets formed by guttation are easily visible. However, the hydathode pore itself is microscopic and requires magnification to see clearly.
No. Hydathodes are common in many herbaceous plants (e.g., grasses, strawberries, tomatoes) and some tropical plants, but not all plant species possess them.
No. Dew is atmospheric water vapor condensing on a cold surface. Guttation is liquid water actively secreted from inside the plant through hydathodes.
A specialized pore or structure in the leaves of some plants that exudes water in a process called guttation.
