diffrence between stomata and hydathodes.
Dear Student,
Hydathodes are special pore-like structures at the margins and tip of leaves of some grasses and angiosperms which secrete excess water in the form of liquid drops apart from transpiration.
The water also contains salts, sugars, and organic compounds dissolved in it and sometimes seen to crystallize on evaporation.
Stomata are tiny pores present on the epidermis of the leaves. They are surrounded by guard cells that regulate the opening and closing of the stomata. Stomata basically have two major functions:
1. Helps in photosynthesis by facilitating gaseous exchange. The absorb carbon dioxide and release oxygen.
2. Stomata also helps in transpiration.
