Do plants sweat?

It's usually just a spot or two, and not very much but ill find a gathering of water on a few fan leaves. I've not done enough studying to know what this is, could someone explain please? Looks like excess from watering but its got to be something else. Plants are all very healthy.

I see that now and again too. Sap or something pooled on a leaf or stem, right? Don't know what causes it, but do know it's nothing I'd be concerned about (although I was the first couple times I saw it).

...here you go guys.

Transpiration is a process similar to evaporation. It is a part of the water cycle, and it is the loss of water vapor from parts of plants (similar to sweating), especially in leaves but also in stems, flowers and roots. Leaf surfaces are dotted with openings which are collectively called stomata, and in most plants they are more numerous on the undersides of the foliage. The stoma are bordered by guard cells (together known as stomatal complex) that open and close the pore.[SUP][1][/SUP] Leaf transpiration occurs through stomata, and can be thought of as a necessary "cost" associated with the opening of the stomata to allow the diffusion of carbon dioxide gas from the air for photosynthesis. Transpiration also cools plants, changes osmotic pressure of cells, and enables mass flow of mineral nutrients and water from roots to shoots.


here's a link to wikipedia with the full definition if you'd care to read it.

peace, bozo

Only when they hear the cops at the door.

Ha!! That makes sense. Here's a pic of it, you've got to zoom in.
