Therefore the cause of the phenomenon of transpiration seems to be referrible entirely to physical agents.
The greatest factor, however, is transpiration of water from leaves.
This greater degree of transpiration renders them more tolerant of heat, and less of cold than the whites.
Evaporation of water from green leaf, regulation of transpiration.
Small passages should likewise be left throughout the body of the work, for the transpiration of moisture.
Why, madam, a blow like this would set a frog into a transpiration.
It is commonly said that there is a great difference between the transpiration and evaporation of water in plants.
With the cutting off of the water supply at the roots in late fall, transpiration is also cut off.
M. Leclerc has very carefully examined this question, and he concludes that transpiration is only the simple evaporation of water.
And, although an elevated temperature be favourable to transpiration, its modifying influence is less than that of other causes.
transpiration tran·spi·ra·tion (trān'spə-rā'shən)
The passage of watery vapor through the skin or through any membrane or pore.
The process of giving off vapor containing water and waste products, especially through the stomata on leaves or the pores of the skin.
Our Living Language : Plants need much more water than animals do. But why? Plants use water not only to carry nutrients throughout their tissues, but also to exchange gases with the air in the process known as transpiration. Air, which contains the carbon dioxide that plant cells need for photosynthesis, enters the plant mainly through the stomata (tiny holes under its leaves). The air travels through tiny spaces in the leaf tissue to the cells that conduct photosynthesis. These cells are coated with a thin layer of water. The cell walls do not permit gases to pass through them, but the carbon dioxide can move across the cell walls by dissolving in the water on their surface. The cells remove the carbon dioxide from the water and use the same water to carry out oxygen, the main waste product of photosynthesis. All this mixing of water and air in transpiration, though, has one drawback: more than 90 percent of the water that a plant's roots suck up is lost by evaporation through the stomata. This is why a plant always needs water and why plants that live in dry climates, such as cacti, have reduced leaf surfaces from which less water can escape.
