### process:

Transpiration
* Most transpiration involves osmosis.
* Some transpiration contributes to constant rainfall
  - increases atmospheric humidity.
  * It happens because the plant opens its pores in order to get carbon dioxide gas from the air for photosynthesis. Transpiration also cools plants and enables the flow of mineral nutrients from roots to shoots
  - creates water demand in plants
* appears to be an adaptation that cools a plant.
* assists the plant in absorbing nutrients from the soil as soluble salts.
* can also indirectly reduce soil erosion by reducing streamflow during storms.
* depends on environmental factors
* evaporates the water into the air so that it can fall as rain.
* exerts a pull on the water column within the xylem.
* gives evaporation a bit of a hand in getting the water vapor back up into the air.
* happens when the sun warms the water inside the blade
  - water soaked up by plants evaporate into the air
* has effects.
* helps cool plants, but is also involved in moving nutrients from root to leaf.
* includes water evaporated from leaf and other plant surfaces.
* is an action
  - another important part of the water cycle
  - dependant on plant type, density of vegetation, growth stage
* is evaporation from the surface of plants
  - of liquid water from plants and trees into the atmosphere
  - like evaporation, but it occurs in living things like plants and animals
  - natural processes
  - relatively independent of body temperature, up to some point
  - simply the evaporation of water through plant membranes
  - term given to the loss of water from the shoot of the plant
* is the biological process that occurs mostly in the day
  - evaporation of vapor from a plant, especially the leaves
* is the evaporation of water from plant leaves
  - plant tissues into the atmosphere
  - stems, leaves, and other plant parts
  - the aerial parts of a plant
  - through plants
  - evaporation, or loss of water vapor, from the leaves
  - evaporative loss of water vapour from a land plant
  - event in which plants lose water vapor to the atmosphere
  - fancy name for how plants cool themselves
  - loss of oxygen through a plant's leaves
* is the loss of water from plants in the form of vapor
  - the leaves and stems of the plant
* is the loss of water vapor by plants
  - from the plant surface
  - via evaporation through pores on the stems and leaves of plants
  - main process of water movement within plant tissues
  - movement of water through a plant to the atmosphere
* is the process by which a plant loses water, primarily through leaf stomata
  - leaves regulate water loss
* is the process by which plants consume water
  - lose water out of their leaves
  - lose water, mainly from their leaves
  - return moisture to the air
  - water evaporates from a plant's leaves and stems
* is the process of water evaporation through the leaves
  - loss from plants through stomata
  - way plants use water to carry nutrients through their structure
* is when plants exchange water for carbon dioxide
  - water is taken from the living things like plants and animals
* moves amounts.
* occurs as long as stomates are open.
* occurs at same time
  - by way of the stomata of leaves
  - in leaves after being separated from the tree
  - mainly through a plant's stomates
  - more quickly at higher temperatures due to increased evaporation
  - mostly at stomata , tiny epidermal passageways of leaves and stems
  - when leaves use carbon dioxide to produce carbohydrates through photosynthesis
* plays several important roles in keeping the plant alive.
* pull theory is the proposed mechanism by which trees draw water through their roots.
* refers to the expiration of water through the minute pores or stomata of trees
  - process that plants use to cool themselves
* replaces oxygen and water vapor in the air.
* requires that liquid water evaporate, which has a cooling effect.
* takes place when water passes through the leaves of plants.
