The process of transpiration is when water moves through plants from the roots to the leaves, then changes to vapor as it leaves the plant. Transpiration cools the plant and also provides it with nutrients, carbon dioxide and water.
A single plant can transpire at different rates over the course of a day, depending on a number of factors, including temperature, relative humidity, wind and soil moisture. There are also species-specific differences, which can be broadly classified by the type of photosynthesis: C3, C4 or Crassula
Although both are methods by which liquid water transitions into a gas, evaporation describes the process in which heat changes standing water into water vapor, while transpiration refers to the process plants undertake that draws water from the ground and releases it into the air.
When wind movement around a given plant increases, the rate of transpiration is bound to increase. The wind movement causes a rapid replacement of moist air with drier air around the given plant, which is why the rate of transpiration inevitably increases.
Transpiration pull theory is the proposed mechanism by which trees draw water through their roots. Transpiration occurs when the leaves of a tree allow water to exit into the air by means of tiny holes called stomata. When the water exits the leaves, the combination of capillary action, cohesion and
When the relative humidity in a plant's environment rises, its rate of transpiration lowers, and a decrease in humidity causes the transpiration rate to rise. Air that is humid does not accept water vapor easily, and drier air makes it easier for a plant to release water by evaporation through the s
The water, or hydrologic, cycle has only a few basic steps, beginning with evaporation of the water in rivers, lakes and oceans into water vapor, which then condenses into clouds. When enough water vapor condenses in the clouds, it then turns into either liquid water or ice. This then falls back to
The water cycle, also known as the hydrologic cycle, describes the process of how water moves through Earth's environment. In general, water evaporates from oceans, then it condenses in the atmosphere as water vapor cools. When enough water gathers in clouds, it precipitates back to the Earth's surf
The water cycle is important because water sustains all life on Earth. Through a series of evaporation, transpiration, condensation, precipitation, infiltration, runoff, and other smaller processes, the water cycle keeps the Earth's water clean, distributes the water across the planet's surface, mai
The water cycle changes because cycles of day and night, the seasons and the movement of water in any of its forms changes its environment, specifically its temperature. As water in oceans or on surfaces gets warmer, it evaporates, and the resulting water vapor moves along with the wind, often risin
