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.Continue Reading
The rate of transpiration is dependent on a few different factors:
As the temperature increases, the transpiration rate goes up. The openings in the plant that release the vapor are called stoma, and when the temperature is warm, the stoma are open. Colder temperatures cause the stoma to close.
Because it is difficult for vapor to be released into damp air, the less humid it is, the higher the rate of transpiration.
Wind and air movement
The transpiration rate increases with increased air movement. One reason is because air movement is constantly bringing drier air close to the plant, which relates to relative humidity.
Soil and moisture availability
If the soil does not have enough water, the transpiration rate decreases.
Type of plant
The transpiration rate differs depending on the type of plant. Cacti, for example, conserve water and have low transpiration rates.
Plant growth is caused by water that is absorbed by the plant's roots and sunlight that spurs photosynthesis, which is the process of creating food for the plant. Plants also need space, time, clean air, healthy soil and nutrients to grow. The main ingredients that plants need are phosphorous, nitrogen and potassium.Full Answer >
Transpiration is the process in which a plant releases water vapor from its leaves into the surrounding air. The rate transpiration occurs varies widely based on the weather and soil conditions surrounding the plant.Full Answer >
The National Snow and Ice Data Center explains that different species of plants adapt to cold weather in a variety of ways, such as growing in forms that shed snow readily or by retaining dead leaves to help insulate the plant. Unlike birds and other animals that can migrate to avoid harsh winter weather, plants must find a way to cope with the cold temperatures without leaving.Full Answer >
Botanists identify plants according to key characteristics such as the area in which the plant is growing, the shape of the plant's leaves, the type of bark or lack of bark and the presence or lack of fruit and flowers. Plants are generally divided into six major groups: woodland, aquatic, grass-like, orchids, ferns and flowering non-woodland plants.Full Answer >
