Difference Between Transpiration and Guttation
|
Transpiration |
Guttation |
---|---|---|
Working Mechanism | The mechanism through which plants lose water by evaporating it through their leaves’ stomata. | The process by which plants release excess water droplets from specialized structures called hydathodes located at the tips or edges of leaves. |
Duration | Occurs throughout the day and helps the plant’s internal water and nutrient flow. | Occurs during the early morning hours or at night when the soil is moist and the plant has taken in more water than it needs. |
Uses | Facilitates plant cooling. | Helps to remove excess minerals and other substances from the plant. |
The Reason Behind the Process | Releases water vapor into the air for re-absorption by the plant or other adjacent plants, which aids in the plant’s water conservation. | Can be a sign of overwatering. |
Contribution | It helps the plant’s internal water and nutrient flow. | Can contribute to water loss from the soil |
Difference Between Transpiration And Guttation
Plants employ two distinct processes namely transpiration and guttation, to regulate water balance within their structures. Transpiration involves the loss of water through tiny pores on leaves, stems, and other parts of the plant, which is essential for the uptake of nutrients and maintenance of cell pressure. Conversely, guttation occurs mainly at night or in the early morning and involves the release of water droplets from hydathodes, which are specialized structures at the tips of leaves or edges of petals, and is driven by root pressure rather than transpiration. Therefore, comprehending the difference between these processes is crucial for understanding how plants regulate water balance.
