When Plants Give Off Drops of Water It Is Called

When plants give off drops of water, it is called guttation. Guttation is the process where excess water and dissolved minerals are excreted in the form of small droplets through plant leaves or stems. This event is not to be confused with transpiration, which is the process where water evaporates from the surfaces of plant leaves and stems.

The Science of Guttation

Guttation occurs when internal pressure inside plant cells increases due to the absorption of water through the plant roots. The absorbed water is then transported upwards, and excess water accumulates in the plant vessels in the absence of transpiration. The water is then forced out of the plant through specialized structures called hydathodes. The hydathodes are openings along the leaves' edges that allow water droplets to be excreted.

When Does Guttation Occur?

Guttation primarily occurs during the night or early mornings when humidity levels are high, and soil moisture level is adequate. Guttation is often observed in young plants that have not developed a well-established root system. In such plants, guttation may occur frequently as they try to cope with the stress of absorbing excess water.

The Significance of Guttation

Guttation has several benefits for plants. First, it helps to reduce the risk of water stress in plants by preventing excess water from building up inside plant tissues. Second, guttation provides an alternative mechanism for the transport of minerals and nutrients to other parts of the plant. This is especially beneficial for young plants that may not have developed a well-established root system yet.

The Risks of Guttation

While guttation has several benefits for plants, it can also pose risks. Excessive guttation may cause plant tissues to become wet, creating a favorable environment for the growth of fungal diseases. Furthermore, guttation may release soluble salts, which can accumulate on the surface of leaves and damage plant tissues.

Conclusion

In summary, guttation is an essential process that occurs in plants to regulate water levels and transport nutrients. It is a necessary process that serves to protect plants from water stress and transport minerals through the plant. However, excessive guttation can lead to the spread of fungal diseases and harm to plant tissues. Therefore, it is essential to balance guttation with appropriate plant care and pest management practices.
