Question

Answer

The hydathodes are made of a group of living cell with numerous intercellular spaces filled with water, but few or no chloroplast and represent modified bundle ends . Therefore , hydathodes are involved in the process of guttation, in which positive xylem pressure (due to root  pressure ) causes liquid to excude from the pores.

Answer

Hydathodes are the structures that discharge water from the interior of the leaf to its surface in a process called guttation.

Answer

**Guttation and Hydathodes**

**Introduction:**
Guttation is a process in plants where water droplets are exuded from the tips or edges of leaves. It occurs when the rate of water absorption by roots exceeds the rate of transpiration. Hydathodes, also known as water stomata or water pores, play a crucial role in this phenomenon.

**Hydathodes:**
Hydathodes are specialized structures found in the leaves of plants, particularly in the margins or tips of leaves. They are tiny pores or openings that allow the release of excess water from the plant. Hydathodes are composed of specialized cells that are capable of secreting water droplets.

**Guttation Process:**
Guttation occurs primarily during the night or early morning when the soil is moist and the atmospheric humidity is high. It is facilitated by the process of root pressure. When the root pressure is high, water is forced up through the xylem vessels and reaches the hydathodes. The excess water is then released through the hydathodes in the form of droplets.

**Role of Hydathodes in Guttation:**
Hydathodes are essential for the process of guttation. They serve as the exit points for excess water that the plant cannot transpire. When the root pressure is high and the stomata are closed, hydathodes provide an alternative route for water to leave the plant. They prevent the accumulation of excess water within the plant, which could potentially lead to cell damage or bursting.

**Other Functions:**
While guttation is the primary function associated with hydathodes, they also play a role in other processes such as:

1. **Water Balance:** Hydathodes help to maintain the water balance within the plant by releasing excess water during periods of high root pressure.
2. **Salt Excretion:** In some plants, hydathodes also help in excreting excess salts. The salt ions are transported to the hydathodes and are released along with the water droplets.
3. **Pathogen Defense:** Hydathodes can also play a role in defense against pathogens. They can secrete substances that are toxic to pathogens, limiting their growth and spread.

**Conclusion:**
Hydathodes are specialized structures in plants that have several functions, including the release of excess water during guttation. They serve as exit points for water that cannot be transpired through the stomata. Understanding the role of hydathodes helps in comprehending the physiological mechanisms that plants employ to maintain water balance and respond to environmental conditions.

Answer

Hydathodes are the specialized pores at vein endings. Each hydrathode is made up of group of loosely arranged achlorophyllous or colourless and parenchymatous cells called epithem. These cells help in absorbing a good percentage of inorganic and organic solutes present in the exudate. It helps in guttation and always remain open.

Answer

Hydathode is a pore found in the epidermis of the leaves of certain plants. They are used by the plant to secrete water under conditions in which transpiration is inhibited, for example, when the atmosphere is very humid. This process of water loss is called guttation.
