Transpiration and Guttation
Question 1: What is Transpiration?
Answer:
Transpiration is the process by which plants release water vapor into the atmosphere through tiny pores on their leaves called stomata. It is a crucial process for plants as it helps in regulating their internal water balance, nutrient uptake, and temperature.
Question 2: What Factors Affect Transpiration Rate?
Answer:
The transpiration rate is affected by several factors including temperature, humidity, wind speed, soil moisture, light intensity, and the size and number of stomata.
Question 3: How does Guttation differ from Transpiration?
Answer:
Guttation differs from transpiration in that it is the excretion of excess water from the plant rather than the release of water vapor. Guttation occurs when the plant is taking in more water than it can transpire, usually at night or early morning when the humidity is high and the soil is moist.
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.
