Answer 1

Guttation:

1. Guttation is the loss of water from hydathodes (small pores) on a small herbaceous plant's leaf margin in the form of water droplets.
2. Root pressure causes positive pressure to be created inside the xylem, resulting in guttation.
3. Guttation occurs when transpiration is low or non-existent and the humidity is high.
