|
Guttation only occurs in the margins of plants that have broad, fleshy leaves
|
|
Hydathodes in trees or large woody plants are located along seams or folds in the outer bark
|
|
Root pressure is not strong enough to push water up through trees or large woody plants
|
|
Trees or large woody plants are gymnosperms, unlike angiosperms that have evolved guttation
|
Detailed explanation-1: -Since the guttation process relies on pressure to push water upward through the plant’s stem and leaves, it cannot occur in larger plants such as trees because the required amount of pressure would be much too demanding.
Detailed explanation-2: -The process of loss of water in the form of liquid drops from the edges of leaves or the tips of veins through hydathodes is known as guttation. This process usually happens in herbaceous plants when the humidity is and the root pressure is high and the rate of transpiration is low.
Detailed explanation-3: -Guttation is the loss of water (in the liquid phase) from the surface. As a result, root pressure causes a positive pressure to be formed in the xylem, causing the guttation process to occur.
