Question

The diagram represents a process in plants. The setup was placed in bright sunlight. Answer the following question.
Explain the term guttation.

Answer 1

Guttation is the process by which excess water evaporates from the tips of veins in the leaf. Due to this, droplets of water are seen along the margins of leaves in the morning. This phenomenon is observed in plants growing in warm humid condition because humid environment affects transpiration while the roots continue to absorb water from the soil. This builds up a high hydrostatic pressure within the plant and guttation occurs.
