Solution

Water droplets were seen as a result of guttation. Guttation is the loss of water in the liquid state from uninjured parts of plants, usually from tips and margins of leaves. In this, water exudes from the group of leaf cells called hydathodes. A hydathode is an opening or pore in the leaf epidermis, around, which are grouped as several thin-walled parenchyma cells. It occurs during the night or early morning when there is high atmospheric humidity and transpiration is less.
