Detailed explanation-1: -Plants lose water in the liquid form through the process of guttation and bleeding. Guttation exudes water through pores called hydathodes. Bleeding happens through the cut surface of plants. Transpiration is the loss of water vapor from the aerial parts of the plant.

Detailed explanation-2: -Guttation is the loss of water in solution form through hydathodes. It occurs under the influence of root pressure. When transpiration is low and plant absorbs water from well-watered soil under the influence of root pressure.

Detailed explanation-3: -Guttation is the process of secretion of water droplets from the pores of some vascular plants like grass. Guttation is often confused with dew droplets that condense from the atmosphere onto the plant’s surface.

Detailed explanation-4: -Water is lost as water vapour during transpiration and in guttation, it is lost as liquid droplets. When the transpiration happens, stomata are open but when guttation occurs, stomata are closed as guttation occurs at night time.

Detailed explanation-5: -Evapotranspiration also includes transpiration, which is the water movement from the soil to the atmosphere via plants. Transpiration occurs when plants take up liquid water from the soil and release water vapor into the air from their leaves.
