How does excess of water removed by the plants?

Plants lose excess water through stomata, lenticels and cuticle. The two processes involved are transpiration and guttation. When water is lost in the form of vapours through the stomata present on the aerial parts of plants, it is called transpiration. It occurs by pulling of water. It occurs only in daytime. When excess water is lost in the form of liquid droplets from the margins of leaves, through hydathodes, it is called guttation. It occurs by pushing of water towards leaf margins. It occurs only at night. Hydathodes are structurally modified pores present on leaf margin.
