Perilymph is neither located in the cochlear duct nor the bony labyrinth of the semicircular duct; it is found in the scala tympani.
The perilymph is an extracellular fluid located in the scala tympani of the inner ear.
The cochlear duct also known as the scala media is filled with an endolymph, not a perilymph, and is located between the tympanic duct and the vestibular duct.
Plants absorb water in a large amount because water is the only medium which is present in a plant for the transportation of minerals. So, the plant absorbs a lot of water even if it is lose by transpiration.
