the growth of hydrilla enables it to compete effectively for sunlight. It can elongate very rapidly, upto an inch a day..until it nears the water surface, where it gets sunlight.

i) It is a submerged hydrophyte found attached to the substratum by adventitious roots in fresh water ponds.

ii) The stem is soft and slender and bears thin and membranous leaves in whorls of 3-8.It limps when taken out of water showing the absence of any mechanical tissue.

iii) The leaves are arranged in such a way to provide least resistance to the flow of water. They lack cuticle and stomata.

iv) The whole plant is covered over by mucilage. It prevents epiphytic growth and protects the plant against the rotting effect of water.
