Hydrilla is a submerged aquatic plant that exhibits several hydrophytic adaptations to its watery environment:1. "Thin and flexible leaves:" Hydrilla has thin, ribbon-like leaves that are well-adapted to life underwater. a man who lives alone at his home in a certain district had three plants that he treasured so much;an arrow plant that he grew in nutrient rich bottle , a pond weed hydrilla grown in a sealed transparent container that he regularly opened and added sodium hydrogen carbonate to. Explain hydrilla experiment - 11849971Hydrilla Experiment. Hydrilla experiment is done to prove that oxygen is necessary for photosynthesis. Hydrilla is a small plant and hence it is easy to handle them also they are also aquatic plant so it is able to breathe in water whereas land plants are not. With hydrilla , it is easy to set up the experiment. Hydrillas do not have any stomata since they are aquatic there and there is no exchange of oxygen and carbon dioxide like land-based plants. The ... In an experiment on O2 evolution by photosynthesising Hydrilla plant, a pinch of sodium bicarbonate is added to water. The rate of photosynthesis or O2 evolution will Stop Decrease Increase Not be affected
