Describe the process of reproduction in Hydra with the help of labelled diagrams. What is the name of this process of reproduction?
उत्तर
Hydra reproduces by the method of budding. A small outgrowth called bud is formed on one side of its body by repetitive mitotic division. This bud gradually grows into a full hydra, developing its mouth and tentacles. The new Hydra detaches itself from its parent and start living as a separate organism.
