Question
Describe the process of reproduction in Hydra with the help of labelled diagrams. What is the name of this process of reproduction?
Solution
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.
