Answer
(a) Budding is a form of asexual reproduction in which a small outgrowth, called a bud, grows from the parent body and develops into a new individual.
(b) Budding is an asexual mode of reproduction.
(c) Budding is seen in Yeast and Hydra. Yeast is a fungus, Hydra is an animal.
(d) The labelled diagram below shows the process of budding in Hydra:
(e) The specific locomotory structures of Hydra, which reproduces by budding, are its tentacles.

One evening, Abdul spotted a lizard in his room. In an attempt to shoo it away with a broom, the lizard's tail suddenly broke off and kept wriggling on the floor. Abdul got sad, thinking he had hurt the lizard badly. His father explained that many lizards can regrow their tails if they lose them. This ability is called regeneration.
Abdul wondered if this meant a new lizard can grow from the broken tail in the same way some animals reproduce new individuals. However, his biology teacher clarified that regrowing a tail is not reproduction. It only replaces a lost body part. In some simple animals, regeneration can actually produce a whole new organism. But in lizards, regeneration only replaces the lost body part (or tail) and does not create a new lizard.(a) Name two animals that use regeneration for producing a new organism.
(b) What type of reproduction do the animals named by you above show?
(c) How is this type of reproduction different from how a dog gives birth to puppies?
