Asexual Reproduction in Multicellular Organisms > Budding

In multicellular organisms like Hydra, when a bud grows on the parent body through cell division and later becomes a new individual, this is called budding.

Hydra:

1. A small outgrowth or bud appears on the parent Hydra due to repeated multiplication of epidermal interstitial cells.
2. The developing bud contains epidermis and gastrodermis, and its cavity remains continuous with the parent gastrovascular cavity.
3. As the bud grows, it differentiates, developing a mouth and tentacles.
4. When fully developed, the bud separates from the parent body.
5. The detached bud attaches to a surface via its basal disc and lives independently as a Hydra.

A-D. Hydra: stages in budding

• In multicellular organisms like Hydra, a bud grows on the parent body through cell division and later detaches to become a new individual.
• The bud arises from repeated multiplication of epidermal interstitial cells, contains both epidermis and gastrodermis, and its cavity stays continuous with the parent's gastrovascular cavity.
• As it grows, the bud develops a mouth and tentacles, then separates and attaches to a surface by its basal disc to live independently as a new Hydra.
