Which of the following is true regarding the bud development process in Hydra?
Cell divisions at one site
Formation of spore
Splitting of cytoplasm
Splitting of nucleus
Cell divisions at one site
In Hydra, budding is a form of asexual reproduction where a new organism develops from an outgrowth or bud due to repeated cell division at one specific site. This localized cell proliferation forms a small outgrowth, which gradually grows into a mini-Hydra and eventually detaches from the parent organism.
In Hydra, budding is a form of asexual reproduction where a new organism develops from an outgrowth or bud due to repeated cell division at one specific site. This localized cell proliferation forms a small outgrowth, which gradually grows into a mini-Hydra and eventually detaches from the parent organism.
Think of a small branch sprouting out from a single specific node on a tree trunk. Just like the branch grows from localized cell division at that single spot before becoming an independent branch, a bud grows at one site on the parent Hydra's body.
BUD = Building Up via Division (at ONE site)
Budding in Hydra relies on its remarkable regenerative capacity provided by specialized stem cells called interstitial cells. When favorable conditions exist, localized mitotic cell division occurs rapidly at a specific site on the body wall, forming a protuberance or bud. As these cells continue to divide and differentiate, they form tentacles and a mouth, ultimately creating a fully functional daughter Hydra.
Hydra reproduces asexually via budding under favorable environmental conditions.
The process relies on interstitial cells, which are totipotent stem cells in Hydra.
Cell division occurs localized at one specific site to form a protuberance/bud.
Once fully mature, the daughter Hydra detaches from the parent body to live independently.
Rapid mode of reproduction without needing a mate.
Allows fast population increase when food and conditions are favorable.
Does not introduce genetic variation; offspring are genetically identical clones of the parent.
Common example of asexual reproduction in Cnidaria / Coelenterata asked in competitive exams.
Model organism in biological research for studying stem cell regeneration and tissue morphogenesis.
Option B is incorrect because spore formation is typical of fungi (like Rhizopus) and non-flowering plants (ferns, mosses), not Hydra.
Option C and Option D describe cytokinesis and karyokinesis as seen in binary fission (e.g., Amoeba), which is distinct from budding.
A is correct тАФ Budding in Hydra starts with repeated mitotic cell divisions occurring at one specific site on the body wall to form an outgrowth.
Always contrast Hydra's budding (outgrowth at one site) with Yeast's budding (unicellular outgrowth) and Amoeba's binary fission (splitting into two equal halves) for NEET/SSCGLE questions.
