Question

What is true about buds developed on hydra?
A. Oldest bud is towards oral region
B. Oldest bud is towards aboral region
C. Both A and B
D. There is no order

Answer 1

Hint: Hydra is exclusively a freshwater organism having different species.
It is very small, just a half-centimeter long. Budding in hydra involves a small bud that is developed from its parent hydra through the repeated mitotic division of its cells.

Complete answer:Organisms such as hydra use its regenerative cells for reproduction in the process of budding. In hydra, a bud develops as an outgrowth due to repeated cell division at one specific site. These buds develop into tiny individuals and, when it is fully matured, it detaches from the parent body and becomes new independent individuals. In the process of budding, there is an outgrowth from the body of the Hydra. As a result of this there is an increase in the cytoplasm of the cell. There was construction at the end of the bud. The bud continues to grow. When the bud is fully grown into an adult individual it gets detached from the body and forms a new cell. The budding is the asexual mode of reproduction therefore genetically identical new organism grows attached to the body of the parent hydra and separates later on; also these buds grow randomly and anywhere so there is no specific order or direction they follow
Hence, the correct answer is option D.

Note:Hydra, a freshwater diploblastic, with a simple but defined body plan, an organized nervous system, and the presence of stem cells. It exhibits many embryonic features even as an adult, a spectacular ability of regeneration, and a lack of organismal aging.
