Question

Budding is a normal mode of asexual reproduction in
A)Starfish and Hydra
B)Hydra and sponges
C)Tapeworm and Hydra
D)Sponge and starfish

Answer 1

Budding is an asexual method of creating new species. A new organism is being formed in this process from a small part of the parent's body. A bud shaped is detached to grow into a new organism.

Complete answer:
Both Hydra and sponges reproduce by releasing buds asexually leading to a budding process that gives rise to young animal forms. The bud shape is attached to the body of the animal initially from where it derives its nourishment and then breaks down to become an entity. Organisms such as hydra use regenerative cells for reproduction in budding cycles. In hydra, the bud grows as an outgrowth due to repeated division of cells at a particular location. These buds grow into tiny individuals and when fully grown, separate themselves from the parent body and become new, independent individuals. Gemmula are internal buds found in sponges and are involved in the reproduction of asexuals. It is an asexually replicated mass of cells capable of evolving into a new organism, i.e. an adult sponge.

Asexual reproduction by budding is the most common method of vegetative growth in yeast where small buds (also known as blebs or daughter cells) are produced in the parent cell. The nucleus of the parent cell splits into the nucleus of the daughter and travels to the cell of the
daughter.

Hence, the correct answer is option (B)

Note: Budding is most widely used to multiply a variety that cannot be generated from seed. It is a popular method of producing fruit trees, roses and many varieties of ornamental trees and shrubs. It can also be used for planting trees that cannot be easily grafted with cleft or whip grafts.
