Question

Explain how amoeba and hydra multiply

Answer 1

amoeba multiply itself by the process of binary fission. amobea doubles
its nucleus and cytoplasm and divided the parent cell into two daughter cells.
hydra multiply itself by the process of budding. In hydra, actively dividing cell divides continuously and forms a outgrowth projection called bud. The bud grows and seperates from parent cell after getting maturity.

Answer 2

Amoeba multiplies by binary fission and Hydra multiplies by budding.

Explanation:

Multiplication of Amoeba:

•Multiplication of Amoeba occurs by binary fission process. It is a kind of asexual reproduction.

•In this process, a cell of Amoeba undergoes division by mitosis process and divides into two.

•The nucleus and also the cytoplasm gets doubled and then the parent Amoeba cell gets divided into equal daughter cells.

Multiplication of Hydra:

•The multiplication of the organism Hydra occurs by budding process. This is also a kind of asexual reproduction.

•In this process, at one particular portion of the body of Hydra, a small outgrowth called bud develops. This remains attached to the parent body and obtains nutrition.

•Once the bud becomes mature, it gets detached from the body of parent and lives as a new Hydra individual.
