Question

In hydra the type of reproduction is
A.Binary fission
B.Budding
C.Multiple fission
D.None of these

Answer 1

Hint: This belongs to the invertebrate genus of freshwater animals of the class Hydrozoa. This organism's body consists of a thin or translucent tube that measures up to 30 millimeters long and it can contract. The Hydra body wall comprises two layers of cells which are separated by a thin structureless connective tissue layer called the mesoglea and the enteron, containing intestinal organs.

Complete answer:Binary fission- is asexual reproduction which is the separation of the body into new two bodies. During the process of binary fission, the organism duplicates its genetic material and then divides into two new parts through cytokinesis with each new cell receiving one copy of DNA.
Budding- This is a type of asexual reproduction in which the new organism develops from a bud or the outgrowth due to the cell division at one particular site. It will be a small bulb-like projection coming out from the yeast cell. Since the newly created cells are produced asexually they are clones.
Multiple fission- This is a type of asexual reproduction in which instead of forming only two daughter cells many cells are produced from the parent cells. In this type of division, the nucleus undergoes multiple times of division. Each nucleus with a small bit of cytoplasm forms a membrane around it and becomes individual cells. All the daughter cells which are obtained from the parents are alike and the same in size.
Hence the correct option is B, Budding.

Note: Hydra reproduces asexually by forming buds on the body. These buds are genetically identical which means they are the clones, which grow on the body and simply break off from the parent body when they attain maturity. Hydra possesses numerous buds in different stages of development.
They also reproduce sexually. Some of the Hydra species have separate sexes; some of them are hermaphrodites which means they produce male and female sex organs in the same Hydra. They release the sperm in the water to fertilize another hydra.
