Q.

Parthenogenesis occurs in which of the following animals?

1. Sheep

2. Sponges

Q.

There is no natural death in single celled organisms like Amoeba and bacteria because

1. they cannot reproduce sexually

2. they reproduce by binary fission

3. parental body is distributed among the offspring

4. they are microscopic

Q. In binary fission, ____________________________ .

1. the axis of division is always transverse
2. division of cytoplasm occurs before division of nucleus
3. two daughter cells are formed
4. a small protrusion occurs from the parent cell.

Q. In this method, Parents cell divides into many daughter cells.

1. Fission
2. Binary fission
3. Multiple fission
4. Budding

Q. Differentiate between fission and budding methods of asexual reproduction.

Q. Explain the process of binary fission in amoeba.
