Q.

Multiple fission produces daughter cells that are of the same size as daughter cells produced by binary fission. True or false?

1. True

2. False

Q.

Which of the following is the main difference between binary fission and budding?

1. Budding only occurs in unfavorable conditions.

2. In budding the daughter cell does not separate from the parent while in fission separation occurs.

3. Unlike binary fission, budding does not produce a new individual but allows the organism to become bigger.

4. In budding, the daughter cell is smaller than the parent while in binary fission two equally sized daughters are produced.

Q. Cell wall synthesis is the final step in the formation of daughter cells in many bacteria.

1. True
2. False

Q.

A protective coat called a cyst develops around the cell undergoing multiple fission. Why do you think this happens?

1. The environment is uncomfortable during multiple fission.

2. The cyst has no use.

3. The cyst helps in growth of the organism.

4. None of the above

Q.

Q.

The ability of a cell to divide into several cells during reproduction in Plasmodium is called?

4. Multiple fission

Q. Bacteria reproduce asexually by a process called

1. Replication
2. Translocation
3. Binary fission
4. Meiosis
