Question

After observing the prepared slides of binary fission in Amoeba and budding in yeast following observations were reported:

The correct observation is/are:

• A. a and c
• B. b only
• C. c and d
  
• D. d, a and c

Answer 1

The correct option is A

a and c

The correct option is A.

Explanation of the correct option:

1. Binary fission divides a parent cell into two daughter cells, for example, in Amoeba.
2. During binary fission in Amoeba, the parent nucleus appears elongated while dividing into two.
3. Budding is the generation of bud on the surface of a body of an organism which later on can be treated as an independent organism. For example, in yeast.
4. Both yeast and Amoeba are unicellular organisms.

Explanation of the incorrect options:

Option B:

1. Yeast reproduces through budding, which leads to bud formation on a parent yeast cell.
2. Initially, the buds remain attached to the main yeast cell without cytokinesis.

Option C:

1. Amoeba multiplies by binary fission.
2. The chain of buds is observed in budding, which is seen in yeast.

Option D:

The chain of buds is not observed in Amoeba and is seen in yeast.

The correct observations are a and c.
