Question

What observation can be made by viewing the slides under the microscope on binary fission in Amoeba and budding in Yeast ?
A)The daughter cells of Amoeba and the bud of yeast are smaller than their respective parent cells.
B)The daughter cells of Amoeba and the bud of yeast are of the same size as their respective parent cells.
C)The daughter cells of Amoeba are bigger than the parent cells but the bud of yeast is smaller than the parents.
D)The daughter cells of Amoeba are smaller than the parents but the bud of yeast is larger than the parents.

Answer 1

Amoeba is a unicellular organism that can change its shape with the help of pseudopods. They reproduce by a type of asexual method, known as Binary Fission. Yeast is unicellular, eukaryotic microorganisms that are classified under Kingdom Fungi. They reproduce asexually by the process called Budding.

Complete answer:
Option A- The daughter cells of Amoeba and the bud of yeast are smaller than their respective parent cells.
In both the organisms, after the replication of genetic material, parent cells divide into two daughter cells by mitosis. Mitosis causes the production of equal sizes of daughter cells which are smaller in size as compared to the parent cells.

Option B- The daughter cells of Amoeba and the bud of yeast are of the same size as their respective parent cells.
Parent cells contain genetic material that replicates and passes in the daughter cells in an equal amount which is not of similar size.

Option C- The daughter cells of Amoeba are bigger than the parent cells but the bud of yeast is smaller than the parents.
Daughter cells of Amoeba are not bigger than the parent cells and the buds of yeast are smaller than the parents.

Option D- The daughter cells of Amoeba are smaller than the parents but the bud of yeast is larger than the parents.
Both Amoeba and Yeast reproduce by asexual methods. Daughter cells of Amoeba are smaller and buds of yeast are also smaller in size.

Hence the correct answer is OPTION(A)

Note: In binary fission, an organism divides to form new individuals that are identical. It is the common process of reproduction in prokaryotic organisms. Steps involved in Binary fission are- Replication of DNA, Growth of a cell, Segregation of DNA, Splitting of cells. Budding takes place in both unicellular and multicellular organisms. The daughter cells in budding are known as Buds.
