Question

Identify the figures showing the process of budding in yeast.

A- I,II and III
B- II and IV
C- I,II and IV
D- III,IV and I

Answer 1

Asexual reproduction includes the budding process. A tube-like small projection coming out from the cell is known as a bud. The new organism split from the parent organism only when it is matured and behind it the new mature organism leaving the scratch tissue.

Complete answer:
Let us get the correct answer from the given option

According to option A primarily in yeast bud form multiple chain then it forms single chain and after it single cell is formed which is totally wrong.
According to option b only II and IV options are involved. In budding yeast bud form the chain and then divide into two parts which is also wrong.
Option c is also wrong because according to it in budding formation in yeast the 1st step is bud multiple chain formation then bud forms a single chain and then its single cell divides in two parts.
Option d is correct because according to it bud is formed in a single cell. Then the bud develops and divides into two parts and then a chain of buds is formed.

Additional information: There are four major types of asexual reproduction.
1- Binary fission- In this a single parent is divided in two parts and doubles its DNA.It occurs in bacteria.
2- Budding- Bud forms on the surface of the parent body which detach after maturation.Its examples are yeast and hydra.
3- Fragmentation- In this process the new organism developed by fragmentation of the parent body. It occurs in starfish, coral ,sponges etc.
4- Parthenogenesis- In this the embryo develops from an unfertilized egg. Amphibians ,fishes, reptiles are examples.
Note: Budding and fragmentation are not the same . In budding buds is an outgrowth that develops from the parent body while in fragmentation the body of parent breaks in fragments and these fragments form the new individual.
