Question

Write the stages observed while studying the permanent slide of budding in yeast.

Answer 1

Hint: Asexual reproduction is typical in lower plants and in some lower animals. This is a method of accelerated replication in which the new species generated are genetically similar to the parent.

Complete answer:
Reproduction in organisms may be either sexual or asexual. The method of reproduction that happens without the development of gametes is called asexual reproduction. Sexual reproduction is the type of reproduction in which fusion of the male and female gametes takes place.

Yeast is a unicellular organism that belongs to the Fungi kingdom. Most yeasts replicate asexually through the mechanism of asymmetric division called budding. Small buds are formed on the parent body as the nucleus separates. These buds grow into small individuals and when fully grown, detach themselves from the parent body and become new individuals.

Stages seen during budding in yeast are-

i) The parent cell produces small protuberance that develops into a bud.
ii) The nucleus of the parent cell divides and moves into the daughter cell.
iii) The bud is isolated from the body of the mother.
iv) Budding is replicated and a chain of buds is formed.
(v) The daughter cell formed during the budding is usually smaller than the mother cell.

Note: Asexual reproduction may be of different forms, such as binary fission, multiple fission, fragmentation, spore formation, budding, and vegetative propagation.
