Question

Select the correct statements for the process of budding in yeast:
I. A bud arises from a particular region on the apparent body.
II. A parent cell divides into two daughter cells, here the parental identity is lost.
III. Before detaching from the parent body a bud may form another bud.
IV. A bud when detaches from the parent body grows into a new individual
(A) I, II, and III
(B) III and IV
(C) III, IV, and I
(D) IV, I and II

Answer 1

Hint: It is an asexual mode of producing new organisms. In this process, a replacement organism is developed from a little part of the parent’s body. The newly developed organism remains attached because it grows further. It is isolated from the parent creature when it gets developed leaving scar tissues. As this is often agamogenesis, the newly developed organism may be a replica of the parent and is genetically identical.

Complete answer:
A bud may emerge from any aspect of the plant and a parent cell isolates into two daughter cells, an area of the parent goes into the recently formed daughter cells.

Additional information: In yeast cells, maturing begins with the conditioning of a little segment of the cell wall. This is then trailed by the improvement of a little bulge on the part. At this stage, the projection (bud) is about 1um wide at its base and is roofed by the cell layer of the parent cell. Simultaneously, the atomic division (of the parent cell) likewise happens with the goal that the hereditary material of the parent is passed to the new bud.
Between the cell wall of the mother and the bud, considers have indicated a ring consisting of chitin to create at the narrowing site (at the internal surface of the divider). As the chitin ring develops, making the septum develop inwards, the plasma membrane invaginates bringing about the arrangement of a primary septum.
So the correct answer is ‘(B) III and IV’.

Note: During budding, replication of the parent DNA occurs through the S-phase characterized by DNA synthesis and therefore the M-phase where DNA is copied.
When the new individual yeast cell has isolated from the mother/parent cell, the parent can begin the budding cycle. In any case, the new cell needs to develop (and arrive at the size of the parent/mother cell) first so as to begin growing.
