Students were asked to observe the permanent slides showing different stages of budding in yeast under high power of a microscope.
(A) Which adjustment screw (coarse/fine) were you asked to move to focus the slides?
(B) Draw three diagrams in correct sequence showing budding in yeast.
When you study a slide showing different stages of budding in yeast, you observe the following stages:-
I. The bud may get separated from the parent body and develop into a new individual.
II. The body of the bud develops and gives rise to another baby bud.
III. A bud comes out in any direction from the body of the parent cell.
IV. Thus they may form a colony.
The proper sequence of the above stages is
(A) II, I, III, IV
(B) II, III, I, IV
(C) III, II, l, IV
(D) III, I, II, IV
