A yeast cell in which budding occurs was seen to have:
A yeast cell in which budding occurs was seen to have:
Options
A yeast cell in which budding occurs was seen to have a chain of bud cells.
Marking Scheme
- 11 mark
Hint
Think about what happens when yeast reproduces rapidly in a warm sugar solution before the buds have time to separate.
Quick Oral Answer
Under a microscope, actively reproducing yeast cells show a chain of buds because new buds begin to grow on top of existing ones before they have detached from the parent cell.
Analysis & Explanation
During active budding in yeast (especially in a nutrient-rich sugar solution as described in Activity 7.1), the cell division is rapid. The newly formed buds do not immediately detach from the parent cell. Instead, they remain attached and start producing their own buds, resulting in a characteristic chain of bud cells. Therefore, option 4 is the correct observation.
Common Mistakes
- 1Choosing 'one bud cell' because they assume only one bud forms at a time, neglecting the rapid division that forms chains under active growth conditions.
Interesting Facts
Yeast is a unicellular fungus. Under favorable conditions, a single yeast cell can produce a chain of several buds within just a couple of hours!
