Marking scheme

  1. 1.1 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.

Common mistakes

  1. 1.Choosing 'one bud cell' because they assume only one bud forms at a time, neglecting the rapid division that forms chains under active growth conditions.

Analysis and 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.

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!
