Marking Scheme
- 1Identification of the process as budding in yeast (1 mark)
Hint
Think about which unicellular organism produces a smaller 'outgrowth' that stays attached for a while.
Quick Oral Answer
Yeast reproduces by budding, where a small outgrowth or 'bud' forms on the parent cell body.
Analysis & Explanation
According to the NCERT text, yeast (a unicellular fungus) reproduces by putting out small buds. These buds are initially smaller than the parent cell and remain attached to the tip of the parent cell before they eventually separate and grow further. This matches the description of a smaller cell attached to the tip of a larger cell. Amoeba, on the other hand, undergoes binary fission where the cell splits into two roughly equal halves, not by budding.
Common Mistakes
- 1Choosing Amoeba, which divides by fission into equal halves.
- 2Confusing a bud with a daughter cell of equal size.
Interesting Facts
Yeast buds can sometimes stay attached and form a chain of cells, appearing like a small colony under the microscope.
