Question 1

Multiple choiceEasy1 mark

During budding in yeast, a small bud receives much less cytoplasm than the larger cell. Which distribution of mitochondria is expected when the cells separate?

Show answer and explanation

Answer: D. Cytokinesis can divide cytoplasm unequally, but each daughter cell must receive at least one mitochondrion. The larger cell may receive more mitochondria, but neither cell can receive none. A: assigns all mitochondria to the larger cell, leaving the bud without one. B: reverses that allocation, leaving the larger cell without one. C: assumes mitochondria can be made anew rather than inherited from pre-existing mitochondria. Remember: Unequal cytokinesis does not mean either daughter can lack mitochondria.
