Answer:
A. A yeast cell reproduces itself
Explanation:
Yeast cell can reproduce asexually either by budding or fission. No matter which process, the ultimate result is cell division.
In fission, first the nucleus divides into two nuclei so that the cell contains two nuclei. Then, a constriction is laid down between the cell which eventually divides the cell into two daughter cells, each with its own nuclei.
In budding, the cell wall at one corner of the yeast softens. This portion starts to grow as a bud while still attached to the mother cell. Eventually the nucleus also divides with one daughter nuclei migrating to the bud. Finally when the bud attains the size of parent cell, cell division occurs.
Answer:
A. A yeast cell reproduces itself.
Explanation:
Should be the right answer because cell division is necessary during reproduction. Like a sponge, it separates itself (essentially the cells) and regrows the parts needed.
