Final answer:
A fungus cell with 12 chromosomes will have 24 chromosomes after interphase due to DNA replication. After mitosis and cytokinesis, each daughter cell will return to having 12 chromosomes, the same as the original cell.
Step-by-step explanation:
Understanding Mitosis in Fungus Cells: When considering the question of how many chromosomes a fungus cell will have after interphase and in each daughter cell after mitosis, we look at the process of cell division in eukaryotic cells. A fungus cell that originally has 12 chromosomes will double its DNA content during interphase, resulting in 24 chromosomes.
However, after mitosis and cytokinesis, each daughter cell will receive an identical set of chromosomes, thus returning to the original number. Therefore, the correct answer to the question is A. 24 and 12.The cell cycle in eukaryotes, including fungi, consists of interphase - during which a cell grows and duplicates its DNA - and the mitotic phase - during which the cell divides. It's important to note that mitosis preserves the chromosome number of the parent cell in the daughter cells. In contrast, meiosis would reduce the chromosome number by half, which is not the case here as we are discussing mitosis.
