Mitosis followed by cytokinesis result in two daughter cells Web11 mrt. 2024 · The correct answer will be option- Mitosis takes longer because it involves more chromosomes and is a more complicated process. Explanation: The binary fission is a process which divides a parent cell into daughter cells common in prokaryotes. The mitosis is a type of cell division which also produces two daughter cells from a single parent. dan cases a4-h20WebMeiosis is a type of cell division that decreases the number of chromosomes by half and produces four gamete cells. This cell division starts with a diploid parent cell which means it has two copies of each chromosome.
