Answer:
it means it is multicellular.
Answer:
In meiosis, chromosome number in daughter cells is reduced by half while in mitosis the chromosome number doesn't change.
Explanation:
In mitosis there is a single cell division, while in meiosis there are 2 cell divisions.
In both cases the process start with the replication of DNA, so each chromosome has two sister chromatids.
- In mitosis, the sister chromatids separate, resulting in two daughter cells identical to the original cell, before the DNA replicated.
- In meiosis, homologous chromosomes separate during the first cell division, giving two daughter cells with half the chromosome number of the original cell, but each of them still has two chromatids. During the second cell division the chromatids separate, resulting in a total of four daughter cells, each with half the chromosomes than the original one.
