ACTIVITY 4: CELL DIVISION
1. Distinguish between somatic and reproductive cell division and explain the importance of each.
Somatic cell division is a type of cell division wherein the daughter cells that are produced are similar to the parent cell. In this process, there is a division of genetic material and during which the cell nucleus breaks down and forms two fully functional nuclei. On the other hand, reproductive cell division is a type of cell division that reduces the number of chromosomes in the parent cell by half in order to produce four gamete cells. The somatic cell division is important it plays an important role in the production of new cells intended for growth and in the replacement of damaged or worn-out cells. Meanwhile, reproductive cell division is important because it produces gametes that contain a certain number of chromosomes that are needed for sexual reproduction.
2. What is the significance of interphase?
Interphase is the period of the cell cycle wherein the cell is not yet dividing. Its significance in the cell cycle is that it gives time for the cell to make needed preparations before division since in this part, the cell grows, makes essential proteins, and duplicates its chromosomes.
