Explain why cells don't just continue to grow larger as organisms grow larger. Why do cells divide? (Write in complete sentences)

Answer 1

1. The series of events that cells go through as they grow and divide include: G1 phase (growth and metabolic activity), S phase (DNA replication), G2 phase (preparation for division), prophase (condensation of chromosomes), metaphase (alignment of chromosomes at the center of the cell), anaphase (separation of chromosomes), telophase (formation of two new nuclei) and cytokinesis (division of the cytoplasm to form two separate cells).
2. The longest stage of the cell cycle is called the G1 phase.
3. The G1, S, and G2 phases happen during interphase.
4. Mitosis and cytokinesis occur during the M (mitosis)
phase of the cell cycle.
5. Cell division occurs during the M phase of the cell cycle.
6. DNA replication occurs during the S (synthesis) phase of the cell cycle.
7. The cell grows during the G1 phase of the cell cycle.
8. The cell prepares for mitosis during the G2 phase of the cell cycle.
9. There are five stages in mitosis: prophase, metaphase, anaphase, telophase, and cytokinesis.
10. The order of the stages of mitosis is: prophase, metaphase, anaphase, and telophase.
11. The order of the stages of the cell cycle is: G1, S, G2, and M.
12. The order is: G1, S, G2, mitosis, and cytokinesis.
13. The order of actions is: cell grows, DNA replication, cell prepares for mitosis, cell division.
Cells don't just continue to grow larger as organisms grow larger because larger cells are less efficient at carrying out cellular processes and maintaining structural integrity.
Additionally, if cells continued to grow larger, they would eventually become too large to divide, leading to an inability to form new cells and supporting the growth of the organism. To overcome these limitations, cells divide in a process called cell division to ensure efficient cellular processes and proper growth of the organism.
