Question

use the diagram and your notes to answer the following questions.

1. what is a series of events that cells go through as they grow and divide?
2. what is the longest stage of the cell cycle called?
3. during what stage does the g1, s, and g2 phases happen?
4. during what phase of the cell cycle does mitosis and cytokinesis occur?
5. during what phase of the cell cycle does cell division occur?
6. during what phase of the cell cycle is dna replicated?
7. during what phase of the cell cycle does the cell grow?
8. during what phase of the cell cycle does the cell prepare for mitosis?
9. how many stages are there in mitosis?
10. put the following stages of mitosis in order: anaphase, prophase, metaphase, and telophase.
11. put the following stages of the cell cycle in order: g2, s, g1, m.
12. put the following in order: g2, g1, s, mitosis, cytokinesis.
13. put the following actions in order: dna replication, cell grows, cell division, cell prepares for mitosis.
14. explain why cells don’t just continue to grow larger as organisms grow larger. why do cells divide? (write in complete sentences)

Explanation:

1. The cell cycle is the series of events cells go through as they grow and divide.
2. Interphase is the longest stage of the cell cycle.
3. G1, S, and G2 phases occur during interphase.
4. Mitosis and cytokinesis occur during the M - phase.
5. Cell division occurs during the M - phase.
6. DNA replication occurs during the S - phase.
7. The cell grows during G1 and G2 phases.
8. The cell prepares for mitosis during G2 phase.
9. There are 4 stages in mitosis.
10. The order of mitosis stages is prophase, metaphase, anaphase, telophase.
11. The order of cell - cycle stages is G1, S, G2, M.
12. The order is G1, S, G2, mitosis, cytokinesis.
13. The order is cell grows (G1), DNA replication (S), cell prepares for mitosis (G2), cell division (M - phase).

For the last question, cells don't just continue to grow larger because as a cell grows, its surface - area to volume ratio decreases. This makes it less efficient for the cell to exchange materials (such as nutrients and waste) with its environment. Cell division allows for the maintenance of an optimal surface - area to volume ratio and also for growth, repair, and reproduction of organisms.

Answer:

1. The cell cycle
2. Interphase
3. Interphase
4. M - phase
5. M - phase
6. S - phase
7. G1 and G2 phases
8. G2 phase
9. 4
10. Prophase, metaphase, anaphase, telophase
11. G1, S, G2, M
12. G1, S, G2, mitosis, cytokinesis
13. Cell grows, DNA replication, cell prepares for mitosis, cell division
14. As a cell grows, its surface - area to volume ratio decreases, making it less efficient for material exchange. Cell division helps maintain an optimal ratio and is necessary for growth, repair, and reproduction.
