The Cell Cycle
Most cells in an organism go through a cycle of growth, development, and division is called what?
the cell cycle
Before the cell cycle starts, DNA is the what fom?
Chromatin
The second stage of the cell cycle is what phase?
The Mitotic phase.
Most cells in an organism go through a cycle of growth, development, and division is called what?
the cell cycle
What is the smallest unit of life?
A cell.
• to grow and develop,
• to replace cells that are old or damaged, and
• to produce new cells
During the G1 stage of Interphase, what happens to the cell?
Rapid growth and replication of organelles within the cell
Within mitosis, what divides within the cell?
the nucleus and the cell contents
What kind of cells reproduce through the cell cycle?
Unicellular Organisms make identical offspring.
True of False
A unicellular organism can only be a prokaryotic organism?
FALSE.
A unicellular organism can be a prokaryotic or eukaryotic.
Which phase is the period of a cell’s growth and development?
Interphase
During the S stage of Interphase, what happens to the cell?
growth and chromosomes form and replicate
Within cytokinesis, what divides within the cell?
How does the cell cycle allow for the cell to grow?
A single multicellular organisms can grow and develop from one cell.
What is the difference between a prokaryotic and eukaryotic cell?
A prokaryotic cell does NOT contain a membrane-bound nucleus.
A eukaryotic cell does have a membrane-bound nucleus.
What are the three main reasons a cell goes through interphase?
• rapid growth and replication, or copying, of the membrane-bound structures called organelles,
• copying of DNA, the genetic information in a cell, and
• preparation for cell division.
During the G2 stage of Interphase, what happens to the cell?
growth and cellular functions; organelle replication
Name the four stages of the mitotic phase?
1. prophase
2. metaphase
3. anaphase
4. telophase
How can the cell cycle replace old or broken cells?
What is the name of a unicellular organism that is made of one eukaryotic cell?
What are the three stages of Interphase?
G1
S
G2
During interphase, what is in place between each stage that helps reduce mistakes?
Checkpoints
Explain how is cytokinesis in a plant cell different?
The cell forms a membrane-bound disk called a cell plate. The cell plate grows outward toward the cell wall until the two new cells form.
Provide an example of how cell division can help repair certain damages to the body?
When someone breaks a bone, there is new bone growth that allows for the bone to heal over time.
List the order of organization starting from a cell to a organism?
Cell, tissue, organ organ system, organism
