Vocabulary
The regular sequence of events in which the cell grows, prepares for division and divides to form two daughter cells.
What is the cell cycle?
These are the four stages of mitosis.
What is Prophase, Metaphase, Anaphase and Telophase.
Why do our cells go through the cell cycle?
To grow, reproduce, repair and replace.
This structure breaks down sugars to provide energy for cell activities.
What is Mitochondria?
During this, the cell makes copies of its DNA in its nucleus before cell division.
What is replication?
During this phase, the chromosomes line up along the center of the cell. The chromatids that will go into each daughter cell are lined up on that side of the cell.
What is metaphase?
These are the cells that form at the end of the cell cycle.
What are daughter cells?
This structure is found in animal cells, but not in plant cells.
What is a lysosome?
During this stage, the cell grows, makes a copy of its DNA and prepares to divide.
What is interphase?
During this phase, the chromatids are pulled to opposite ends of the cell. The nuclear membrane reforms around the DNA to create two new nuclei.
What is telophase?
As soon as you break a bone, your body does this.
What is sets the cell cycle in motion to repair the break?
This structure is found in plant cells, but not animal cells.
What is a chloroplast?
This is the final stage of the cell cycle. The cytoplasm divides, distributing the organelles into each of the two new daughter cells.
What is cytokinesis?
During this, DNA condenses into two separate chromosomes, and the nuclear membrane starts to break apart.
What is prophase?
What would happen if a step of the cell cycle was missed?
The cells would not divide into two identical daughter cells. This might result in a mutation of the cell, or the cell might not be healthy.
These are the basic principals of the cell theory.
What is:
1. All living things are made of cells.
2. Cells are the basic units of structure and function in living things.
3. Living cells only come from other living cells.
During this stage, the cell's nucleus divides into two new nuclei and one set of DNA is distributed into each daughter cell.
What is mitosis?
During this phase, the spindle fibers begin to pull the chromatids apart to each side of the cell.
What is anaphase?
How does the number of cells increase with each new division of the cells?
What is the number of cells doubles each time? (One to two, two to four, four to eight, eight to sixteen, etc.)
You broke your bone. What needs to be repaired? (You must name at least TWO things that need repair).
What are bone, skin, muscle and tissue?
