Cell Cycle |
Cycle of growth, development, and division that most cells in an organism go through |
|
|
What are the two main phases of cell cycle? |
Interphase and mitotic phase |
|
|
What is the period if growth and development for a cell? |
Interphase |
|
|
What are the three phases of interphase? |
Rapid growth and replication of the organelles Replication of the dna Preparation for cell division |
|
|
What is dna? |
The genetic information in a cell |
|
|
Interphase begins with a period of ________ __________. |
Rapid growth |
|
|
What is the name of interphases first stage? |
G1 |
|
|
What happens in G1 phase? |
Organelles are formed |
|
|
What is the 2nd stage of interphase? |
S stage |
|
|
What happens in the S stage of interphase? |
The cell replicates its strands of chromatin (the dna) |
|
|
What are the two identical strands of dna that make up the duplicated chromosome? |
Sister chromatids |
|
|
What are sister chromatids held together by? |
Structure called the centromere |
|
|
What happens during anaphase? |
Sister chromatids in each duplicated chromosome separate. |
|
|
During anaphase how are the duplicated chromosomes separated? |
Separated and pulled in opposite directions by spindle fibers |
|
|
What happens during telophase? |
Chromosomes begin to uncool and two new identical nuclei form |
|
|
What happens after mitosis? |
Cytokinesis |
|
|
What is cytokinesis? |
Usually divides a cells cytoplasm forming a new cell membrane around each daughter cell |
|
|
In animal cells what happens in the middle of the cell and what does it do? |
A furrow. It gets deeper until the cell membrane comes together to divide the cell. |
|
|
What grows in plant cells what grows? |
Cell plate grows outward toward a new cell Wall until new cells form. |
|
|
What is the final stage of interphase? |
The G2 stage |
|
|
What is the G2 stage? |
It is a period of growth and final preparation for mitosis |
|
|
What does a cell do before it divides? |
It makes copies of all its organelles. |
|
|
What divides in mitosis? |
The nucleus and its contents divide |
|
|
In cytokinesis what divides? |
The cytoplasm and its contents divide |
|
|
What is the result of mitosis and cytokinesis? |
Two new daughter cells are the result |
|
|
What happens during prophase? |
Duplicated DNA condenses into chromosomes |
|
|
What happens during metaphase? |
The chromosomes line up in the middle of the cell |
|
|
What is the results of cell division |
1. The cell cycle results in two new daughter cells that are genetically identical to each other and to the original cell which no longer exists
2. The cell cycle is important for reproduction and some organisms growth and multicellular organisms replacement of worn out or damage cells and repair of damage tissues |
|
|
What happens during mitosis? |
During mitosis the nucleus and its contents divide in two. |
|
|
Who is my favorite out of all the people in my family? |
My Neek. |
