| Cell Division is when a cell divides due to reproduction, growth, or repair. |
|
|
Term
| What is the cycle of Cell Division? |
|
Definition
Interphase
Mitosis: Prophase, Metaphase, Anaphase, Telephase
Cytokinesis |
|
|
Term
|
Definition
| Phase of a cell cycle where it preforms normal functions and copies genetic material in preparation for the cell division. |
|
|
Term
|
Definition
A phase where DNA in the nucleus divides.
4 stages (PMAT) |
|
|
Term
| What happens during Prophase? |
|
Definition
1. Chromosomes become visible
2. nuclear membrane dissolves |
|
|
Term
| What happens during Metaphase? |
|
Definition
| 1. chromosomes line in the middle of the cell |
|
|
Term
| What happens during Anaphase? |
|
Definition
1. Chromosomes separate
2. Chromosomes move toward ends of cell |
|
|
Term
| What happens during Telophase? |
|
Definition
1. Chromatids unwind
2. Nuclear membrane reforms around the chromosomes at each side |
|
|
Term
|
Definition
| the phase where cytoplasm DIVIDES to form 2 identical cells (daughter cells) |
|
|
Term
| Name the Checkpoints in the Cell Cycle |
|
Definition
1. Specialized proteins monitor cell activities and surroundings
2. Proteins send messages to nucleus
3. Nucleus instructs the cell whether to divide or not based from signals from surrounding cell saying "DON'T DIVIDE", the amount of nutrients, the DNA replication, or DNA damage.
(Little time repairs cell. Too much destroys) |

Term
| What does the Golgi Bodies do? |
|
Definition
It removes waste and secretes mucus
(The Garbage Men of the Cell) |
|
|
Term
|
Definition
| It surrounds the cell. It's made up of a lot of water and some protein. |
|
|
Term
| What does a Cell membrane do? |
|
Definition
It supports and protects the cell
(Body Guard of the Cell) |
|
|
Term
| What does the Nucleus do? |
|
Definition
It contains DNA (deoxyribonuleic acid) which carries coded instructions for all cell activity.
(Government/Brain to the Cell) |
|
|
Term
| What does the Mitochondria do? |
|
Definition
It gives energy to the cell
(The Power Plants of the Cell) |

Term
What does a Cell Wall do?
Which type of Cell is it located in? |
|
Definition
the Cell Wall provides support. It is found outside the membrane and is rigid&pourous.
Located in Plant Cells Only |
|
|
Term
| What does the Vacuole do? |
|
Definition
| It turgurs pressure to keep the cell plump and firm. |

|
Definition
It contains chlorophyll which use photosynthesis to make energy for the plant.
It's located in the Plant Cell |

|
Term
| What are the types of Cancer? |
|
Definition
Benign: which does not harm (only crowds)
Malignant: harms (interferes with functions) |
|
|
Term
| What are the causes of Cancer? |
|
Definition
Hereditary (From family)
Environmental carcinogens e.g. tobacco smoke, radiations, UV rays, viruses, HPV & Hepatitis B. |

|
Definition
X-rays, Ultra sounds, CT scanning, MRI
Can also test yourself by ABCD (Asymmetry, Color, Border, Diameter) moles. |
|
|
Term
| What are Treatments for Cancer? |
|
Definition
Surgery: Physically removing cancerous tissue.
Chemotherapy: Stops or slows cancer cells from dividing and spreading with drugs taken orally or injected.
Radiation: Damages cancer cells by using a focused beam or implanting a radio active source into tumor.
Biophotonics: uses light energy to diagnose, monitor, and treat living cells & organisms.
