|
Cell Membrane/Volume Ratio |
Lots of small cells=good, more s/v ratio
One large cells=Bad, less s/v ratio |
|
|
Cell size |
Cells are the same size for different animals, for example a mouse has the same size skin cells as an elephant, an elephant just has more |
|
|
Controling cell division |
The nucleus controls cell division |
|
|
Mitosis |
Mitosis is the division of the nucleus |
|
|
Cytokenesis |
Division of the cytoplasm |
|
|
Equal/Unequal splitting |
Mitosis always equal, Cytokenesis can be unequal |
|
|
Types of reproduction |
Sexual and asexual:
Sexual: Two parents, varied offspring
Asexual: One parent, identical offspring |
|
|
How can growth rate be increase? |
Growth Hormones, came from cadavers (Dead people), now comes from modified DNA |
|
|
Stages of Mitosis |
(Interphase), Prophase, Metaphase, Anaphase, Telophase |
|
|
What happens in Mitosis stages |
Interphase: resting stage, Prophase: Chromosomes appear, Metaphase: Chromosomes line up in center of cell, Anaphase: Chromosomes split and chromatins go to either end of the cell, Telophase: Cell splits |
|
|
Cells that can't undergo mitosis |
Muscle and nerve |
|
|
Cells that can undergo cytokenesis but not mitosis |
Muscle |
|
|
Label a chromosome |
Sister Chromatids: Two strands of chromatin while connected, Chromatin: One strand of chromosome, Centromere: Where chromatin are joined |
|
|
Diffrences between animal mitosis and plant mitosis |
Plant divides with a division plate, animal creates an inclusion |
|
|
What is a cancer? |
Abnormal growth of cells |
|
|
How cancer differs from regular cell |
More active, large nucleus, less specialized |
|
|
What is a carcinogen? |
Cancer causing agent, IE: Radiation, dye, ect |
|
|
What is a oncogene? |
Cancer less gene |
|
|
Types of cancer |
Carcocrome: Cancer in ephilia tissue Melianomia: Cancer in melonimia Lukemia Blood cancer (White cells) Two types, Acute (Fast) chronic (Slow) Sarcoma: Cancer in sarcoma tissue
|
|
|
How cancer is detected |
Biopsy, Xray, Cat scan, MRI scan |
|
|
How cancer is treated |
Chemo therapy, Radiation therapy, and surgery |
|
|
What is Angiogenesis |
New blood vessel growth |
