Term
| What is sexual reproduction? |
|
Definition
The reproduction that requires the fertilization(fusion) of gametes (sex cells)
Female: Egg
Male: Sperm |
|
|
Term
| What is asexual reproduction? |
|
Definition
| when offspring are genetic copies of the parents and of each other. Are single celled organisms |
|
|
Term
What are the steps phases in Mitosis?
(Remember P.M.A.T) |
|
Definition
Prophase
Metaphase
Anaphase
Telophase |
|
|
Term
|
Definition
| When the chromosomes of the cell become dense. Each duplicated chromosome appears as two identical sister chromatids. |
|
|
Term
|
Definition
| When the chromosomes are aligned at the metaphase plate |
|
|
Term
|
Definition
| When the paired sister chromatids move to opposite ends of the cell |
|
|
Term
|
Definition
| This is the last stage of mitosis where the chromosomes are cordoned off in distinct new nuclei in the emerging daughter cells. Cytokinesis is also occurring at this time |

|
Term
| Prokaryotes reproduce by what? |
|
Definition
|
|
Term
| Explain Binary fission in prokaryotic cells? |
|
Definition
Step 1. Duplication of chromosomes and separation of copies
Step 2. Continued elongation of the cell and movement of copies
Step 3. Division into two daughters |

Term
| Chromosomes are made up of what? |
|
Definition
chromatin a combination of DNA and protein molecules.
*are not visible in cell until cell division occurs* |
|
|
Term
| Sister chromatids are different from daughter chromatids how? |
|
Definition
| Sister chromatids are connected at the centromere and daughter chromatids are two different cells with the genetics |
|
|
Term
| How many cells are in the human body? |
|
Definition
|
|
Term
| What is the cell cycle for eukaryotic cells? |
|
Definition
G1: between cell division and DNA synthesis. The cell increases it's supply of proteins, number of organelles, mitochondria, and ribosomes, and grows in size.
S: DNA synthesis, DNA replication occurs
G2: After DNA synthesis but before all division
(prep for division)
M: the overlapping processes of mitosis and cytokinesis |
|
|
Term
|
Definition
Typically occurs during telophase
Division of the cytoplasm
Different in animal and plant cells |
|
|
Term
| What is Anchor Dependence? |
|
Definition
| when normal cells divide only when they have a solid surface on which to attach and anchor themselves |
|
|
Term
| What happens what animal cells touch each other? |
|
Definition
| They stop dividing, this is called Density dependent Inhibition |
|
|
Term
| When the cell cycle is "out of whack" cells become what? |
|
Definition
|
|
Term
| Name the types of tumors? |
|
Definition
Benign tumors: remain at the original site
Malignant tumors: can spread into neighboring tissues |
|
|
Term
|
Definition
| the spread of cancer cells beyond their original site by traveling through lymph and blood vessels |
|
