Cell Division |
When parent cells split and create daughter cells |
|
|
Mitosis |
Form of cellular division where daughter cells are created and both cells have chromosomes and a nucleus |
|
|
Meiosis |
A form of cellular division where four daughter cells are created and each cell has half the set of chromosomes |
|
|
Life Cycle |
The cycle of life - including: birth, youth, reproduction, and death . |
|
|
Life Span |
the length of time for which a person or animal lives or a thing functions |
|
|
Life Expectancy |
How long one lives or functions |
|
|
asexual reproduction |
one parent of an organism can reproduce an offspring by itself- that is also an identical version of its self. ** It only inherits the genes of that one parent. |
|
|
sexual reproduction |
two or more parents reproducing something that has the genes of both parents |
|
|
Sperm |
The male reproductive cell |
|
|
Egg |
Female reproductive Cell |
|
|
zygote |
Combination of the sperm and egg. All genetic information is transfered to the cell at this stage. |
|
|
Inter-phase |
The phase of a cell cycle copies its DNA in preparation for mitosis. This is also the longest phase a cell spends time in. |
|
|
fertilization |
When the female and male reproductive cells meet (sperm and egg) they create a fertilized egg. |
|
|
pro-phase |
The first stage of cell division. |
|
|
Metaphase |
The second stage of cell division where the chromosomes become attached to the spindle fibers. |
|
|
anaphase |
stage of cell division in which the chromosomes move away from one another to opposite poles of the spindle |
|
|
telo-phaes |
a stage of cell division where the chromosomes move to the opposites end of the cell. |
|
|
identical |
Same exact things |
|
|
chromosomes |
threadlike structure of nucleic acids and proteins found in the nucleus of most cells. They carry genetic information. |
|
|
Cancer |
Uncontrollable division of abnormal cells. |
|
|
malignant |
a cancerous tumor cell |
|
|
tumor |
an abnormal mass of tissue |
|
|
benign |
non-cancerous tumor that causes lumps |
|
|
What are the five steps of mitosis |
1: Interphase 2: Prophase 3: Metaphase 4. Anaphase 5.Telophase |
|
|
What is the purpose of mitosis? |
to make two new identical cells with complete sets of chromosomes |
|
|
Purpose of Meiosis |
1: creating 4 new cells with only half a set of chromosomes in each for the purpose of SEXUAL REPRODUCTION |
|
|
Similarities between mitosis and meiosis |
Both are ways cells divide and reproduce Both require the cells to divide Both are required for sexual reproduction |
|
|
Difference between mitosis and meiosis |
Mitosis produces two cells from one parent using one division event. However, meiosis produces four |
