Mitosis and Meiosis Flashcards
0
Q
What is Mitosis?
A
-Division of the Nucleus
1
Q
What is the purpose of Cell Division?
A
- Growth
- Repair
- Asexual Reproduction
2
Q
What is Cytokinesis?
A
-Division of the Cytoplasm
3
Q
What happens during Interphase?
A
- Non-dividing stage
- “Resting stage”
- Gap 1 (G1), Gap 2 (G2), Synthesis (S) phase
4
Q
What happens during Prophase Stage?
A
- Nuclear membrane and nuclelolus disappears
- Spindle fibers are formed
- Chromatins condense to thick chromosomes
5
Q
What happens during Metaphase?
A
-Chromatids line up at the equatorial plate
6
Q
What happens during Anaphase?
A
-Chromatids move to opposite poles
7
Q
What happens during Telophase?
A
- Spindle fibers disappear
- Known as Reverse Prophase
- Nuclear membrane and Nuclelolus reform
- Cleavage formation
8
Q
What is Meiosis?
A
- Type of cell division necessary for sexual reproduction
- Number of chromosomes in the cell undergoing meiosis is reduced to half the original number
- Produces Gametes
- Has two stages: Meiosis 1 and Meiosis 2
9
Q
What happens during Interphase I?
A
-Same process in Mitosis
10
Q
What happens during Prophase I?
A
-Crossing over occurs
11
Q
What happens during Metaphase I?
A
-Tetrads align on the equatorial plate
12
Q
What happens during Anaphase I?
A
-Chromosomes are seperating
13
Q
What happens during Telophase I?
A
-Formation of cleavage furrow
14
Q
What happens during Meiosis 2?
A
- Same process as Mitosis
- 4 daughter cells are formed
