Mitosis and Meiosis Flashcards
1
Q
why does mitosis occur
A
it makes new cells in the body for growth and repair
2
Q
What type of cells do mitosis?
A
Diploid cells
3
Q
What are the 5 stages of mitosis
A
- Interphase
- Prophase
- Metaphase
- Anaphase
- Telophase
4
Q
Describe the stages of mitosis
A
- Interphase= this is when DNA is duplicated ready for mitosis
- Prophase= this is when chromosomes condense and also the membrane around the nucleus breaks allowing chromosomes to be free
- Metaphase= chromosomes line up in the middle of the cell
- Anaphase= they are pulled to opposite ends of the cell
- Telophase= membrane forms around the chromosomes
5
Q
What is it called when two identical daughter cells are formed in mitosis
A
Cytokinesis
6
Q
What is the purpose of meiosis
A
This is for sexual reproduction and it produces genetically different cells
7
Q
What type of cells do meiosis
A
Haploid cells
8
Q
How many cells does meiosis produce
A
4 genetically different cells
9
Q
How many cell divisions occur in meiosis
A
2
10
Q
Discribe the process of meiosis
A
- Cell duplicates it’s DNA so there is enough for each new cell
- Chromosomes line up in the middle of the cell and 1 chromosome in from the mother and the other is from father
- Chromosomes are separated to opposite ends
- A new cell will then form contain the mothers and fathers DNA
- Chromosomes line up again for second division and they are pulled apart
6 they also form cell and they form 4 genetically different haploid cells
