3.10 - Cell Cycle Flashcards
The phases of the cell cycle The processes that take place during interphase (8 cards)
1
Q
Why do organisms need new cells?
A
To grow and repair tissues
2
Q
What is the cell cycle?
A
Sequence of steps for cell division
3
Q
What are the three main phases of the cell cycle?
A
- Interphase - This occupies the majority of the cycle as cells prepare for division.
- Mitosis - This is when the nucleus of the cell divides in two.
- Cytokinesis - This is when the whole cell and cytoplasm divides in two to produce two identical cells.
4
Q
What happens during interphase?
A
Cells prepare for division
Preparation involves the following processes:
* Cell growth - This includes an increase in cytoplasm.
* Synthesis of proteins - These proteins are used to replicate organelles.
* Replicating DNA - This results in double the genetic material.
5
Q
What happens during mitosis?
A
Nucleus divides in two
6
Q
What happens during cytokinesis?
A
Cell and cytoplasm divide in two
7
Q
What processes occur during interphase?
3 processes
A
- Cell growth
- protein synthesis
- DNA replication
8
Q
What does replicating DNA result in?
A
Double the genetic material
