Biology - Cell Division Flashcards
1
Q
IN ORDER
What are the three stages of cell division?
A
- Interphase
- Mitosis
- Cytokinesis
2
Q
Interphase
A
Before a cell can divide it needs to grow and increase the number of sub-cellular structure such as ribosomes and mitochondira. The DNA needs to replicate and create two copies of each chromosome.
3
Q
Mitosis
A
One set of each chromosome is pulled to opposite ends of the cell and the nucleus divides
4
Q
Cytokinesis
A
The cytoplasm and cell membrane split creating two identical cells
5
Q
What plant tissue can differentiate into any plant cell at any time in the plants life?
A
Meristem tissue
6
Q
Three uses of meristems in plants
A
- Produce clones of plants quickly and economically
- Rare species can be clones to protect them from extinction
- Crop plants with special features such as disease resitant can be cloned to produce large numbers of identical plants for farmers
