Cell Division Flashcards
Where are the cells chromosomes found?
In the nucleus
Compared to a cell, a gamete has…
Half the genetic information
Mitosis produces daughter cells with…
The same number of chromosomes as the parent cell
How many pairs of chromosomes does a human body cell contain?
23
What is mitosis?
Mitosis is the type of cell division that leads to growth or repair
What happens when a cell divides by mitosis?
Two new cells form, each cell is identical to the other one and the cell they were formed from
What are the stages of mitosis?
- parent cell
2 chromosomes make identical copies of themselves - they line up along the centre
- they move apart
- two daughter cells form with identical chromosomes to the parent cell
What is a gamete?
Sex cells; men= sperm, women= the eggs
What is meiosis?
a type of cell division that results in four daughter cells each with half the number of chromosomes of the parent cell, as in the production of gametes and plant spores
What are the main features of meiosis?
the chromosomes are copied
the cell divides twice, forming four gametes
What are the stages of meiosis?
Chromosomes divide, similar chromosomes pair up, sections of DNA get swapped, pairs of chromosomes divide, chromosomes divide
As a result of meiosis, how many cells are produced?
Two
