In body cells the.... are normally found in pairs. body cells divide by.....
In body cells the chromosomes are normally found in pairs. body cells divide by Mitosis.
2 of 14
What do Chromosomes contain?
The chromosomes contain genetic information.
3 of 14
When cells divide what is copied? What is produced when a cell divides by mitosis?
When a body cell divides by mitosis 1- copies of the genetic information is made 2- Then the cell divides once to form 2 genetically identical body cells
4 of 14
why do cells divide by mitosis?
Mitosis occurs during growth or to produce replacement cells.
5 of 14
How do the chromosomes in the body differ from those of gametes?
body cells have 2 sets of chromosomes; sex cells (gametes) only have one set
6 of 14
Where are gametes made in humans?
Cells in reproductive organs - testes and ovaries in humans- divide to form gametes
7 of 14
What is produced when a cell divides by Meiosis?
When a cell divides to form gametes -copies of the genetic information is made - then the cell divides twice to form 4 gamete, each with a single set of chromosomes.
8 of 14
When gametes join at.... a single body cell with.... pairs of chromosomes is formed. a new individual then develops by this cell repeatedly dividing by......?
When gametes join at fertilisation, a single body cell with new pairs of chromosomes is formed. a new individual then develops by this cell repeatedly dividing by mitosis

What is the difference between differentiation in animal cells and plant cells? What are mature animall cells restricted to and how is this different to mature plant cells?
Most types of animal cells differentiate at an early stage whereas many plant cells retain the ability to differentiate throughout life. in mature animals, cell division is mainly restricted to repair and replacement
10 of 14
What are stem cells? Where can we get stem cells from?
Cells from human embryos and adult bone marrow, called stem cells can be made to differentiate into many different types of cells.
11 of 14
What can human stem cells do?
Human stem cells have the ability to develop into any kind of human cell.
12 of 14
How might we be able to use stem cells?
treatment with stem cells may be able to help conditions such as paralysis.
13 of 14
The cells of the offspring produced by..... reproduction are produced by..... from the parental cells. they contain the same ..... as the parents?
The cells of the offspring produced by asexual reproduction reproduction are produced by mitosis from the parental cells. they contain the same alleles as the parents.
