What are adult stem cells? |
They are stem cells found in tissue and bones marrow of children and adults. They can only specialise into the type of cell of the tissue they're found in |
|
|
|
What is meiosis? |
It is the division of gametes |
Sex cells |
|
|
Where and when are somatic stem cells found? |
They are found in a blastcyst of a developing zygote. (Around 5 - 8 days old). |

|
What is cell differentiation? |
•When a cell becomes specialised to carry out a SPECIFIC function. •Specialised cells can only express the genes characteristics of that cell type through GENE EXPRESSION. • example: muscle cell switches on the genes to carry out it's functions and other genes that the cell does not need is switched off. |
|
|

|
|
What is it meant by multipotent? |

Adult stem cells |
|
|
What are germline cells? |
•It is the cell that produces gametes. • they can divide by mitosis to produce more germline cells or by meiosis to produce gametes |
|
|
|
What will happen if a mutation happens in a germline cell? |
The mutation will end up int the gametes and show up in future offspring |
|
|
|
