What is a stem cell |
A stem cell is an undifferentiated cell of an organism which is capable of giving rise to many more cells of the same type, and from which certain other cells can arise from differentiation |
|
|
What’s the function of stem cells in human embryos |
Stem cells from human embryos can be cloned and made to differentiate into most different types of human cells. |
|
|
What’s the function of stem cells in adult bone marrow |
Stem cells from adult bone marrow can form many types of cells including blood cells |
|
|
What’s the function of stem cells in meristems in plants? |
Meristem tissue in plants can differentiate into any type of plant cell, throughout the life of the plant. |
|
|
How can stem cells help prevent diabetes? |
Embryonic stem cells can be used to replace fatty cells in sick people, making insulin producing cells for people with diabetes |

|
|
How can stem cells help plants? |
The meristems can differentiate into any type of plant cell, meaning they can produce clones of whole plants quickly and cheaply, they can be used to grow plants of rare species, also grow crops of identical plants that have desired features e.g disease resistance |
