CB2 Stem cells and growth Flashcards
What process do animals use to grow?
Cell division
What 2 processes do plants use to grow?
Cell division, cell elongation
What are the 2 most common measurements for growth in babies?
Mass, length
What does it mean if a baby is in the Nth percentile for mass?
The baby has a larger mass than N% of the population at that age.
What is cell differentiation?

What are the 2 types of stem cells in humans?
Embryonic, adult
How are embryonic stem cells different to adult stem cells?
Embryonic stem cells can differentiate into any specialised cell, adult stem cells can only differentiate into a few specialised cells.
Where are adult stem cells found in humans?
Bone marrow
Where are stem cells found in plants?
Meristem
What are the 3 main uses of stem cells in medicine?
Replacing damaged or faulty cells, growing tissue / organs for transplants, growing cells / tissue for research
What is the meristem?
The meristem is formed of stem cells in plants. It is found in the roots and shoots where the plant is growing.
