Growth in Plants and Animals

 

 

Growth in plants:

·  Grow through all their lives

·  Meristems are a place where cells keep dividing

·  Once cells have divided, they get longer (elongate)

·  Meristem can specialise/differentiate

 

Growth in animals:

·  Stop growing when they become adults

·  Have stem cells that can differentiate

·  Most animals cannot regrow damaged limbs

 

All the cells in an embryo are stem cells. This means they can produce any kind of cell. Only a few cells in an adults body are stem cells, and these are used to help repair damaged tissue.
