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.
