A forestry laboratory uses shoot-tip meristem tissue from a fully grown oak tree to produce cloned saplings.
Why can the laboratory use meristem tissue from a fully grown tree rather than needing tissue from a young seedling?
Meristem cells can still divide and differentiate throughout the tree's life
Meristem cells stop dividing as the tree grows but restart when removed
Cells in every tissue remain able to divide throughout the tree's life
Meristem cells form when specialised cells divide at the end of the tree's growth
