A
the process that changes less specialised cells into more specialised ones
3
Q
what are meristems?
A
a group of cells near the end of each shoot and root that allows plants to continue growing throughout their lives
4
Q
what happens to the cells in meristems to allow the plant to grow?
A
the cells divide rapidly via mitosis - these cells produce elongation and differenciate into specialised cells that have different functions
5
