Scientists grow cells from a plant meristem. Some cells continue dividing, while others differentiate into specialised tissues. No mutations occur.
Which statement explains how both processes contribute to producing a complete plant?
Division changes chromosome sets; differentiation increases the number of cells.
Division produces specialised tissues; differentiation changes the chromosome number.
Division increases cell numbers; differentiation produces the required specialised tissues.
Division halves chromosome numbers; differentiation restores the original chromosome sets.
