Chemically straightening hair changes the shape of disulfide bonds, which alpha keratin protein; this is the second protein structure. However, as the hair continues to grow out, this keratin protein grows with it, thus outlasting the effects of the chemicals which change the shape of the protein.
In a one word response, mitosis.
In an explanation: Before the replication process, an ordinary sex cell contains only has 23 chromosomes. That is half the amount of a normal cell.

I've pasted some images down below that might help you a lot. (Left - leaves; Right - coniferous trees).
Hope it helped,
Happy homework/ study/ exam!
