A) Meristematic cells near the root tip have

1. large nucleus
2. rich protoplasm
3. vacuoles are less in number
4. cell wall is thin and made up of cellulose
5. No intercellular spaces
6. This is an area of cell division

B) The zone of elongation is where the newly-formed cells increase in length, thereby lengthening the root. Beginning at the first root hair is the zone of cell maturation where the root cells differentiate into specialized cell types. All three zones are in approximately the first centimeter of the root tip.
