Plant growth and development are consequences of three processes: cell division (the process called mitosis), cell enlargement, and cell differentiation. Cell division in the meristem tissues at the tips of roots and shoot tips is primarily responsible for increases in the length of these plant parts. Cell division in the cambium tissues of the roots and stems causes these plant parts to.
Try the Incredible Edible Cell. Have your students study plant cells (an onion cell is a great cell to observe) and animal cells. Then, tell them to build a 3-D cell (not drawn) showing the lysosomes, mitochondra, cell membrane, cell wall (if a plant cell), etc. But the trick is, it has to be totally edible.

Pores in the cell wall allow molecules to pass through. The cell wall has two parts. The primary cell wall is formed during the growth of the cell. After the cell has stopped growing, a secondary cell wall forms.
