Cell Wall

Cell wall

Cell wall provides most significant difference between plant cells and animal cells:
Only in animal cells

Layer that surrounds some types of cells and is located outside the cell membrane
Composed of Cellulose (specialized sugars)
Cellulose fibrils are deposited in alternating layers for strength
Pores in cell wall make it permeable, so let water, nutrients, waste, ions pass through -> called plasmodesmata
Rigid structure
