Students observed and compared the structures of plant (onion) and animal (cheek) cells under a microscope. This exercise helped students understand the differences between plant and animal cells.
Observations:
*Onion Cells:*
1. *Cell Wall*: Visible, rigid structure surrounding each cell.
2. *Cell Shape*: Rectangular, brick-like shape.
*Cheek Cells:*
1. *Cell Shape*: Irregular, rounded shape
Comparison:
1. *Cell Wall*: Present in onion cells, absent in cheek cells.
2. *Cell Shape*: Onion cells are rectangular, while cheek cells are irregular.
3. *Vacuoles*: Larger and more prominent in lant cells.
This exercise helped students understand the structural differences between plant and animal cells, highlighting the unique features of each cell type.
