This popular plant is complex and differentiated.
The leaves are thick and have a distinct upper
(chlorophyll cell) layer and a more complex dark
lower layer. You can see the active cell organelles
moving about inside the cell walls.
It bears thousands of hair-like projections which
look like fine jewels under the microscope.
