Describe the body organisation of chrysophytes.

(N/A) $\rightarrow$ In chrysophytes, specifically diatoms, the cell wall forms two thin overlapping shells that fit together like a soap box.
$\rightarrow$ The cell walls are embedded with silica, making them indestructible.
$\rightarrow$ Due to this, diatoms have left behind large amounts of cell wall deposits in their habitat over billions of years, which is known as "diatomaceous earth".
