Answer: Because the cell will expand and burst
When a cell is frozen, that means the cell temperature is going to be lowered extremely. Ice has more volume than water which is why it floating inside water. That's why if you put water in a plastic container then freeze it, the container will get pressured and swollen. If the container is not elastic enough(metal, glass), it will burst.
Same like that, the cell that got frozen can be burst too.

Sudan changes to deep orange or red in the presence of lipids. Sudan in not soluble in water lipids will absorb sudan's particle that will cause the change in color. Lipids will form distinct fat layer in the solution. This can be done during experiment where a macromolecule is unknown. Application of this experiment applies in health such as during confirmation of excessive fat in stool. The affinity of this dye to the lipids is high and alcoholic solutions of sudan dye can also be used.
