Solution

Animal cells:
Animal cells are eukaryotic.
They possess a true nucleus and various membrane-bound organelles.
Cells are mostly colourless and transparent.
However, red blood cells that are present in higher vertebrates contain a high amount of iron that gives them deep-red colour
The animal cells appear blue when they are stained with dyes such as trypan blue or methylene blue.
