Do animal cells fall under the ruling regarding drawing animate beings, and what is the ruling on designing a documentary film about them?

A cell is the smallest unit in the composition of a living organism and contains its characteristics. It is not included in what is forbidden to depict. It is permissible to draw human and animal organs, such as the hand and the foot. If this is permissible for a part of the body, then a cell is even more permissible, as it does not clearly show the image of a human or an animal.
