Typical amimal cell
A typical cell consists of two portions, one, te firmer, forming an excessively delicate meshwork enclosing its cavities the second more fluid part. Therefore, when highly mangnified, the appearance would be essentialluy like a sponge fully saturated with water. The protoplasm the sponge work, and possibly the fluid part is living and both are transparent.
