Animal cell 2.0 - annotated in English

Description

Based on [Animal cell - Downloadable by Lauri Purhonen on Sketchfab. ](https://sketchfab.com/3d-models/animal-cell-downloadable-ddc40bb0900544959f02d3ff83c32615) Thank you, Lauri! For this model, I updated the nucleolus, added ribosomes and created a smooth endoplasmic reticulum. I also wrote new annotations in English based on information from Encyclopedia Britannica.
