A look at the cells of different organisms and a comparison of the structures found in plant and animal cells. All animal cells are surrounded by a membrane which contains the cytoplasm.

3 This discovery implies that prokaryotes may have possessed more advanced cellular structures and functions than previously thought, potentially influencing how the first eukaryotic cells emerged.

Do similar mechanisms operate in plant and animal stem cells to maintain long-term division and pluripotency? In conclusion, at least some of the genes that control the stem cell state in animals ...
