2018年8月20日 · Cell theory states that all living things are composed of cells, cells are the basic unit of structure and function, and new cells are produced from existing cells. Cells can be classified as prokaryotic, which lack organelles and a nucleus, or eukaryotic, which contain organelles and a nucleus.

Cell Biology powerpoint Presentations free to download. Ideal for teachers or students. An excellent overview of cell biology topics.

Cells differ widely in terms of shape. Misconception: All animal and/or plant cells are identical in terms of structure. For example, all cells contain a nucleus. Red blood cells are enucleated. Misconception: Cells contain only the genetic material that they use. For instance, a skin cell has DNA only for the functioning of that skin cell.
