Cell types. Cutaway artwork with a scale bar (upper right,in micrometres) showing the relative sizes of eukaryotic cells (those containing a nucleus) and prokaryotic cells (those lacking a nucleus). The eukaryotic cells are larger,and are a plant cell (left) and an animal cell (lower right). The main difference is the presence of a cell wall (brown) and chloroplasts (green) in the plant cell. The cell nucleus is red. The two smaller prokaryotic cells (both at upper right) are bacteria and are gram-negative (left) and gram-positive (right),with the latter having extra cell membranes. The gram-negative bacterium and the animal cell have flagella | |
