Smallest structure in the eukaryotic cell
WebbFigure 4.8 These figures show the major organelles and other cell components of (a) a typical animal cell and (b) a typical eukaryotic plant cell. The plant cell has a cell wall, chloroplasts, plastids, and a central vacuole—structures not found in animal cells. Plant cells do not have lysosomes or centrosomes. WebbGuinness World Records recognizes Nanoarchaeum equitans as the smallest living organism. Eukaryotes (Eukaryota) [ edit] Prasinophyte algae of the genus Ostreococcus are the smallest free-living eukaryote. The single cell of an Ostreococcus measures 800 nm (0.00080 mm) across.
