ADDITIONAL INFORMATION
· Smallest Human Cells: Erythrocytes 6-8µm in diameter. Blood platelets are 2-3µm in diameter but they are considered to be cell fragments instead of being cell themselves.
· Cell Organelles without Membrane Covering: Ribosomes, Centrosome, Centriole, Nucleolus ( inside nucleus), cytoskeletal structures.
· Cell Organelles with Single Membrane Covering: Endoplasmic reticulum, Golgi apparatus, Vacuole, Lysosome, Sphaerosome, Peroxysome,Glyoxysome, Thylakoid (lamella inside chloroplast).
· Cell organelle with Double Membrane Covering: Plastids (Leucoplast, Chloroplast, Chromoplast), Mitochondria, Nucleus.
· Largest Organelle: Nucleus followed by mitochondrion in animal cell and chloroplast in photosynthetic plant cell.
· Smallest Organelle: Ribosome.
· GERL:Golgi body, Endoplasmic reticulum and Lysosome complex.
· GER:Golgi body, Endoplasmic and Reticulum complex.
