Prokaryotic and Eukaryotic
Prokaryotic cells are the characteristic of bacteria and blue green algae. The size ranges mostly from 1-10um. Multicellular forms are rare. Cell wall present in most but not in all cells. Plasma membrane is present. Nucleus is absent. Nucleoid region is present where genetic material resides. Nuclear Membrane is absent. Chromatin with Histone is absent. Each cell has only one chromosome. The chromosome is circular ring lacking a centromere. Nucleoi and Mitotic apparatus is absent. Nucleolus is absent. Plasmids is commonly present. Mesosome performs the function of golgi bodies and mitochondria and also help in the separation of chromosomes during cell division. Mitochondria, Endoplasmic Reticulum, Vacuoles, Lysosomes, Chloroplase centrioles are absent.
Eukaryotic cells are found in all animals and plants, except blue green algae and bacteria. The size ranges mostly from 10-100um. Multicellular forms are common, with extensive tissue formation.Animal cell lacks cell wall but plant cell is made up of cellulose and chitinous cell wall is present in fungi. Plasma membrane is present. Nucleus is present. Nuclear membrane is present. Chromatin with histone is present. Number of chromosome per cell depends upon the type of organism. Each chromosome is linear having a centromere with two kinetochores. Nucleoli and Mitotic apparatus is present. Nucleolus is present. Plasmids are rarely present. Mesosome are absent. Mitochondria, Endoplasmic Reticulum, Vacuoles, Lysosomes, Chloroplast, centrioles are present.
