Multicellular organism increase in size without its limitations. They can have longer lifespans as they can continue living when individual cells die. Multicellularity also permits increasing complexity by allowing differentiation of cell types within one organism. Multicellular organism Multicellular organisms are organisms that consist of more than one cell, in contrast to unicellular organisms. All species of animals, land plants and most fungi are multicellular, as are many algae, whereas a few organisms are partially uni- and partially multicellular, like slime molds and social amoebae such as the genus "Dictyostelium". Multicellular organisms arise in various ways, for example by cell division or
Aerobic organism Aerotolerant organisms must continue fermentation in the presence of oxygen. A good example is the oxidation of glucose (a monosaccharide) in aerobic respiration. Oxygen is used during the oxidation of glucose and water is produced. This equation is a summary of what happens in three series of biochemical reactions: glycolysis, the Krebs cycle, and oxidative phosphorylation. Aerobic organism An aerobic organism or aerobe is an organism that can survive and grow in an oxygenated environment. In contrast, an anaerobic organism (anaerobe) is any organism that does not require oxygen for growth. Some anaerobes react negatively or even die if oxygen
