Professor John Tyler Bonner (1920–2019) spent a lifetime researching the slime molds and created a number of fascinating films in the 1940s to show the life cycle; he mostly studied D. discoideum. In the videos, intelligence appears to be observed as the single cells, after separation, regroup into a cellular mass.
The film describes the life and development of the various types of slime molds with the aid of experts and artists involved in their study. [2] The directors involved Mark Pragnell, an amateur observer of slime mold who studies them in their natural element in the forest. Pragnell appears in several scenes in the film offering his observations ...
Molds are considered to be microbes and do not form a specific taxonomic or phylogenetic grouping, but can be found in the divisions Zygomycota and Ascomycota. In the past, most molds were classified within the Deuteromycota. [5] Mold had been used as a common name for now non-fungal groups such as water molds or slime molds that were once ...
Life cycle. Dictyostelium discoideum is a species of soil-dwelling amoeba belonging to the phylum Amoebozoa, infraphylum Mycetozoa.Commonly referred to as slime mold, D. discoideum is a eukaryote that transitions from a collection of unicellular amoebae into a multicellular slug and then into a fruiting body within its lifetime.
They start as clay sculptures onto which two- (or more) part molds are made in order to reproduce all the details. Then the mold parts are assembled with an armature inside, and they are filled with a liquid material (foam latex, silicone rubber, urethane foam, etc.) that then forms a soft rubbery "flesh" over the skeleton.
Slime molds contribute to the decomposition of dead vegetation; some are parasitic. Most slime molds are terrestrial and free-living, typically in damp shady habitats such as in or on the surface of rotting wood. Some myxogastrians and protostelians are aquatic or semi-aquatic. The phytomyxea are parasitic, living inside their plant hosts.
Organisms that reproduce sexually yield a smaller number of offspring, but the large amount of variation in their genes makes them less susceptible to disease. Many organisms can reproduce sexually as well as asexually. Aphids, slime molds, sea anemones, some species of starfish (by fragmentation), and many plants are examples. When ...
Each cell keeps its individuality even when it forms a stalk and fruiting body to reproduce. [3] Slime molds were originally thought to be in a monophyletic group Mycetozoa , with little distinction between Acrasis and Dictyostelids , however scientists uncovered that they were distinct groups, and eventually that Acrasis was incredibly distant ...
