Bio 11: Examples from 6 Kingdoms, and their descriptions…
Animalia:
-Class Reptilia: Thorny Devil Lizard (Moloch horridus)
Reptiles, including the thorny devil lizard, are tetrapod animals in the class Reptilia (comprising today’s turtles, crocodilians, snakes, amphisbaenians, lizards, tuatara, etc.)… Reptiles are vertebrates (they have backbones), their bodies are completely covered in scales, they are cold-blooded, produce shelled eggs or bear live young (all species fertilize eggs internally though), and all species of reptiles have at least one lung (breath). They are eukaryotic, multicellular, and are heterotrophs.
-Class Mammalia: Cotton-top Tamarin (Saguinus oedipus)
Mammals, including the cotton-top tamarin, are vertebrate animals and are characterized by the presence of mammary glands which in females produce milk for feeding their young, a neocortex, fur or hair, and three middle ear bones. They are warm-blooded, born live (only two hatching from eggs), and are mainly “terrestrial” animals (bats are the only mammals that fly). They are also eukaryotic, multicellular, and are heterotrophs.
Plantae:
-Class Gnetopsida: Welwitschia Mirabilis
Gnetopsida (gnetophytes), including the welwitschia mirabilis, have vessel elements which set them apart from other gymnosperms: a system of conduits that transport water within the plant, similar to those found in flowering plants. Gnetopsida (gnetophytes) only consists of three, highly varied, genera. The welwitschia mirabilis is considered a living fossil- “following germination, the two cotyledons (seed leaves) give rise to two true leaves. Those leaves continue to grow throughout the life of the plant reaching upwards of 6 meters, and no new leaves are produced.”-https://en.wikipedia.org/wiki/Gnetophyta. Their common traits are few and far between, only having the presence of enveloping bracts, as well as a micropylar projection of the outer membrane of the ovule that produces a pollination droplet, in common. They are also eukaryotic, multicellular, and are autotrophs (the only gymnosperm to be able to use CAM photosynthesis to feed).
-Class Dicotyledons: Baobab trees (Adansonia)
Dicots (Dicotyledons), are any member of the flowering plants with a pair of leaves in the embryo of the seed, including the baobab tree. There are about 175,000 known species of dicots: most commonly including (but not limiting too) garden plants, shrubs, trees, and broad-leafed flowering plants (magnolias, roses, geraniums, and hollyhocks). Certain distinguishing traits known about the dicot class are that they have embryos with two cotyledons, pollen with three furrows (or pores), flower parts in multiples of four (or five), their major leaf veins reticulate, their stem vascular bundles in a ring, their roots develop from the radicle, and a secondary growth can often become present. Dicots, baobab trees, and Plantae are all eukaryotic, multicellular and autotrophs.
Archaebacteria:
-Class Methanobacteria: Methanobrevibacter smithii
Methanobacteria, including the Methanobrevibacter smithii, are Methanogens (microorganisms that produce methane as a metabolic byproduct in hypoxic conditions). Both methanobacteria and the Methanobrevibacter smithii have unicellular, prokaryotic cell types and are autotrophic. “Methanobrevibacter smithii is the predominant archaeon in the human gut. M. smithii has a cocobacillus shape. It plays an important role in the efficient digestion of polysaccharides by consuming the end products of bacterial fermentation.”-wikipedia, which also works with the methanobacteria class, as they “can be used in biomass conversion as well as energy production through Anaerobic digestion (AD) process.”
-Class Bacilli: Alicyclobacillus
Bacilli, including Alicyclobacillus, are a taxonomic class of bacteria that includes two orders, Bacillales and Lactobacillales, which contain several well-known pathogens as well. The bacilli class, Alicylobacillus, and Archaebacteria (can) all have unicellular, prokaryotic cell types, and are autotrophic. The Alicylobacillus bacteria is also part of the thermophile group (within the Archaebacteria group). “Alicyclobacillus is a genus of Gram-variable, rod-shaped, spore-forming bacteria. The bacteria are able to grow in acidic conditions, while the spores are able to survive typical pasteurization procedures.”-Wikipedia, which also coincides with the very meaning of bacilli: rod-shaped.
Eubacteria:
-Class Bacilli: Streptococcus pneumoniae
“Eubacteria are typically classified into five different phylums: Chlamydias, Cyanobacteria (Blue-green
algae), Gram-positive bacteria, Proteobacteria, and Spirochetes”-biologydictionary.net: Streptococcus pneumoniae are a gram-positive member of the Streptococcus genus, responsible for the majority of community-acquired pneumonia. Streptococcus pneumoniae, bacilli, and Eubacteria (can) all have unicellular, prokaryotic cell types, and are heterotrophic. Streptococcus pneumoniae is a part of the Eubacteria kingdom as it is a prokaryote, and it reproduces asexually as most Eubacteria does
-Class Gammaproteobacteria :E. Coli (Escherichia coli)
“Eubacteria are typically classified into five different phylums: Chlamydias, Cyanobacteria (Blue-green
algae), Gram-positive bacteria, Proteobacteria, and Spirochetes”-biologydictionary.net Gammaproteobacteria, including E. Coli, are a Gram-negative, facultative anaerobic, rod-shaped, coliform bacterium, and is commonly found within the lower intestine of healthy warm-blooded organisms. E.Coli is a proteobacteria, making it belong to the Eubacteria domain. E.Coli, Gammaproteobacteria, and Eubacteria (can) all have unicellular, prokaryotic cell types, and are heterotrophic.
Protists:
-Class Florideophycaeae: Irish Moss (Chondrus crispus)
Florideophycaeaes, including the irish moss, are an assemblage of red algae sharing different characteristics including (but not limited too) the presence of tetrasporangia and a filamentous gonimoblast, they often have a multicellular thallus (with apical growth), they have pit connections, and cells with multiple nuclei and plastids. Certain species can be used for food, or gels and additives in food and cosmetic products. They are eukaryotic, mainly unicellular (with a few exceptions), and can either be autotrophic or heterotrophic- although the Irish Moss is multicellular and is a photosynthetic autotroph.
-Class Heterolobosea: Brain-Eating Amoeba (Naegleria fowleri)
Heteroloboseas, including the brain-eating amoeba, are known as amoeboflagellates. They generally have a three-phase asexual life cycle, centered on trophic amoebae that can reversibly transform into flagellates (some of which undertake phagocytosis and/or division) and cysts. Within the class exists around 150 heterotroph species, including the brain-eating amoeba. The brain-eating amoeba is a single-celled living organism, commonly found in warm freshwaters such as lakes, rivers, and hot springs and soil. It is commonly known as a shapeshifting amoeboflagellate excavata, because of the way it can change shape. It’s called “brain-eating amoeba” because as it exists in bodies of water (including ill-chlorinated pools), it can travel up the nose into the brain, and the amoeba will start to destroy the brain tissue, which results in brain swelling and usually death (CDC).
Fungi:
-Class Heterobasidiomycetes: Cloud Ear Fungus/Black Fungus (Auricularia polytricha)
Heterobasidiomycetes, including the cloud ear fungus, frequently have large irregularly shaped pores and
sterigmata that can self-replicate – a process where a spore gives rise to a sterigma and a new spore, which is then discharged as if from a normal basidium. Heterobasidiomycetes include jelly fungi, smuts and rusts, belong to the larger division/phylum of basidiomycetes. Cloud ear fungus is an edible jelly fungus, putting it within the Heterobasidiomycete category. It usually grows on trees in mountainous regions, is a gray-brown colour, and is most often used in asian cooking. The cloud ear fungus, Heterobasidiomycetes, and Fungi are all generally multicellular, eukaryotic and heterotrophs- and all require oxygen to survive.
-Class Pezizomycetes: Scarlet Cup (Sarcoscypha coccinea)
The spore-producing/releasing bodies of Pezizmycetes are typically disk-like, bearing on their upper surfaces a layer of cylindrical spore-producing cells, from which the spores are forcibly discharged. The fungus grows on decaying sticks and branches in damp spots on forest floors, and the cup-shaped bodies appear during the cooler months of winter and early spring. Molliardiomyces eucoccinea is the name given to the “imperfect form” of the fungus that lacks a sexually reproductive stage (typically reproduces through mitosis). The scarlet cup, Pezizomycetes and fungi are all generally multicellular, eukaryotic and heterotrophs- and all require oxygen to survive.
