At their simplest, broadest level, living organisms are classified into domains according to whether their cells are nucleated or non-nucleated and according to the structure of their cells' membranes. The domains are Eukarya (nucleated organisms) and two prokaryotic domains differentiated by cell membrane detail (among other things): Archaea and Bacteria.
Domains are further divided into kingdoms. Eukarya, for example, is divided into the plant kingdom, animal kingdom, fungal kingdom and protist kingdom. The protists should actually be classified as many kingdoms due to their diversity. Plants, animals and fungi are differentiated on cell wall structure and cell structure. Plants have cellulose cell walls, fungi have chitinous cell walls and animals lack cell walls. Plants contain chloroplasts, which animals and fungi lack. Animals contain centrioles which plants and fungi mostly lack. Animals and plants are all multicellular whereas some fungi are unicellular (such as Saccharomyces).
Kingdoms are divided into phyla. There are 12 phyla of plants and just over 30 phyla of animals and a few fungal phyla. The singular of phyla is phylum by the way. Through their phyla, plants show increasing sporophyte dominance and decreasing gametophyte dominance. Primitive plants such as bryophytes are gametophyte dominant whereas all other plants are sporophyte dominant, but increasingly so thoughout the evolution of plants, from really dominant bryophyte gametophytes to the really diminutive and shrunken gametophytes of angiosperms. Some of the phyla of plants are: Hepatophyta, Bryophyta/Musci, Anthocerotophyta, Pteridophyta, Equisetophyta, Ginkgophyta, Pinophyta, Cycadophyta, Gnetophyta, Anthophyta.
Note that "kingdom" and "phylum" are major subdivisions (taxa): there are intermediates. In the animal kingdom, there is a distinction between Radiata and Bilateria which are "unranked" taxa, not kingdoms and not phyla but between the two (and not subkingdoms or superphyla either in case you wonder). Radiata contains radially symmetrical animals such as the phyla Cnidaria and Ctenophora (jellyfish + corals and comb jellies respectively). Bilateria contains the bilaterally symmetrical animals which may be further classified as coelomate, acoelomate or pseudocoelomate according to the advancedness of their body cavities. Some bilaterian phyla include Platyhelminthes, Mollusca, Annelida, Arthropoda, Nemertea, Nematoda, Chaetognatha, Sipuncula, Echinodermata, Chordata, Hemichordata and Xenoturbellida.
You see the pattern by now. Division after division in the taxonomic hierarchy: Kingdom, Phylum, Class, Order, Family, Genus, Species. Linnaeus (the "father" of classification) no doubt grouped organisms solely on morphology. Now, we use molecular data and that can refute or confirm morphological hypotheses of classification. Linnaeus grouped on "likeness"/similarity, no doubt oblivious to evolutionary relationship or genetic relationship (Darwin published Origin about a century after Linnaeus did anything useful) and, in those days, species were declared immutable creations. No-one knew of Mendel, no-one knew of Darwin, no-one knew of the concept of monophyly. But, these days, classification must reflect evolutionary relations where groups are monophyletic (a monophyly comprises a common ancestor and all its descendents). Mammals are a monophyly. All platypuses, marsupials and placental mammals all share a common ancestor. Reptiles are techincally not a monophyly. The common ancestor of all reptiles is also the common ancestor of all birds. If one excludes "bird" when one talks of reptiles, trying to say that birds are not reptiles, then "Reptilia" is not a monophyly.
Classification is of course a war and a half. There are those who are disposed to "lumping" and those inclined to "splitting". For example, someone who says a Giant Panda is a "Bear" "lumps" this species in the Family Ursidae. Someone who declares a Giant Panda is too distinct to be an ursid "splits" the Giant Panda into a separate family, Ailuridae. Cats, including lynxes, used to almost all be in the genus Felis. Now, they have been split into many genera. In fact, caracals and lynxes (both lynxes by the common tongue) are split into two separate genera themselves. The same story about cats is similar to the story about albatrosses and sunbirds. Goodness, the battle does go on.
What else can I help you with?
How are living things organized?
Living things are organized into a hierarchy of biological levels from atoms to molecules, cells, tissues, organs, organ systems, organisms, populations, communities, and ecosystems. This hierarchical organization helps to understand the interaction and complexity of living organisms in their environments.
What are the basis of all living things?
All the known living things are water-based. Also all the living things have the following features in common: 1. Living things are highly organized. 2. All living things have an ability to acquire materials and energy. 3. All living things have an ability to respond to their environment. 4. All living things have an ability to reproduce. 5. All living things have an ability to adapt.
How are living things organize?
Living things are organized into a hierarchy, from smallest to largest: cells, tissues, organs, organ systems, and organisms. This organization allows for specialized functions and coordination between different levels to maintain life processes. Each level of organization works together to ensure the survival and well-being of the organism.
How can living organisms remain organized?
They aren't saying things just to say them. Organisms areorganized. Organelles compose cells, cells compose tissues, tissues compose organs, organs compose organ systems. There are many further levels of organization.
What is the biological sciences of activities that all living things carry out?
If you mean the 8 things all living things have in common, they are as follows: 1) All living things are highly organized and contain many complex chemical substances. 2) All living things contain one or more cells. 3) All living things use energy. 4) Living things have a definite form and have a limited size. 5) Living things grow. 6) Living things respond to changes in the environment. 7) Living things can reproduce. 8) Living things eventually die.
How are living organized internally?
Living things are organized internally by there tissues,organs,and organ systems.
How are living things organized?
Living things are organized into a hierarchy of biological levels from atoms to molecules, cells, tissues, organs, organ systems, organisms, populations, communities, and ecosystems. This hierarchical organization helps to understand the interaction and complexity of living organisms in their environments.
How are cells organized into larger and larger groups to help living things survive?
how cells are organized into larger and larger groups to help living things survive
The chemistry of living things is organized around what element?
carbon
How are living things organized in the tree of life?
phylum and breed
Can nonliving things organize?
No, non-living things cannot do things like organize themselves. They may be composed of organized units, such as atoms or molecules, but they don't organize together like living things do.
How are living things organized-?
Living things are classified in a biological classification from the biggest to smallest. The classes include; Kingdom Phylum Class Order Family Genus Species
When was Organized Living created?
Organized Living was created in 1985.
What is Organized Living's population?
The population of Organized Living is 05.
What is the population of Organized Living?
Organized Living's population is 1,000.
What two levels are living things organized in?
KINGDOM ANIMALIA AND KINGDOM PLANTAE? ANIMALS AND PLANTS.
In order to stay organized and perform activities of life what do living things require?
they need energy
