Origin of life
- Earth formed approximately 4.6 billion years ago with a harsh atmosphere of high heat, water vapor, volcanic activity, and no breathable oxygen.
- Early theories on the origin of life included that it began extraterrestrially or through creationism, but the prevailing theory of chemical evolution suggests that organic compounds formed on the early Earth and combined to produce life.
- The Miller-Urey experiment demonstrated that organic compounds like amino acids and nucleotides can form when basic gases like methane and ammonia are exposed to electric sparks simulating lightning, supporting chemical evolution as a viable theory for how life began.

Classification of organism 2n week
This document outlines the hierarchical taxonomic classification system used to categorize organisms, consisting of Domain, Kingdom, Phylum, Class, Order, Family, Genus, and Species. It provides examples for each category and explains that the classification system allows scientists to consistently name and group organisms based on their characteristics and evolutionary relationships. The purpose is to organize the diversity of life and enable communication about different species. The system continues to be refined as new discoveries are made.
Why Do We Classify In Science
The first scientists to classify organisms were Lewis and Clark in the early 1800s as they described hundreds of plants and animals. Classification systems organize information about organisms into groups with consistent naming which facilitates communication among scientists and helps understand organisms' needs. The lowest classification level is species, with humans belonging to the Kingdom Animalia, Phylum Chordata, Class Mammalia, Order Primates, Family Hominidae, Genus Homo, and Species Homo Sapiens. The kingdom level has six main subgroups and the most important reason for classifying is that it allows for efficient communication in science.
Classification of living things
Biological classification involves grouping organisms based on shared characteristics and evolutionary relationships. Organisms are organized into a hierarchy of taxonomic ranks including domain, kingdom, phylum, class, order, family, genus, and species. This system allows organisms to be accurately identified and studied based on their evolutionary relationships and physical similarities.
Living things classification

The document then provides details about the five kingdoms - Monera, Protists, Fungi, Plants, and Animals - including their key characteristics and examples. It also introduces the concepts of binomial nomenclature and discusses how organisms are named scientifically.
Classification of Living Things
- The document discusses classification of living things from the kingdom to the species level. It explains Linnaeus' system of binomial nomenclature and how modern classification is based on evolutionary relationships determined by comparing DNA and RNA.
- The modern systems of classification include five kingdoms, six kingdoms by separating bacteria into Eubacteria and Archaebacteria, and three domains - Archaea, Bacteria, and Eukarya. Each level of classification from domain to species provides more specificity about an organism's evolutionary history.
Chapter 18.1
The document discusses the goals and development of binomial nomenclature and scientific classification systems. It explains that Carolus Linnaeus developed a two-word naming system for species and a hierarchical taxonomy with seven levels (kingdom, phylum, class, order, family, genus, species). The taxonomy aims to organize living and fossil species into meaningful groups based on anatomical similarities and evolutionary relationships. However, traditional classification based only on outward similarities has limitations that modern schemes seek to address.
Phylogenetics: Classification Notes
- There are three domains of life: Archaea, Bacteria, and Eukarya. Archaea and bacteria are prokaryotes lacking nuclei and organelles, while eukaryotes have nuclei and membrane-bound organelles.
- Eukaryotes are divided into four kingdoms: Protista, Plantae, Fungi, and Animalia. Protists are microscopic eukaryotes that may be photosynthetic or heterotrophic. Plants are photosynthetic and multicellular. Fungi are heterotrophic and absorb nutrients. Animals are mobile and ingest food.
- Classification systems have evolved over time based on new discoveries. Early systems grouped by visible characteristics,

Power point presentation on topic Classification -Arunima V.S
Carl Linnaeus developed one of the earliest systems for classifying living organisms in the 1700s. He divided the living world into two kingdoms - plant and animal. Linnaeus proposed a hierarchical classification system with seven levels including kingdom, phylum, class, order, family, genus, and species. This system organized all of Earth's biodiversity and laid the foundation for modern scientific taxonomy.
Lesson plan science
This module introduces biodiversity and how organisms are classified and named. It discusses the variety of living things on Earth and how they are grouped into domains, kingdoms, and species based on their characteristics. Organisms are classified to better understand the relationships between different types of living things and given scientific names to have a standardized system for identifying and discussing organisms anywhere in the world. The module will cover the historical background of classification, current classification systems, and the importance of classifying organisms.
Sandel classification
The document discusses the classification of organisms into kingdoms. It describes the six kingdom system used today: Archaebacteria, Eubacteria, Protista, Fungi, Plantae, and Animalia. Each kingdom is defined by characteristics such as whether its cells are prokaryotic or eukaryotic, whether its members are unicellular or multicellular, and how they obtain nutrition.
UNIT 9 CLASSIFICATION OF LIVING THINGS 1 ESO
The document discusses the classification of living things into scientific kingdoms. It describes the five kingdom system including Monera, Protista, Fungi, Plantae, and Animalia. For each kingdom, there are examples of common organisms provided and brief descriptions of their distinguishing characteristics. The document emphasizes that classification is based on evolutionary relationships and similarities derived from common ancestry rather than physical appearance alone.
Classification power point_with_domain
The document discusses taxonomy, the study of classifying and naming organisms. It does this to bring order to Earth's tremendous biodiversity. Classification is currently based on structural and chemical similarities like DNA that show how closely related organisms are. The taxonomic hierarchy consists of domains, kingdoms, phyla, classes, orders, families, genera, and species. Binomial nomenclature uses a two-word scientific name, with the genus coming first followed by the specific epithet, to uniquely identify each species.
Classifying living things
The document outlines the hierarchical classification system developed by Carolus Linnaeus. It shows the different levels of the classification including kingdom, phylum, class, order, family, genus, and species. Organisms are grouped together based on shared characteristics and each group comes from the one before it, with organisms in the same genus and species being the most closely related.
Biology 18.3
The document outlines the taxonomic classifications of domains and kingdoms. It introduces the three domains of Bacteria, Archaea, and Eukarya. Bacteria contains the kingdom Eubacteria of unicellular prokaryotes with cell walls containing peptidoglycan. Archaea contains the kingdom Archaebacteria of unicellular prokaryotes lacking peptidoglycan in their cell walls. Eukarya contains the kingdoms of Protista, Fungi, Plantae, and Animalia. The six kingdoms of life are Eubacteria, Archaebacteria, Protista, Fungi, Plantae, and Animalia.
Goal 1, unit 1
Taxonomy is the branch of biology that classifies organisms into a hierarchical system of groups based on similarities. There are three domains - Bacteria, Archaea, and Eukarya. Within Eukarya are kingdoms including Plantae, Fungi, and Animalia. Taxonomy groups species into increasingly specific taxonomic ranks like domain, kingdom, phylum, class, order, family, genus, and species. The scientific name for a species includes its genus and specific epithet.
Classification notes
The document discusses the classification of living things from early systems developed by Aristotle and Linnaeus to the modern scientific system. It describes the levels of the modern classification system from domain to species and examples like the two types of cells and the three domains and four kingdoms. Key terms explained include taxonomy, binomial nomenclature, and characteristics used at different levels like phylum, class, order and family.
Unit 11 biodiversity and classification
This document discusses biodiversity and classification of living organisms. It defines biodiversity as the variety of species in an area, including different ecosystems and genetic diversity. It also describes endangered and threatened species. The document then discusses different levels of biological organization and regions called biodiversity hotspots that contain high concentrations of species. It provides examples of indigenous and endemic species. The rest of the document discusses the history of classification systems starting with Aristotle and advancing to the modern 5-kingdom system including Monera, Protista, Fungi, Plantae, and Animalia.
C:\fakepath\teaching lesson classification
This document discusses classification of organisms and the development of modern biological classification systems. It explains that organisms can be classified into groups based on observable characteristics and that the modern system originated with two main kingdoms, plants and animals. Over time, as scientists discovered more types of organisms, new kingdoms like fungi and protista were added to properly classify organisms that did not fit exclusively into plant or animal. The document stresses that classification systems are important tools for organizing knowledge in biology and other fields.
Biodiversity
This document discusses how biodiversity loss can impact ecosystem functioning and processes. It begins by noting that human impacts have dramatically reduced biodiversity at all levels from genes to entire ecosystems. Many ecosystem processes are sensitive to biodiversity declines. Experimental studies show that reductions in biodiversity can decrease plant productivity and increase variability in processes like nutrient levels and plant growth. Maintaining biodiversity is important for preserving ecosystem services that support human welfare, and should be a priority in environmental policies.

The urinary system maintains homeostasis by filtering the blood and producing urine. It is composed of the kidneys, ureters, urinary bladder, and urethra. The kidneys filter waste from the blood to produce urine, which travels through the ureters to the bladder. The bladder stores urine until urination, when it is expelled through the urethra. Together these organs excrete waste from the body while regulating water balance and electrolyte levels in tissues and blood.

Taxonomy is the science of classifying living things. Organisms are grouped based on similarities into a hierarchical system of categories ranging from broad Kingdoms to specific Species. The modern system has three Domains - Archaea, Bacteria, and Eukarya - reflecting evolutionary relationships determined by molecular analysis. Carolus Linnaeus developed the binomial nomenclature system still used today, assigning every species a two-part scientific name describing its Genus and differentiating species. Classification systems continue evolving to best represent the evolutionary history and relationships between all forms of life.

It describes the six kingdoms - Archaea, Bacteria, Protista, Fungi, Plantae, and Animalia - and provides examples and characteristics of organisms from each kingdom. The document also discusses how classification is an evolving field as new discoveries are made.
BIOLOGICAL SCIENCE~origin of life
This document provides information on the origin of life and biological classification. It discusses early theories on abiogenesis and spontaneous generation, as well as experiments by Redi, Spallanzani, and Pasteur that supported biogenesis. Lamarck and Darwin's theories of evolution and natural selection are overviewed. The five kingdom classification system including Monera, Protista, Fungi, Plantae, and Animalia is explained. Various phyla under each kingdom are listed along with examples. Scientific naming conventions and rules are also covered.
Classification Notes
The document discusses biological classification and taxonomy. It describes the five kingdoms of life - Monera, Protista, Plantae, Animalia, and Fungi. Each kingdom is defined by characteristics such as cellular structure, nutrition, and habitat. Classification moves from broadest to most specific, ranking organisms within a kingdom, phylum, class, order, family, genus, and finally species. The human classification of Homo sapiens is provided as an example.
How life is organized 2014
This document discusses biological classification and taxonomy. It begins by outlining the seven characteristics of life and introducing the hierarchical system used to classify organisms into domains, kingdoms, phyla, classes and other groups. The three domains of life are Bacteria, Archaea and Eukarya. Organisms are grouped based on their structural similarities. The document then examines the distinguishing features of prokaryotes and eukaryotes before providing examples of classification for various organisms from bacteria to animals.

Here are the key points about bacteria from the passage:
- Bacteria are the sole members of the kingdom Monera and occur almost everywhere. Many live as parasites in or on other organisms.
- Bacteria are grouped into four categories based on shape: spherical (coccus), rod-shaped (bacillus), comma-shaped (vibrio), and spiral-shaped (spirillum).
- Archaebacteria are a special group that can live in extreme environments like salty areas, hot springs, and marshes. They have a different cell wall structure that allows them to survive in these conditions. Methanogens produce methane.
- Eubacteria, or true bacteria, include cyanobacteria (blue-green
Chapter4-Systematics.ppt
Linnaeus developed the first hierarchical system for classifying organisms in the 18th century based on observable traits. While useful, it did not reflect evolutionary relationships. Modern systematics aims to classify organisms based on their evolutionary history and common ancestry, as revealed by anatomical similarities, genetic data, and the fossil record. Phylogenetic trees illustrate evolutionary relationships and shared ancestors between modern species and are constantly refined as new evidence emerges.

PowerPoint presentation that highlights chapters 13 and 14 in Campbell's Essential Biology (3rd. edition). It can also be used for Miller & Levine's Biology (2006 Ed.) for chapters 15-18.
Mini Beasts – Bugs And More
The document discusses mini beasts like bugs and their roles in ecosystems and food webs. It provides facts about different types of bugs like flies, caterpillars, and butterflies. It also discusses classifying organisms into a taxonomic hierarchy and identifying the main groups of arthropods like insects, arachnids, myriapods, and crustaceans. The document explores food chains and how energy is transferred between producers, consumers, and decomposers. It explains that food webs are more complex than food chains by showing multiple feeding relationships between organisms.
Classifying life
There are over 2 million known species of organisms that are classified into 6 major kingdoms. The document then provides details about the characteristics of each kingdom, including whether organisms are prokaryotic or eukaryotic, unicellular or multicellular, and how they obtain nutrients. It also discusses the scientific naming of species using binomial nomenclature with the genus and species names.

MERCURY GROUP.BHMS.MATERIA MEDICA.HOMOEOPATHY
Mercurius is named after the roman god mercurius, the god of trade and science. The planet mercurius is named after the same god. Mercurius is sometimes called hydrargyrum, means ‘watery silver’. Its shine and colour are very similar to silver, but mercury is a fluid at room temperatures. The name quick silver is a translation of hydrargyrum, where the word quick describes its tendency to scatter away in all directions.
The droplets have a tendency to conglomerate to one big mass, but on being shaken they fall apart into countless little droplets again. It is used to ignite explosives, like mercury fulminate, the explosive character is one of its general themes.
