Study Notes
Basic Organism Definitions
- Organism: Any living thing.
- Multicellular: Composed of many cells, usually larger organisms with various bodily functions for survival.
- One-Celled or Single-Celled: Consists of a single cell, typically smaller organisms with fewer functions necessary for survival.
Classification Concepts
- Classification: Organizing living things into groups based on similarities.
- Taxonomy: The scientific study of classifying living organisms.
- Binomial Nomenclature: Two-part scientific naming system consisting of genus and species names, developed by Carolus Linnaeus.
Classification Hierarchy
- Classification involves seven taxon levels from largest to smallest:
- Kingdom
- Phylum
- Class
- Order
- Family
- Genus
- Species
Kingdoms of Life
- Plant Kingdom: Multicellular organisms that obtain energy through photosynthesis (e.g., trees).
- Animal Kingdom: Multicellular, mobile organisms that consume other living beings (e.g., fish).
- Monera/Bacteria Kingdom: Unicellular organisms without a nucleus, crucially abundant on Earth (e.g., bacteria).
- Protist Kingdom: Includes both unicellular and multicellular organisms with varied modes of nutrition (e.g., algae and amoeba).
- Fungi Kingdom: Multicellular, non-moving organisms that absorb nutrients from other organisms (e.g., mushrooms).
Characteristics of Living Organisms
- Genus: A classification level that groups similar organisms (e.g., dogs and wolves).
- Species: The smallest classification unit, representing one specific organism.
- Microscope: A tool used to magnify tiny organisms for study.
Distinctive Features of Groups
- Bacteria Shapes: Includes rod-shaped, ball-shaped, and spiral-shaped categories.
-
Types of Protists:
- Algae: Plant-like and photosynthetic organisms.
- Protozoans: Animal-like, often motile and acquire nutrients from environment or prey.
- Fungi Types: Includes molds, mushrooms, and sac-fungi.
- Plants: Multi-celled organisms containing chloroplasts for photosynthesis (e.g., trees, flowers).
- Animals: Multi-celled, energy-acquiring organisms that feed on others (e.g., mammals, fish).
Classifying Organisms
- Classifying: Grouping organisms based on similarities to enhance understanding and relationships.
- Changing Ideas About Classification: Development of microscopes in the 1600s allowed discovery of new organisms and subsequent revisions in classification.
Human Classification
-
Classification of Humans:
- Kingdom: Animalia
- Phylum: Chordata
- Class: Mammalia
- Order: Primates
- Family: Hominidae
- Genus: Homo
- Species: Sapiens
Example Classification of Monkeys
-
Classification of Monkey:
- Kingdom: Animalia
- Phylum: Chordata
- Class: Mammalia
- Order: Primates
- Family: Cercopithecidae
- Genus: Macara
- Species: Sylvanus
Additional Facts
- Bristlecone Pine Tree: Known as the oldest living tree, estimated to be 4,900 years old, predating the first Egyptian pyramid construction. Found in Nevada.
