Study Notes
Characteristics of Life
- Biology is the study of life.
- Living organisms are organized, meaning they are composed of cells.
- Living organisms respond to stimuli, such as the sunflower turning towards the sun.
- Living organisms grow and develop, increasing in size and complexity.
- Living organisms adapt to their environment, which can be seen in the diversity of life on Earth.
- Living organisms regulate their internal environment, maintaining a stable state called homeostasis.
- Living organisms process energy, which is necessary for all life processes.
Levels of Organization
- The basic unit of matter is the atom, which combines to form molecules.
- The smallest unit of life is the cell, which can be either prokaryotic or eukaryotic.
- DNA is a macromolecule, a complex molecule important for life.
- Cells combine to form tissues, which are groups of cells with similar structure and function.
- Tissues work together to form organs, which carry out specific functions.
- Organs make up organ systems, which are groups of organs that work together to carry out general functions.
- All individuals of the same species living in a particular area form a population.
- Different populations living in the same area form a community.
- A community and the physical environment in which it lives make up an ecosystem.
- The biosphere encompasses all living organisms and their physical environment.
Diversity of Life
- Evolution is the source of the diversity of life on Earth.
- Species are the basic unit of evolution.
- Three domains contain all living organisms: Eukarya, Bacteria, and Archaea.
- Eukarya include plants, animals, fungi, and protists.
- Bacteria and Archaea are single-celled prokaryotes.
Taxonomy
- Taxonomy is the branch of biology concerned with naming, identifying, and classifying organisms.
- The hierarchical system of taxonomy arranges organisms into categories from lowest to highest: species, genus, family, order, class, phylum/division, kingdom, and domain.
- The lowest level, species, is the only category that has a real existence.
- The system of binomial nomenclature, introduced by Carolus Linnaeus, uses a two-part name for each species: genus and species.
- In binomial nomenclature, the genus is capitalized, both genus and species are written in italics, and genus is written first, then species.
Taxonomy Examples
- Coconuts belong to the genus Coco and species Nucifera.
- Mangoes belong to the genus Mangifera.
- Dogs, lions, and snakes belong to the phylum Chordata and the kingdom Animalia.
