Organism- a complete and entire living thing
Species- organisms of the same type
6 Themes
1) Evolution- species change over time
adaptations
natural selection
2) Reproduction and inheritance
DNA
Gene
offspring
Sexual reproduction
Asexual reproduction - clone
Is reproduction necessary? for individual? for species?
3) structure and function-
anatomy
physiology
Form Follows Function
organisms made of cells- smallest unit of life
unicellular organisms
multicellular organisms
multicellular organisms grow from one cell to many- development-
during development, cells become different from one another- differentiation
development stops when organism reaches maturity- ability to reproduce
organisms grow by assilmilation- take in materials and change them into their own iving material
4) Homeostasis - Organisms maintain a stable internal environment
Stimulus / response
organisms respond to the environment - often to maintain homeostasis
behavior- complicated responses to the environment
5) Energy Use-
all organisms require energy
autotrophs capture energy from the environment and use it to make food
heterotrophs eat other organisms to get food for energy
both autotrophs and heterotrophs "burn" food to release the energy
most autotophs use sunlight to make their food- photosynthesis
Metabolism - the sum of all the processes in an organism that involve energy
6) Ecology- study of the relationship among organisms. A community of interdependent organisms is called an ecosystem
