Study of life Flashcards
What are common characteristics shared by all living things?
Growth and development
Regulation
Reproduction
Responsiveness
Metabolism
Sum of all reactions that occur within the body
Anabolism
Small molecules join to form larger molecules
Catabolism
Large molecules broken down into smaller molecules
Energy
The capacity to do work.
How do plants get energy?
They produce it.
How do animals get energy?
They consume it by eating plants or other animals
Autotrophs or producers
Make their own food
Heterotrophs or consumers
Depend on food energy in autotrophs
Decomposers
Heterotrophs that break down decaying material for energy
Growth
Increase in mass of an organism
Development
Increased specialization
Movement
Can be for an organism
Can be for an individual cell
Responsiveness
Ability to sense and react to stimuli
Stimuli
Change in the environment
In response, cells adjust to try and maintain a stable environment
Homeostasis
Maintaining (regulating) a stable internal environment
Allow complex organization and efficiency
Reproduction
Process by which new living organisms are produced
Asexual and Sexual
Chemical level
Atoms and molecules
Cellular level
Forms based on interactions between atoms and molecules
Organismal level
Interactions between cells
