Biology Module 1 Flashcards
Irreducible complexity
When a system is made up of several interacting components, each of which is necessary for the system to function, and none of which can be made by modifying an already-existing component.
Metabolism
The sum of all chemical reactions occurring in an individual cell to sustain life.
Catabolism
The chemical reactions occurring in an individual cell that break down complex molecules into simple ones, releasing energy that the organism can use.
Anabolism
The chemical reactions that build complex molecules from simple ones, usually requiring the input of energy.
Homeostasis
The ability of an organism to maintain a constant internal environment.
Symbiosis
A long-term relationship between organisms of different species.
Asexual reproduction
A mode of reproduction in which the offspring comes from only one organism.
Sexual reproduction
A mode of reproduction which combines genetic information from a male individual and a female individual to produce offspring.
Differentiation
The process by which a cell becomes specialized to perform a specific set of tasks.
Taxonomy
The science of classifying things, such as organisms.
Prokaryotic cell
A cell without organelles.
Eukaryotic cell
A cell with organelles.
Energy
The ability to do work.
Producers
Organisms that can produce energy-rich molecules as their food source.
Consumers
Organisms that must eat other organisms for food.
