PLAY
Properties of living things
Order, Regulate, Grow and Develop, Obtain and use energy, Respond to the environment, Reproduce, Evolve
Order
Cells, tissues, organs, organ systems, organism
Regulate
Organisms can control their internal environment regardless of their external environment
What controls growth and development
The sequence of DNA
How organisms obtain and use energy
either by consuming other organisms or photosynthesis in the case of plants
Respond to the environment
Organism will react to stimuli imposed by the environment
Reproduction
Will make more of its own kind
Evolution
Change in the genetic makeup of a population over time
Biosphere
The entire portion of the Earth inhabited by life
Ecosystem
All living things and their interaction with their environment
The difference between nutrients and energy in an ecosystem
nutrients cycle through organisms but energy flows through organisms, ends up being lost as heat and does not return to the system
Population
a group of organisms of the same species that are living together in the same area at the same time
Similarities of all cells
contain DNA and ribosomes, have a membrane surrounding them, came from other cells
Multicellular
an organism with many cells
Unicellular
an organism made up of one cell
Major difference between a prokaryotic and eukaryotic cell
a nucleus and membrane bound organelles
Gene
A segment of DNA that codes for a polypeptide
Genome
The entire amount of genetic information that an organism inherits
Taxonomy
The branch of biology that names and classifies species
The three Domains
Bacteria, Archaea, Eukarya
The four Kingdoms of Eukarya and their properties
Plantae, Fungi, Animalia, Protista
Plantae
produce their own sugars and other food by photosynthesis
Fungi
mostly decomposers, digest dead organisms
Animalia
obtain food by ingesting other organisms
Protista
generally unicellular group that live in water
Fossils
remains of once living organisms
The name of Darwin's publication
On the origin of species by means of natural selection
The three stages of Natural Selection
Overproduction and competition, individual variation is passed from generation to generation, unequal reproductive success
Adaptation
a characteristic that allows a species to be better suited to their environment
Artificial selection
Selective breeding of domesticated plants and animals by humans
