Change over time Evolution
All living things share a Common Ancestor
"Father" of Evolution Charles Darwin
Ship that Darwin sailed on for 5 years Beagle
Evolution occurs through the process of Natural Selection
Changes that help an organism survive and reproduce Adaptations
The key to evolution Reproduce successfully
Fossils, vestigial structures and comparing organisms all provide what for evolution Evidence
Solidified remains or imprint of a once living organism Fossil
Remnant of a once-useful structure Vestigial Structure
The process by which organisms with favorable traits survive and reproduce Natural Selection
Overproduction, Genetic Variation, Struggle to Survive, and Successful Reproduction are the four stages of Natural Selection
Production of more offspring than will survive Overproduction
Individuals in a population are slightly different Genetic Variation
Individuals compete for resources Struggle to Survive
Change in a gene Mutation
Populations that can produce offspring that can have more offspring are said to be the same Species
The process by which two populations of the same species become so different that they can longer interbreed Speciation
Separation, Adaptation and Division are all possible explanations for Speciation
When a portion of the population is physically isolated from the others due to a mountain, lake, canyons, natural disaster Separation
When a species dies out completely Extinction
Metaphor for the concept of Natural Selection Survival of the fittest
A system of organizing things into groups based on their characteristics Classification
The science of classifying organisms Taxonomy
Largest in the seven levels of classification Kingdom
Smallest in the seven levels of classification Species
First word in the scientific name Genus
Second word in a scientific name Species
A chart with pairs of statements that lead you to the name of an organism Dichotomous key
Type of reproduction that involves an egg and sperm Sexual
Type of reproduction where there is only one "parent" and identical offspring Asexual
Which kingdom has organisms that are only eukaryotic cells and consumers Animal
Which kingdom has organisms that are only eukaryotic cells and producers Plant
Which kingdom contains organisms that are only eukaryotic cells but can be either producers or consumers Protist
Which kingdom contains organisms that are eukaryotic cells and decomposers Fungus
Which kingdom contains the oldest living organisms, prokaryotic cells Archaebacteria
Which kingdom contains common prokaryotic cells Eubacteria
Organisms that eat other organisms Consumers
Organisms that make their own food Producers
Organisms that break down nutrients in dead organisms Decomposers
A new part of an organism grows off the old one Regeneration
A part of an organisms falls off and grows into a new one Budding
Which protist uses flagellum for movement, is green and makes its own food Euglena
Which protist uses pseudopods for movement Amoeba
Which protist uses cilia for movement Paramecium
Sexual reproduction of the paramecium Conjugation
Asexual reproduction of the amoeba, euglena, algae Binary fission
Rod shape bacteria bacillus
Round shape bacteria cocci
Spiral shape bacteria Spirilla
Extreme hot conditions where you may find archaebacteria Hotsprings
PassFather of genetics-used pea plants to study passing of traits Gregor Mendel
Making of sex cells Meiosis
Number of chromosomes in a sex cell 23
Contains genes Chromosomes
Contains DNA Gene
Two forms of every gene Allele
Form of the gene that is always expressed Dominant
Form of the gene that is expressed only when both alleles are recessive Recessive
Organisms physical appearance Phenotype
Inherited combination of genes Genotype
Two different forms of an allele (hybrid) Heterozygous
Two of the same alleles (pure) Homozygous
Probability Ratio
Used to visualize all of the possible combinations of alleles from the parents Punnett Square
A family tree of traits Pedigree
ing of traits from one generation to the next Heredity
What is the female structure of a flowering plant Pistil
What is the male structure of the flowering plant Stamen
Which part of the stamen makes pollen Anther
What is the structure that holds the anther up Filamant
What is the structure on the top of the pistil stigma
What is the structure at the base of the pistil ovary
What structure becomes a seed when fertilized ovule
When the ovary is fertilized it becomes a fruit
The movement of sperm from the anther to the stigma is called pollination
When the egg and sperm unite it is called fertilization
Inside pollen you will find sex cells
After fetilization the ovary becomes fruit
Consumer that eats meat only Carnivore
Consumer that eats plants only Herbivore
Consumer that eats both plants and animals Omnivore
Consumer that eats dead animals Scavenger
Group that breaks down dead organisms Decomposer
Group that makes its own food Producers
Group that eats other things Consumers
Factors in the environment that are alive Biotic
Factors in the environment that are not alive Abiotic

System that transports materials around the body Cardiovascular
System that allows for an exchnage of gases in the body Respiratory
Ssytem that cleanses the blood Urinary
System that breaks down food Digestive
System that regulates hormones Endocrine
