1. Evolution & Taxonomy Unit Review
Practice your vocabulary

2. Diversity
The variety of organisms that live on Earth, each adapted to survive its habitat OR…
All the species on the planet

3. Adaptation
A characteristic, body structure or behavior that helps an organism survive in its habitat

4. Variation
Differences among individuals of the same species

5. What are 2 sources of variation?
Mutation
Sexual reproduction

6. Evolution The process by which a species changes over time
Natural selection over time is one way that evolution happens

7. Natural Selection
The process in which organisms that are better adapted to their environment survive longer, reproduce more often, and pass their genes on to the next generation
It is one way that evolution can happen
Our butterfly lab simulated natural selection for camouflage

8. Mutation A change in the DNA sequence or chromosomes of an organism
New alleles are produced by mutation

9. Sexual Reproduction
A type of reproduction that involves genetic information from 2 parents
Offspring are a new combination of genes.

10. Asexual Reproduction
A type of reproduction that requires only 1 parent
It produces offspring that are identical to the parent.

11. Extinction
Organisms that are not well adapted to their environment may die and not get to reproduce

12. Taxonomy
The study of how living things are grouped

13. Autotroph
An organism that can make its own food like a plant or algae

14. Heterotroph
An organism that cannot make its own food like an animal or fungus

15. Prokaryote
An organism that does not have a membrane-bound nucleus (No nucleus)

16. Eukaryote
An organism that has a membrane bound nucleus (Has a nucleus)

17. Classify
To sort organisms based on similarities and differences

18. Dichotomous Key
A series of paired statements that helps indentify an organism

19. Lithosphere Solid rigid layer of Earth’s crust and upper mantle
The tectonic plates are part of the lithosphere

20. Asthenosphere Hot fluid portion of the upper mantle
The lithosphere floats on the asthenosphere
The movement in the asthenosphere due to the “convection currents” cause the lithosphere to move

21. Theory of Plate Tectonics
States that the Earth’s surface is made up of huge plates that are in constant motion
It explains the following:
Continental drift
Seafloor spreading
Deep ocean trenches

22. Theory of Plate Tectonics
How does this theory explain where earthquakes and volcanoes tend to occur?
Earthquakes and volcanoes tend to happen where 2 plates meet

23. Layers of the Earth
Which layers are the lines pointing to?

24. Crust
Mantle
Outer Core
Inner Core
