Study Of Life Unit Test Flashcards
List and explain the characteristics of life (short and multiple choice)
Made up of Cells - Made of one or more cells
Organized - Beginning as an atom or molecule and increasing in complexity
Evolutionary adaptation - Changes occur over time that help the species survive
Response to the Environment - Reacts to internal and external stimuli (responses)
Regulation - All organisms keep internal conditions stable via homeostasis EX) Body temperature
Energy processing - Energy is required to live (Food, Sunlight)
Reproduction - Reproduces and passes down traits to the next generation
Growth and development - Increases in mass and gains new abilities
What are the four main differences between the scientific and indigenous perspectives of life? (short)
- indigenous see their relationship as belonging to the land.
- indigenous coexist with plants and animals.
- Indigenous beleive non living things are alive, have been alive or will be alive (rocks, water).
- indigenous believe life is connected while scientific believes life is interdependent
In Cree culture, what is the difference between animate and inanimate? (Multiple choice)
Animate: Something that is living (With spirit)
Inanimate: Something that is not living (Without spirit)
According to the characteristics of life are viruses alive? Explain. (Short)
According to the characteristics of life, viruses are not alive as they are not made of cells, do not grow, cannot keep themselves in a stable state, and cannot make their own energy.
Define Abiogenesis. (Multiple choice)
Abiogenesis is a theory that non-living things can transform into living things spontaneously. Another term for this is spontaneous generation
Define Biogenesis. (Multiple choice)
The process where life arises from similar life forms
What did Artistotle believe? What observations did he make to support Abiogenesis? (Multiple choice and short)
Aristotle believed in Abiogenesis, He observed wormlike maggots appearing on meat if it was left out for too long, and after rain frogs, insects, and plants seemed to materialize from the dried-out mud of ponds
Describe in detail Francesco Redi’s experiment with jars of meat. (Multiple choice and short)
4 Jars, meat inside. Half of the lids were open, while the others were closed.He found maggots in the open jars He then did a second Experiment where he used mesh over the jars and found maggots on top of the mesh.
Describe in detail Louis Pasteur’s experiment with the broth and the swan neck flasks. (Multiple choice and short)
He put broth inside the swan-necked flasks, the flasks were designed to allow air to enter the flask but prevented dust and microorganisms from directly reaching the broth inside. He then boiled the broth to kill any existing microorganisms. After he left the flask out, exposed to the air. Over time he observed that no microorganisms grew in the broth, despite being exposed to air. The curved part of the flasks prevented any microorganisms from entering
Describe the experiment that Stanley Miller and Harold Urey performed. (Multiple choice)
They attempted to replicate the conditions of Earth’s early atmosphere and oceans to test whether organic molecules could be created abiogenically
What was the theory of Lynn Margulis? (Multiple choice)
the endosymbiosis theory is the theory where the mitochondria, the photosynthetic plastids and basal bodies of flagella were once free living prokaryotic cells
What technology has changed our understanding of the world and how? (Short)
Microscopes have changed our understanding of the world by allowing us to understand what molecules and cells are.
Who was the first person to see a “cell”? (Match)
Robert Hooke
Who was the first person to see a living cell? (Match)
Anton Van Leeuwenhoek
Who proposed that all plants are made of cells and that cells make up tissues? (Match)
Matthias Schleiden
