1.1-1.3 study guide Flashcards
Structure
The shape and materials that make up something
Function
How something works/ how it does something
What is the relationship between structure and function?
Structure determines function, so when the structure of something changes, so does the function.
What is an example of structure? (describe)
all of the parts of a paintbrush (bristles, metal thing that holds it together, wooden stick that you hold)
What is an example of a function? (describe)
What a paintbrush is used for (applying paint to a surface)
What is an example of something that is living?
Corn, the mold on bread, bacteria
Is a sea anemone alive?
Yes
What is an example of something is is not living?
A river, soil, a virus, the sun
Is a tornado alive?
No
What is the PMC model of life?
- program (reproduce)
- metabolism (getting and using energy)
- Container (typically cell membrane, it separates it from its environment)
How do you determine if something is alive? (what questions do you ask) (hint: there are three)
- can it reproduce?
- does it have a membrane or containing wall
- can it receive and use energy
What is the level of organization of life?
atom
molecule
organelle
cell
tissue
organ
organ system
organism
population
community
ecosystem
biome
biospehere
What is a molecule?
multiple atoms
What does multiple molecules create?
An organelle
What are organs made of?
Tissues
What is the difference between population, community, ecosystems, biomes, and biosphere?
population- members of the same species
community- different populations that interact in an area
ecosystems- all the different populations that live in an area + abiotic factors
biomes- similar ecosystems around the planet
biospehere- different ecosystems that make up the planet
What is an example of an organelle?
mitochondria
What is E.coli an example of?
A cell
Do you think Coronavirus is alive? Why or why not? Explain.
Viruses like Coronavirus are not considered alive by biologists, while there is a debate over the topic. Viruses do not grow or reproduce by themselves, therefore they are not alive.
What is the relationship between an organelle and a cell?
A cell is made up of multiple organelles
give examples of each:
atom
molecule
organelle
cell
tissue
organ
organ system
organism
population
community
ecosystem
biome
biosphere
examples:
- carbon atom
- H2O
- mitochondria
- E.coli
- stomach tissue
- liver
- nervous system
- red panda
- group of pandas
- forest with frogs and birds
- coral reef
- desert
- earth
