Chapter 1 Flashcards
5 characteristics of life
- Organization
- Reproduction, Growth & Development
- Energy
- Internal consistency (Homeostasis)
- Evolution
What are Emergent properties
Things or characteristics we see as we move up and down the levels of organization
What are the requirements to be considered alive?
Have to have all of these characteristics:
- Organization
- Uses energy
- Ability to maintain homeostasis (internal consistency)
- Ability to Reproduce, Grow, and Develop
- Ability to Evolve
What is heat
Energy that has been lost
What is Homeostasis
Process by which we maintain our internal consistency for normal function
Ex: eating, shivering, hydration
What are the 2 types of reproduction
Asexual
Sexual
What happens in Asexual reproduction?
Organisms make a copy of them selves with similar genetic make up
What happens in sexual reproduction
Where 2 parents produce an offspring with different genetic make up than the parents’
Evolution is…
The genetic change over time
What is energy needed for?
- To keep organized
- Carry of reactions
- Transportation of molecules
- Maintenance of internal consistency
- Reproduction
What is Taxonomy?
The classification of living and extinct organisms
Taxis (arrangement) nomos (law)
How are organisms grouped
By:
- Characteristics
- Features
- Genetically
Are prokaryotes single cell organisms?
True or Flase
True
What are the two domain types of prokaryotes?
Domain Bacteria
Domain Archaea
Are Eukarya unicellular or multicellular organisms?
Multicellular organisms
What are the 3 Domains of life?
Domain Bacteria
Domain Archaea
Domain Eukarya
What does Prokaryotic mean
The cell does not have a nucleus or any other organelles
What are the kingdoms of the Eukarya domain?
Kingdom Protista
Kingdom Animalia
Kingdom Fungi
Kingdom Plantae
What kingdom is classified as being: an Autotroph and unicellular?
Kingdom Plantae
What kingdom is considered Unicellular or Multicellular and can have autotrophs and heterotrophs?
Kingdom Protista
Kingdom Protista
- Multicellular or unicellular
- Heterotrophs or Autotrophs
- Kind of a catch all for things that don’t fit into the other 3 kingdoms of the Domain Eukarya
What kingdom is considered Multicellular and a Heterotroph (Through ingestion)
Kingdom Animalia
What kingdom is considered mostly multicellular and a heterotroph (through external digestion)
Kingdom Fungi
What is the big difference between Domain Eukarya and Domains Bacteria and Archaea
Domain Eukarya have larger and more complex cells with nuclei
What does a Primary producer do?
They extract energy and nutrients from the non living environment
How does a Consumer gain energy and nutrients
By eating other organisms
How do Decomposers gain energy and nutrients?
From dead organisms and organic waste
Is a Decomposer considered a consumer?
Yes
What is Homeostasis
The process in which we maintain internal consistency for normal functioning
Examples of Homeostasis
- Hydration
- Shivering
- Eating
What are the 8 levels of the Taxonomic Hierarchy?
- D - Domain
- K - Kingdom
- P - Phylum
- C - Class
- O - Order
- F - Family
- G - Genus
- S - Species
Inductive reasoning is
Something you know
Ex: from doing something over and over and knowing the results, experience
Deductive reasoning is
Something you learn or gather knowledge about and apply
What is the Scientific method
The process of examination that is used to explore observations and answer questions
