Chapter 1: View Of Life Flashcards
What are the 6 basic characteristics of all living organisms?
All living things Organized, Acquire materials and energy, are capable of homeostasis, respond to their environment, reproduce and develop, & Adapt.
List the organization from smallest to greatest
Atom, Molecule, Cell, Tissue , Organ, Organ System, Organism, Species, Population, Community, Ecosystem, Biosphere
What key words go into the Aquiring of materials and energy?
Energy, Metabolism, & Photosynthesis.
What is the definition of Energy?
The ability to do work.
What is the definition of Metabolism?
All chemical reactions that occur.
What is the definition of Photosynthesis?
Process that transforms solar energy into chemical energy.
Where is energy stored?
In organic molecules.
Explain homeostasis.
The ability to maintain “biological balance”
What are certain biological balance traits in homeostasis?
- Temperature
- Moisture level
- Acidity
Explain adaptation.
modifications that make organisms better suited to their environment.
What is a the definition of an Atom?
Smallest unit of an element composed of electrons, protons, and neutrons.
What is a the definition of a Molecule?
Union of two or more atoms of the same or different element.
What is a the definition of a Cell?
The structural and functional unit of all living organisms.
What is a the definition of a Tissue?
A group of cells with a common structure and function.
What is a the definition of an Organ?
Composed of tissues functioning together for a specific task.
What is a the definition of an Organ System?
Composed of several organs working together.
What is a the definition of an Organism?
An individual; complex individuals contain organ systems.
What is a the definition of a species?
A group of similar, interbreeding organisms.
What is a the definition of a population?
Organisms of the same species in a particular area.
What is a the definition of a Community?
Interacting populations in a particular area.
What is a the definition of an Ecosystem?
A community plus the physical environment.
What is a the definition of a Biosphere?
Regions of the earths crust, water, and atmosphere inhabited by living organisms.
List taxa from most inclusive to most exclusive.
Dumb. King. Phillip. Came. Over. For. Great. Sex.
or
Domain. Kingdom. Phylum. Class. Order. Family. Genus. Species.
What are the rules when using binomial nomenclature?
- It is all italicized or underlined.
- The first word (genus) is capitalized while the second one (species) is lowercase.
Example: Homo sapiens or Homo sapiens
List the three domains of life. Which domain(s) have a membrane-bound nucleus?
Bacteria, Archaea, Eukarya
Eukarya has a membrane-bound nucleus.
What are the 4 supergroups of Domain Eukarya?
Protist, Plant, Fungi, Animalia.
What does it mean to be Prokaryotic?
Does not contain a membrane-bound nucleous.
What does it mean to be Eukaryotic?
To have a membrane-bound nucleus.
What are some distinguishable fungi?
Mold and mushrooms
What supergroups can photosynthesize?
Protists and Plant.
What are the steps of the scientific method?
- Observe
- Formulate a hypothesis
- conduct an experiment
- conclusion
Then, scientific publication/theory
What type of reasoning is formed while creating a hypothesis?
Inductive Reasoning
What kind of reasoning is formed when designing an experiment?
Deductive reasoning
What are the 4 keywords in the experimental stage of the scientific method?
Experimental Variable, Controlled Variable, Experimental group, & Controlled Group
Who is the experimental group?
The group that is receiving the treatment or experimental variable?
Who is the controlled group?
The group that does not receive treatment.
What are the controlled variables?
The variables remain constant throughout the controlled group and experimental group.
