test 1 Flashcards
adaptation
characteristics that help an organism survive and reproduce in its given environment
atom
the smallest part of an element that retains the property of that element
autograph
organisms that make their own food (producers)
binomial system
a way of naming species based on kingdoms
biodiversity
the diversity of species and the interactions that sustain them
cell
the smallest unit of life. Every living thing has at least one cell
cell theory
the cell is the basic unit of life
chromosomes
a structure inside the nucleus of the cell that is made of protein and a single molecule of DNA. They carry information to help a cell grow and reproduce
community
a collection of populations interacting with each other
conclusion
the end of an experiment that includes the validity of the hypothesis based on the experimental evidence
control
the variables that stay the same during the experiment
cytoplasm
a gel-like fluid inside the plasma membrane where other parts of the cell can operate
deductive reasoning
the process of creating a hypothesis about how a certain experiment will come about based on a supported generalization
DNA
a type of molecule that contains the hereditary information for life
domain
the most general ways organisms can be grouped; 3 major categories
element
the substances that form all matter on Earth
energy
the ability to do work
eukaryotic
a type of cell that has an enclosed membrane and nucleus. Generally larger than prokaryotic cells. Membrane enclosed nucleus
evolution
the theory that modern organisms came from preexisting organisms
gene
units of heredity that provide the information necessary to control the cell
experiment
a procedure to test and prove your hypothesis
heterotroph
an organism that obtains nutrients by consuming other organisms
homeostasis
maintaining a stable internal environment
hypothesis
an educated guess based on prior knowledge on how an experiment will come about
inductive reasoning
the process of creating a generalization as a result of concluding observations that support it
kingdom
subdivisions of a domain that help classify specific organisms (fungi, plantae, animalia, etc.)
molecule
combined atoms held together by chemical bonds (ex: H2O)
multicellular
an organism that has multiple cells in it
mutation
mistakes within a DNA cell. Part of evolution
natural causality
the principle that all events can be traced to natural causes
natural selection
the process where organisms use specific traits to help cope with the conditions of the environment
nucleus
most important part of the cell. It controls it and holds all DNA information. only in eukaryotic cells
nutrient
the substances organisms need for energy/growth/to survive
observation
a statement or remark based on your 5 senses
organ
a collection of certain tissue that creates an important art of the body
organelle
a subcellular structure in the cytoplasm that has specific tasks to perform within the cell
organic molecule
Molecules that are primarily made of carbon atoms bonded with other elements and/or other carbon atoms. All living things on earth are composed of organic molecules.
organism
a living thing
organ system
a group of organs that work together to perform tasks/functions (ex. digestion)
photosynthesis
the process of how plants convert sunlight, carbon dioxide, and water into food in the form of glucose and release oxygen
plasma membrane
Membrane in the cell that separates the inside of the cell from the outside made of embedded proteins.
population
a particular group of species living and interacting with one another
prediction
something that you think will happen in the near future with supported data
prokaryotic
A type of cell in bacteria and archaea that lacks a nucleus and membrane-bound organelles.
Genetic material in cytoplasm.
question
a question worded to ask something they don’t know (to ask something unknown)
scientific method
A method to make a scientific fact starting by making a hypothesis and experimenting to either accept, or reject the hypothesis, and re testing.
Consists of multiple operations
scientific theory
explains a certain set of facts or idea about a specific situation or similar situation
species
a group of similar organisms and individuals who have the ability of reproducing and exchanging genes with one another
tissue
a group of cells that have a similar structure and function of a unit
unicellular
consisting of one cell
variable
an element, feature, or factor that is liable to change
