Life vs Non-Life
The fundamental building block of life.
What is a cell?
The theory that living things could suddenly, and randomly, arise from non-living materials.
What is spontaneous generation?
An organism that is able to store energy within molecules using energy from the sun through the process of photosynthesis.
What is a producer?
Process of determining if experimental results are consistent with a theory.
What is review/analysis?
What is an organism?
Any event that evokes a response from an organism.
What is a stimulus?
The theory that the first living cell came from non-living material, but thereafter cells have arisen from other cells.
What is abiogenesis?
An organism that breaks down organic matter.
The best model or explanation we have at present for a body of facts, providing the means for producing new hypotheses.
What is a theory?
The fundamental unit of matter.
What is an atom?
A dynamic, continuous stimulus/response pattern that allows an organism to stay within a variety of life-sustaining parameters.
What is homeostasis?
Boiled gravy in sealed tubes for 1 minute and showed that organisms appeared to come from non-living material, supporting spontaneous generation.
Who is Needham?
An organism that must obtain its energy by consuming the cells of other organisms.
What is a consumer?
A testable, informed prediction, based on a theory, or what will happen under certain circumstances.
What is a hypothesis?
Used three different containers with raw meat. One was left open, one was completely sealed, and one was covered with an air-permeable covering. Maggots grew on the exposed meat, nothing grew on the sealed meat, and fly eggs and maggots grew on the container with the permeable covering. Supported the belief that life comes from life.
Who is Redi?
The six characteristics possessed by all living things.
What is: composed of cell and operate on many levels of organization; metabolize; grow, develop, and reproduce; use and transmit genetic information; respond; adapt?
The theory that unicellular organisms can continuously form out of non-living materials according to natural law.
What is archebiosis?
A group of multiple species that occupies a particular geographical region.
What is a community?
A statement, backed up by evidence, that is correct as far as we know.
What is a fact?
The sum total of all the chemical reactions in a cell or organism.
What is metabolism?
What a cell must contain in order to be the fundamental building block of life.
What are: organelles, genetic material, and a membrane?
Addressed previous experimental errors and designed a special swan-necked flask that allowed for air to pass into the flask but kept out dust. Also tipped over the flask, and broke off the neck of the flask to determine if organisms could grow in a boiled broth. Results supported the theory that all life comes from previously existing life.
Who is Pasteur?
A single species living in a particular geographical region at the same time.
What is a population?
Word we NEVER use when reporting the results of an experiment.
What is prove?
Sealed tubes/flasks and boiled broth/gravy for an hour to show that organisms could not spontaneously generate, and to show that experimental errors were the reason why a previous scientist yielded results that supported spontaneous generation.
Who is Spallanzani?
