Characteristics of Living things
All living things are made of these smaller living units.
Cells
The mistaken idea that living things arise from nonlinving sources.
Spontaneous Generation
A group of similar organisms that can mate and produce offspring and their offspring can also mate and reproduce.
Species
Single-celled prokaryotes with no nucleus that produce toxins that can make people sick.
Bacteria
Organisms that can make their own food.
Autotrophs
The most common chemical in cells.
Water
The type of reproduction in which an organism creates an identical offspring with only one parent.
Asexual
A group of similar, closely-related organisms.
Genus
Cannot be classified as animals or plants; most are harmful parasites.
Protists
Organisms that must feed on others.
Heterotrophs
Change that leads to maturity.
Development
They type of reproduction in which two parents combine their DNA to create an offspring.
Sexual
The naming system developed by Linnaeus in which each organism is given a unique, two-part scientific name.
Binomial Nomenclature
A tiny, nonliving particle that reproduces inside a living host cell.
Virus
The maintenance of stable internal conditions.
Homeostasis
Any change or signal in the environment that can make an organism react.
Stimulus
This scientists disproved spontaneous generation by showing maggots on meat came from flies laying eggs.
Francesco Redi
Domain
Heterotrophs that feed by absorbing food through their cell walls; responsible for athlete's foot and ringworm.
Fungi or Fungus
Organisms (including humans) which have nuclei containing DNA belong to this domain.
Eukarya or Eukaryotes.
What do organisms need to power their cells?
Energy
This scientist disproved spontaneous generation by showing that bacteria did not grow in flasks with unbroken necks.
Louis Pasteur
What two words form an organism's scientific name?
Genus and species
Organisms that are so small you need a microscope to see them.
Microorganisms
These organisms do not have nuclei in their cells.
Prokaryotes.
