An environmental factor that is non-living/never living 

An environmental factor that is living, dead, dormant.

Reproduction that involves only ONE organism

Reproduction that involves TWO organisms. 

Any living thing

The molecule that stores genetic information (blueprint for life). 

The smallest unit of life that can perform all life processes. 

An organism that is one-celled.

An organism that is made up of multiple cells. 

Signals that come from inside environments (stomach growling – hunger)

Signals that come from outside environments (plants growing toward sunlight)

Behavior of an organism as a result of the internal or external stimulus (the effect)

Changes to an organism's DNA, which create traits that are favorable for survival.

Maintain a stable internal environment

Cell with NO nucleus 

Cell that contains a NUCLEUS

An organism that makes its own food 

An organism that consumes other organisms for energy. 

The process by which scientists group living things. 

The science of describing, classifying, and naming organisms. 

Two-part scientific name developed by Carolus Linneaus. The scientific name is made up of an organism's genus and species. The binomial nomenclature uses Latin for a universal language. 

Represents the largest differences among organisms (The broadest level). 

Includes similar species with common characteristics

A group of organisms that are very closely related. They can mate and produce fertile offspring.

A domain made up of prokaryotes, most of which are known to live in extreme environments, that are distinguished from other prokaryotes by differences in their genetics and in the makeup of their cell walls.

A domain made up of prokaryotes that usually have a cell wall and reproduce by cell division. Bacteria live in almost any environment—soil, water, and even inside the human body!​

A domain made up of all eukaryotes (cells that have a nucleus); this domain aligns with the traditional kingdoms Protista, Fungi, Plantae, and Animalia. 

Prokaryotic, unicellular organisms that live in almost any environment, reproduce asexually, and can be autotrophic or heterotrophic. 

Prokaryotic, unicellular organisms that live in harsh environments, reproduce asexually, and can be autotrophic or heterotrophic. 

A kingdom of mostly one-celled (but some multicellular) eukaryotic organisms that are different from plants, animals, archaea, bacteria, and fungi.The “junk drawer” kingdom. Animal-like, plant-like, and fungus-like organisms. 

A kingdom made up of complex, multicellular organisms that are usually green, have cell walls made of cellulose, cannot move, and use the Sun’s energy to make sugar and oxygen by photosynthesis. 

A kingdom made up of complex, multicellular organisms that lack cell walls, can usually move around, and quickly respond to their environment

A kingdom made up of non-green, eukaryotic organisms that have no means of movement, reproduce using spores, and get food by breaking down substances in their surroundings and absorbing the nutrients. 

A tool used to identify items in the natural world. 

what is the cell theory?

Scientist who “coined” the term cells after looking at cork under a microscope. 

Scientist who identified unicellular organisms and named them “animacules”. 

German botanist who discovered plants were made of cells. 

German zoologist who discovered animals were made of cells. 

Scientist who discovered all cells come from pre-existing cells. 

A membrane-bound organelle that contains the cell’s DNA and controls the cell's activities.
