Any living thing can be called this.
What is an organism?
Small structures or bodies in a cell that are specialized to perform a specific function. Most have a membrane.
What is an organelle?
An instrument that makes viewing cells possible when they are too small to see with the naked eye.
What is a microscope?
An example would be fire, because although it spreads and consumes fuel, it is not considered this since it lacks cells.
What is non-living?
An idea that underpins much of how we study organisms, medicine, heredity, evolution, and all other aspects of life science.
What is cell theory?
A protective layer that covers a cell's surface and acts as a barrier between the inside of a cell and the cell's environment
What is a cell membrane?
The region enclosed by the cell membrane and includes the fluid and all of the organelles of the cell.
What is the cytoplasm?
A scientist who recorded what he saw by making a series of beautiful drawings to document his observations of organisms seen under a microscope.
Who is Anton van Leeuwenhoek?
An example of a thing like this would be a fungus that grows in the soil, consumes energy, and is made of cells.
What is living?
This is the basic unit that makes up all organisms.
What is the cell?
The organelle that contains the DNA (genetic material) of prokaryotic cells.
What is a nucleus?
The large empty space in a plant cell that can store water.
What is a central vacuole?

These entities are made up of one or more cells.
What are all organisms?
A single-celled organism that does not have a nucleus or membrane bound organelles. Its DNA is stored in the cytoplasm.
What is a prokaryote?
A long-chain, double helical molecule that stores the genetic information that a cell needs for all cell processes.
What is DNA?

Who are Matthias Schleiden and Theodore Schwann?
An entity that although it can reproduce and cause disease, it is not considered alive.
