What is a microscope?
What are mitochondria?

What is a life cycle?
A cell's external boundary for the material inside the cell.
What is a cell membrane?
A bubble-like organelle in cells; generally used for storage.
What is a vacuole?
The step-by-step process of cell division that ensures that the two new cells formed will be genetically the same as the original cell.
What is mitosis?
Plantlike organisms in Kingdom Protista; usually perform photosynthesis and are not mobile.
What is algae?
The ability to do work.
What is energy?
A jelly-like substance consisting mostly of water and containing many substances, such as proteins and fats, that are essential to the cell.
What is cytoplasm?

What is a chloroplast?
Organisms in Kingdom Eubacteria; the smallest living things known.
What is bacteria?
List the characteristics of living things.
They reproduce
They respond to their environments
They use energy
They are made of cells
A theory stating that all living things are made of cells and that the cell is the smallest form of life.
What is cell theory?
The large organelle in a cell that contains the chromosomes.
What is a nucleus?
A green pigment that absorbs energy from sunlight and uses it to produce food and energy for the plant.
What is chlorophyll?
A group of the same kind of organisms living together; examples include bacteria and fungi.
What is a colony?
List the classification of living things in order.
