Cell Theory
The invention of this device made the development of cell theory poosible.
What is the light microscope?
These are the four functions of cell division
What are repair, replace, grow and reproduce?
This structure is the cell's gate keeper, letting things in and out
What is the cell membrane?
The needs of a single cell mimic the needs of these
What are living organisms?
The part of the microscope that you place the slide on. Also a favorite with actors.
What is a stage?
All new cells come from these
What are existing cells?
In this stage, the cell grows and replicates DNA
What is Interphase?
Cells in higher organisms can be specialized. Give an example of a specialized cell
What is a brain, blood, nerve, skin, etc cell?
The "structure" of a cell refers to this
What is what it is made of and how it is put together.
He was the first to observe living organisms under a microscope.
Who is Anton van Leeuwenhoek

What is mitosis?
These objects serve the same functions in a cell that organs do in our bodies.
What are organelles?
This large organelle stores a cell's DNA
What is the nucleus?
These microscopes are 5000x more powerful than the most powerful light microscopes
What are electron microscopes
These are considered the basic structure of life
What are cells?
These are the four phases of mitosis
What are prophase, metaphase, anaphase and telophase?
This is the filling of the cell. It supports the organelles
What is the cytoplasm?
Found only in plant cells, this organelle contains chlorophyll
What is a chloroplast?
He observed round openings in cork bark under a microscope and named them cells.
Who was Robert Hooke?
These three tenants are the basis of cell theory
What are All living things are made of cells, cells are the basic unit of structure and function in living things, All new cells come from existing cells.
This is the final stage of the cell cycle
What is cytokinesis?
Plant cells have these. Animal cells do not
What is a cell wall or chloroplasts
Name three organelles found in a cell's cytoplasm?
What is nucleus, endoplasmic reticulum, mitochondria, etc?
Many scientists consider these to be the largest cells in the world. Others think its an ostrich egg.
What are bubble algae or sea pearls?
