This man was a scientist who drew illustrations of the organisms he found in the human mouth which we call bacteria. He discovered that cells were the basic units of life.
Who is van Leeuwenhoek?

This organelle is found in eukaryotic cells, all cellular contents outside the nucleus; in prokaryotic cells, all of the cells' contents
What is cytoplasm?
100
This is the piece that supports the tube and connects it to the base
What is the arm?
100
This is the process by which particles tend to move from an area where they are more concentrated to an area where they are less concentrated
What is diffusion
200
This is the basic unit of all forms of life.
What is the cell?
200
This englishman used an early compound microscope to look at a nonliving thin slice of cork, a plant material.
Who is Robert Hooke?
200
This organelle is a strong supporting layer around the cell membrane in some cells.
What is the cell wall?
200
This is the bottom of the microscope, used for support
What is a the stage?
200
The movement of materials across the cell membrane without using cellular energy.
What is passive transport?
300
This is a fundamental concept of biology that states that all living things are composed of cells; that cells are the basic units of structure and function in living things; and that new cells are produces from existing cells.
What is the cell theory?
300
This German physician concluded that new cells can be produced only from the division of existing cells.
Who is Rudolf Virchow?
300
This organelle breaks down lipids, carbohydrates, and proteins into small molecules that can be used by the rest of the cell.
What is a lysosome?
300
This microscope uses beams of electrons that are focused by magnetic fields instead of using light.
What is an electron microscope?
300
This is the movement of materials against a concentration difference.
What is active transport?
400
This is a unicellular organism that lacks a nucleus.
What is a prokaryotic cell?
400
This man was the german biologist who stated that all animals are made of cells.
Who is Theodor Schwann?
400
This flexible double layered sheet makes up the cell membrane and forms a barrier between the cell and its surroundings.
What is the lipid bilayer?
400
The first lens that is located just above the specimen, it enlarges the image of the specimen. Most light microscopes have several objective lenses.
What is the objective lens?
400
Endocytosis, phagocytosis, and exocytosis are all examples of this
What is bulk transport?
500
The center of an atom, which contains the protons and neutrons; in cell, structure that contains the cell's genetic material in the form of DNA.
What is the nucleus?
500
This man concluded that all plants are made of cells.
Who is Matthias Schleiden?
500
This structure is in animal cells and helps to organize cell division.
What is the centriole?
500
This microscope allows light to pass through a specimen and uses two lenses to form an image.
What is a light microscope
500
This is the diffusion of water through a selectively permeable membrane
