How is a compound microscope different than a magnifying glass?
The compound microscope has more than 1 lens.
What was Zacharias Jansen’s discovery? Why is it important?
He discovered the compound microscope and you could now see a whole new world.
What was Antionie van Leeuwenoek’s greatest contribution to science?
He added light to the microscope.
What was important about Robert Hooke’s discovery?

What is a cell?
A cell is the smallest unit of a living thing that can perform live functions.
What is the cell theory?
A - All cells come from existing cells
B - All organisms are made up of cells
C - Cells are the basic unit of all organisms
How are cells the same?
They are the same in the nucleus, cell membrane, mitochondria and vacuoles
Define multicellular organism? Name 3 multicellular organisms?
Definition: Organisms that are made up of more than one cell.
Examples: Humans / Plants / Animals
Define unicellular organisms? Name 3 unicellular organisms?
Definition: Organisms that are made up of one cell only.
Examples: Euglena / Paramecium / Amoeba
What can a unicellular organism do?
A unicellular organism can make or take food and move.
Draw an Euglena. Write 3 things about an Euglena?
A Euglena is Unicellular / Flagellum / Lives in pond water
Draw a Paramecium. Write 3 things about a Paramecium?
A Paramecium has cilia / lives in a pond / moves quickly.
Draw an Amoeba. Write 3 things about an Amoeba?
Three things about an Amoeba are that it is false foot / surrounds food to eat / causes upset stomachs.
Name 3 organelles and describe what they do for a cell?
Nucleus - brain, control center of a cell.
Mitochondria - produces energy.
Vacuoles - makes food.
How are plant cells different from animal cells?
Plant cells have a cell wall and chloroplasts and animal cells do not.
Why do cells need energy?
They need energy in order to eat / to move / to perform life functions.
Name 3 processes that allow materials to move into and out of a cell?
Diffusion - particles move in and out of a cell.
Osmosis - water moves in and out of a cell.
Active Transport - energy is used to move things in and out of a cell.
What happens during respiration, and why is this process important to all cells?
Energy is made to help the cell do it’s job.
How do some cells make their own food? What is this process called?
Cells make their own food through the process of photosynthesis. Food is made to provide fuel for the cell.
How do cell divide?
Mitosis - Z you will need to be able to put pictures in order.
What is the most important thing we need to realize about God and His creation?
God made all things and it is good.
What is the importance of Genesis 1:24?
All things are made according to there kind.
God’s creation of cells shows us what about God’s character?
His great creation too detail, He is creative and He is in control.
