Things, the Discovery of Cells, and Microscopes

Microscopes allowed people to discover cells.
If a plant moves towards light, the light is the stimulus and the plant’s movement is the
response.
Living things only come from other living things.
Leeuwenhoek saw living cells. Hooke did not.
The Coarse Adjustment Knob is used to focus the image in the microscope.
To calculate Total Magnification, multiply the eyepiece times the objective.
An example of a unicellular organism is a person.
All living things do not move.
The microscope bag should go somewhere safe.
Always start in Scanning Power.
When switching objectives, you should first take your eye off the eyepiece and look
directly at the stage.
Next you should raise the objectives with the coarse adjustment knob.
Next you switch the objectives.
Finally lower the objectives and look through the eyepiece.
Redi used jars of meat to disprove Spontaneous Generation.
Pasteur used flasks of broth to disprove Spontaneous Generation.
An example of a multicellular organism is grass.
The diaphragm controls the amount of light going in.
The Cell Theory states that all living things are made of cells, cells are the basic unit of
life, and all cells come from other cells.
Hooke looked at cork from a tree.
Hooke was the first person to see cells.
Water is not a living thing.
Cell means little room.
Leeuwenhoek said that animalcules are little animals.
Asexual reproduction only involves 1 parent.
DNA is found in the nucleus of every cell.
Hydras reproduce asexually.
DNA contains all of your genetic characteristics.
Blood carries oxygen to every cell in your body.
Carbohydrates are food for your cells.
About 70% of each cell in a human is made of water.
It took 200 years for people to realize that all living things are made of cells because the
earliest microscopes could not see the thin cell membrane in an animal cell, they could
only see the thick cell wall of a plant cell.
The average human body contains trillions of cells.
The cell’s main source of energy is carbohydrates.
Use your strong hand on the arm of the microscope, your weak hand below.
If you have a high metabolism, you burn energy quickly.
Development means change.
Unicellular organisms are made of one cell.
Hooke looked at cork under the microscope.
The microscope is used to make small objects appear larger.
