Microscope
To properly carry the microscope hold it by the base and the
arm
A single celled organism is known as what?
Unicelluar
Which organelle contains genetic material (DNA)
The nucleus
Which organelle is the control center of the cell
The nucleus
If you move the slide up what way does it the slide appear to move?
down
In our classroom the microscope we use is a
Compound microscope
Name two differences in plant and animal cells (besides shape)
Plant cells contain a cell wall and chloroplasts
Something like a cell membrane that only lets certain things in and out is called
The organelle where cholorophyll is found
chloroplast
If you move the slide to the right which way does the slide appear to move?
to the left
The compound microscope is accredited (in other words, discovered or developed) to which scientist
Robert Hooke
True or False: All cells contain a cell wall
False
Which organelle is the powerhouse of the cell and creates energy?
The mitrochondria
In a model of a cell , the cytoplasm is the gel-like substance that fills the cell and holds the organelles in place. How does the cytoplasm contribute to the cell's overall function?
It provides a medium where chemical reactions and organelle movement can occur.
If you change from low to high power on the microscope what two differences to you see
more detail and less of the object
What should you never use on the highest power of the microscope
the coarse adjustment
If something is magnified 100X and the eyepiece is 10X what does the objective lens have to be equal to
10X
What job does chloroplasts do?
They are where photosynthesis takes place.
Developing a model of a multicellular organism involves showing how different types of cells work together. Which example best demonstrates this principle?
Muscle cells contracting to move a bone, while nerve cells send the signals.
What organelle recycles old cells
Lysosomes
If the eyepiece is 10X and the objective lens is 40X what is the magnification of the object?
400X
Name the three parts of the cell theory
1. All living things are composed of cells 2. Cells are the basic units of life 3. New cells are produced from existing cells
A scientist observes a bacterium under a microscope. The bacterium, made of only one cell, is actively moving, consuming food, and growing. This observation provides evidence that even a single cell can carry out all of the life functions necessary to be classified as a(n)...
A complete organism
What do mitrochondria and chloroplasts have in common?
The both make energy but chloroplasts are only in plant cells
If something is labeled as 200X how many times is it magnified?
200
