Adjustable Parts of a Microscope | Characteristics of Life | Types of Cells | Concepts of Cell Theory | Nonmoving parts of a Microscope |
---|---|---|---|---|
Coarse & fine adjustment knobs
These parts allow for changes in the height of the stage for focusing (brings stage closer to or farther away from the objective lens; Can be used for fine and clear focusing)
|
True
True or False:
All living organisms need energy to carry out life processes |
Nucleus
This is the basic cell structure that is present in many, but not all, living cells
|
One or more cells
Every living thing is made of this
|
On the stage
Slides/specimens are placed here for viewing
|
Revolving nosepiece
This part adjusts which objective lens is in place to be used
|
False
True or False:
Al living organisms maintain a stable external environment |
Prokaryotic cells
These cells do not have a nucleus.
|
Cells
These carry out the functions needed to support life
|
Stage clips
This holds the slide/specimen in place
|
Objectives (lenses)
This part contains three different magnifications (4x, 10x, 40x) to adjust how magnified a specimen may be
|
True
True or False:
All living organisms grow and develop. |
Eukaryotic cells
These cells contain a nucleus.
|
Other living cells
Cells come only from _____.
|
Arm
This holds the nosepiece, stage, and adjustment knobs in place and also attaches to the base
|
Light source
For most microscopes, this is a light bulb that shines light up through the stage to the specimen. However, some microscopes have a mirror that has to be adjusted by reflecting light from the environment
|
Their environment
All living organisms respond to this
|
Multicellular
Eukaryotic cells are found mainly in these organisms
|
Confirmed
Pasteur's experiments did this to the cell theory
|
Body tube
This allows for the ocular lens and nosepiece to be at the correct distance apart
|
Diaphragm
This part rotates underneath the stage to adjust the amount of light that is passed through to the specimen
|
Living things/ organisms.
Mushrooms, daisies, cats, and bacteria are all this
|
Prokaryotes
These were the first type of organisms to evolve and are still the most common organisms today.
|
Spontaneous generation
The idea that bacteria grew from nonliving materials is called thiis
|
Ocular lens/ eyepiece
This contains a lens at 10x magnified; where you look to observe your specimen
