What type of beam does a light microscope use?
A
beam
of
light
What type of images can light microscopes see?
Colour images
Why is the resolution power of light microscopes lower?
Because they use a longer
wavelength
Can light microscopes observe live specimens?
Yes
How does the magnification of light microscopes compare?
It is
lower
What type of beam does an electron microscope use?
A beam of
electrons
What type of images can electron microscopes see?
Black and white
images
Why must specimens be dead for electron microscopy?
Because
electron microscopes
cannot observe live specimens
How does the resolution power of electron microscopes compare to light microscopes?
It is
higher
How does the magnification of electron microscopes compare?
It is
higher
What advantages do electron microscopes have over light microscopes?
Higher magnification
and
resolution
What is the calibration process for microscopes?
Identify
eyepiece units
to
stage micrometre units
.
Start from zero at the same point.
Multiply eyepiece unit by
divisions
(
0.1
/
0.01
).
Ensure each unit is the same.
What is the first step in calibration for microscopes?
Identify
eyepiece
units to
stage micrometre
units
Why is it important to start from zero in calibration?
To ensure
accurate
measurement comparison
If you have 1 eyepiece unit, how do you convert it to stage micrometre units?
Multiply by the
divisions
between eyepiece
What must be ensured when calibrating units?
Each
unit
must
be
the
same
How do you convert from µm to mm?
Divide by
1000
How many millimeters are in a meter?
1000
mm
What is the conversion of 1 mm to meters?
0.001
m
How is 1 µm expressed in terms of mm?
1 mm ÷
1000
How many millimeters are in a centimeter?
10
mm
What is the conversion factor from mm to nm?
Multiply by
1,000,000
What are the key metric conversions mentioned?
1 m
= 1000 mm
1 mm
= 0.001 m
1 µm
= 1 mm ÷ 1000
1 cm
= 10 mm
mm to nm
= x1000000
Aerobic respiration
produces
ATP
from
glucose
using
oxygen
as an electron acceptor.
The mitochondria is the site of aerobic respiration
