17
Q

a. Specimen is place here for viewing

A

Stage

18
Q

a. Holds the specimen in place

A

Stage clip

19
Q

a. Used to move the stage the up and

down, left and right.

A

Stage controls

20
Q

a. A hole on the microscope stage
through which the transmitted light
from the illuminator will reach on
the stage.

A

Aperture

21
Q

a. Located at the base
b. Captures the light from the external
source or the voltage (electric
microscope) to have a focus life unto
the specimen.

A

. Light source

22
Q
a. Found under the stage, next to the
diaphragm
b. Ensure clear sharp images
c. Without it, image will not be as
sharp as what we going to observe
under the microscope.
A

Condenser

23
Q

a. Found under the stage as well
b. Control the amount of light from the
light source that will pass through to
the specimen.

A

. Diaphragm

24
Q

→ Always carry your microscope with two hands,
one grasping the arm or back slot and the
other supporting the base.
→ Left- hold the base
→ Right- hold the arm of the microscope

A

CARRYING:

25
Q

→ Turn off light & center mechanical stage
→ Position the nosepiece so that the lowest
scanning (4x) objective is in place.
→ Remove the slide from the stage and put it in
the proper place.
→ Clean the stage and lenses with gauze and
lens cleaner and wipe off any oil.
→ Wrap the cord around the arm.
→ Carefully carry with two hands and gently
place the microscope in the proper cabinet.

A

PUTTING AWAY:

26
Q

→ Set the microscope on a flat, solid support
and in a position where it will not easily be
knocked off.
→ Properly coil the cord to avoid tripping over
it.

A

TABLE PLACEMENT:

26
Q

→ Lenses must be clean for resolution.
→ Use only lens paper or gauze and cleaning
solution.
→ Never use your finger, handkerchief, paper
towels or spit to clean the lenses.
→ Do not remove any parts for cleaning; it only
allows dust to enter the microscope.

A

CLEANING

the cytoplasm of the nuclear
envelope
o Cytoplasm contains membrane
organelles: ribosomes, cytoskeleton
o Have cell wall on the surface and
have undergone the process of
differentiation and specialization.

30
Q

such as those bacteria, have

a simple organization.

A

separated form the cytoplasm by
membrane
o Do not have any membrane
organelles
o Small ribosomes are present
o Have cell wall on the surface
o Reproduce thorough asexual
reproduction or by amitosis or binary
fission which occurs immediately
after DNA replication.
