What does the term “protozoan” mean?
It is a term used to group together single celled animals (but isn’t a taxonomic level of classification!)
What are the four functional groups of protozoans? (according to their mode of nutrition/locomotion)
1) flagellated protozoans
2) amoeboid protozoans
3) spore-forming protozoans
4) ciliated protozoans
(representatives from all 4 of these are observed in lab 1)
What not to do in lab?
1) Don’t mix the different cultures
2) use only specific pipette for each culture
3) Don’t mix cultures with tap water
4) keep microscope light low
5) wash used slide throughly before using again for next sample
ocular lens?
- most microscopes are binocular
- bring the specimen into focus using the main knobs, then adjust with ocular lens
- its 10x, meaning the lens magnifies the image by 10
objective lens?
- mounted on the revolving nosepiece
- vary in #, depending on microscope
- lens must be clicked into position above slide
- most compound microscopes have 4 objective lenses
4x lens?
- scanning objective
- works well to locate your specimen
- magnifies by factor of 4
- is the “resting” position
10x lens?
- called the low power objective
- magnifies by factor of 10
- if your microscope doesn’t have 4x, this can be scanning objective
40x lens?
- called the high power objective
- magnifies image by factor of 40
100x lens?
- called the oil immersion objective
- requires drop of immersion oil on the slide to work properly
- magnifies by factor of 100
- don’t use unless specifically asked to! (slide can be broken easily using this lens)
(clean lenses with lens paper, NOT paper towels/shirts!!!!)
stage?
- specimen slides held in place with movable stage clip
- mechanical clips used to move stage backwards/forewards and front/back
Focus knobs?
- two knobs: course and fine
- course focus knob is the larger one and control distance b/w your specimen and objective lens
- quickly moves slide up and down
- only use this knob for 4x and 10x
- fine focus knob is used to get it perfectly clear
- only use this at 40x or 100x
depth of focus?
- the “thickness” of the vertical range in which the specimen remains in focus
- important cuz you’ll need to focus through your specimen so as to view all its structures (not all features will be in perfect focus at any given time)
