**Cell Type** - Algae are eukaryotic organisms **Characteristics** - unicellular or multicellular - are photosynthetic. **Examples** - Ex: Kelp & Seaweed
26
Q: Describe Microscopic animals.
A: Microscopic animals are multicellular eukaryotes that have a life cycle and can cause disease.
27
Q: What are some diseases caused by microscopic animals?
A: - Parasitic worms: Tapeworms, hookworms. - Scabies: Human itch mite. - Lice: Do not cause disease but can carry pathogens.
28

37
Q: What are pathogens?
A: Pathogens are disease causing microbes.
38
Q: Compare Infectious v. Noninfectious diseases.
A: - Infectious Diseases: Diseases that can be spread from person to person (animal to person) - Non-infectious Diseases: Diseases that cannot be spread from person to person. They are based on genetic predisposition & lifestyle factors. --> Ex: Cancer, Asthma, Arthritis, Diabetes
39
Q: Describe some examples of Contact Transmission.
A: - Direct Contact: Direct body contact - Droplet Transmission: Short-range coughing or sneezing
40
Q: Describe some examples of Indirect Contact Transmission.
A: - Airborne: Pathogens in the air carried by dust or droplets. - Vehicles: Food, water, biological products, fomites - Vectors: Mosquitoes, fleas, ticks, can carry pathogens passively or the pathogens multiplies in vector
41
Q: What are light microscopes?
A: Light microscopes use light for visualization. These microscopes can magnify up to 1,000x.
42
Q: What are brightfield microscopes?
A: Microscopes where the background is illuminated. Used to see microbes that have been stained.
43
What microscope would best be used to see microbes that have been stained?
Brightfield microscopes
44
Q: What are darkfield microscopes?
A: Microscopes where the background is dark. Used to see live, unstained specimens.
45
What microscope would best be used to see live, unstained microbes?
darkfield microscope
46
Q: What are phase-contrast microscopes?
A: Microscopes that use contrast without staining the specimen.
47
What microscope would use contrast to see a microbe without staining them?
Phase-contrast microscope
48
Q: What are fluorescence microscopes?
A: Microscope used to see stain that contain particles that will appear fluorescent.
49
What microscope would be used if the specimen was stained with a fluorescent stain?
Fluorescence microscope
50
Q: What are confocal scanning laser microscopes?
A: Microscope that uses fluorescence to view a single plane. Each image is an optical slide through a specimen.
51
Q: What are differential interference contrast microscopes?
A: Very contrasted to give an image a 3D & shadowed appearance.
52
Q: What are electron microscopes?
A: Electron microscopes use electrons for visualization instead of lights. These microscopes can be used to magnify 10,000x - 100,000x
53
Q: What are transmission electron microscopes?
A: Microscopes where electrons pass through the specimen.
54
Q: What are scanning electron microscopes?
A: Microscopes where electron bounce off specimen to create a surface image.
55
Abby wants to see detailed, highly resoluted surface structures of a specimen. What microscope would be best to see this result?
Scanning electron microscope
