A scientist that study cells
volume_muteCorrect Answer:
cytologist
Reference
A microscope that magnifies objects from 4x to 80x to investigate much larger objects, also called dissecting microscopes
volume_muteCorrect Answer:
stereomicroscopes
Reference
A microscope which utilizes a beam of electrons that travel in shorter wavelengths than those of photons in visible light
volume_muteCorrect Answer:
transmission electron microscope
Explanation
These electrons are passed through a thinly sliced specimen within a vacuum to prevent any electrons from being deflected and absorbed by the gas molecules in the air. Then the electrons are focused with electromagnets on a photographic plate, producing an image that is considerably better than that obtained with a light microscope.
Reference
A microscope which focuses electrons that bounce off the specimen
volume_muteCorrect Answer:
scanning electron microscope
Explanation
Then in the 1950s the scanning electron microscope (SEM) was invented, which focuses electrons that bounce off the specimen. Since the SEM has less resolving power than the transmission electron microscope, it doesn’t require a vacuum and allows researchers to view some smaller organisms alive
Reference
A structural layer surrounding some types of cells, just outside the cell membrane
volume_muteCorrect Answer:
cell wall
Reference
Organisms that carry out all necessary life-supporting functions within one cell without the help of other cells.
volume_muteCorrect Answer:
unicellular organisms
Explanation
Bacteria and protozoa are examples of such organisms
Reference
An organism that consists of more than one cell
volume_muteCorrect Answer:
multicellular organism
Explanation
All species of animals, land plants and most fungi are multicellular, as are many algae.
Reference
Everything within cell plasma membrane, except nucleus is called
volume_muteCorrect Answer:
cytoplasm
Reference
Inside cell membrane, a homogeneous mixture of two or more components in which the particles of the different substances are so small that they cannot be distinguished
volume_muteCorrect Answer:
solution
Reference
Inside the cell, usually contains particles that are too small to be seen but are large enough not to form a true solution
volume_muteCorrect Answer:
colloid
Reference
In cell, the condition of constant internal environment
volume_muteCorrect Answer:
chemical homeostasis
